Christina Johnson suffered traumatic facial injuries when she was hit by a hockey stick during a game. 

Playing sport with a cheap mouthguard purchased at a pharmacy or sports store?

Christina Johnson’s horrific injuries may prompt you to get a stronger one made by a dentist.

Last week Ms Johnson suffered severe trauma to her mouth when she was hit by a hockey stick during a game in Tasmania. She was wearing a mouthguard that offered little protection.

As a result, one of her front teeth was knocked out, another one was fractured and others were pushed back and displaced. Her lips and gums were also split by the force of the hockey stick.

Ms Johnson, now facing extensive reconstructive surgery, is one of many Australians that dentists say are sustaining potentially preventable injuries during sport because they don’t have a custom-made mouthguard.

Although the Australian Dental Association says a bespoke mouthguard will cost about $250 (compared to about $10 for an over-the-counter mouthguard), it may save you serious pain and thousands of dollars for surgery if you get injured.

Dr Peter Alldritt​, chairman of the association’s Oral Health Committee, said people should give as much thought to their mouthguard as other sporting equipment because “$250 doesn’t go far when it comes to having a tooth fixed”.

“Not all of them (mouthguards) offer equal protection, and some of them can actually cause even more damage,” he said.

“Over-the-counter mouthguards are often difficult to wear and don’t provide the same level of protection as custom-fitted mouthguards; in contrast, custom-fitted mouthguards allow ease of breathing and speaking, and are far more comfortable.”

An association survey of about 1200 people recently found that three in four active adults who wear a mouthguard were using over-the-counter ones. Among children, it was one in two.

Ms Johnson said she had never considered getting a custom-fitted mouthguard from a dentist before she was injured last week.

“I thought the mouthguard I was wearing during the game, which I had bought from a store, was good enough”.

There is limited research assessing the protective effects of various mouthguards on athletes but a study of 301 Australian Rules footballers in 2001 concluded that those wearing custom-fitted mouthguards had a significantly lower rate of head and facial injuries than other players.

Sports Medicine Australia also recommends custom-fitted mouthguards for all contact sports to reduce the risk and severity of dental injuries because they can accommodate people’s unique arrangement and number of teeth and provide protection of vulnerable areas, such as the bony gum area finishing close to the junction of the inside of the cheek.

The group says a mouthguard is protective only if an adequate thickness of mouthguard material (4 millimetres – thickness of two matches) covers vulnerable areas including the biting surfaces of the upper teeth and the visible surfaces of the six front upper teeth upon which the lips rest.

15 Tooth Problems you should know about

woman_with_toothache image www.perfectwhite

You’ve made a dentist appointment, and it can’t come soon enough. Meanwhile, it can help to rinse your mouth with warm water, floss to remove food caught between teeth, and take an over-the-counter pain reliever.  If you notice swelling or pus around the tooth, or if you have a fever, that could be a sign that you have an abscess, a more serious problem. See your dentist as soon as possible. You may need antibiotics and possibly a root canal.

2. Stained Teeth

stained_teeth image

Your teeth are like your laundry: The right approach will remove many stains. Foods, medications, tobacco, and trauma are some of the things that can discolor your teeth.  You have three options for whitening them. Your dentist can use a whitening agent and a special light in his office. Or you can bleach them at home with a plastic tray and gel from your dentist or a store. The simplest choice, whitening toothpaste and whitening rinses, only remove surface stains.

3. Cavities

xray_of_tooth_decay image

These little holes in your teeth are bad news. You get them when a sticky bacteria, called plaque, builds up on your teeth, slowly destroying the hard outer shell, called enamel. Adults can also have problems with tooth decay at the gum line and around the edges of earlier fillings. To prevent it, brush your teeth at least twice a day with a fluoride toothpaste, limit snacks, floss daily, rinse with a fluoride mouthwash, and keep up with your dental appointments. Ask your dentist if you should use a sealant.

4. Chipped Tooth

chipped_tooth-smile image

It’s the No. 1 type of dental injury.  An accident can cause a chip. So can something much less dramatic, like chomping popcorn. The fix depends on whether the pulp, or part of the tooth that contains blood vessels and nerves, is damaged. If it’s not, your dentist will bond a strong resin material to the tooth, replacing the chipped area.  If the pulp is at risk, you may need a root canal followed by a veneer or crown

5. Impacted Teeth

impacted_wisdom_tooth image

An adult tooth that doesn’t come in properly is “impacted.” It usually happens when a tooth is stuck against another tooth, bone, or soft tissue. If it  isn’t bothering you, a dentist may recommend leaving it alone.  But if it hurts or may cause problems later on, an oral surgeon can remove it.

6. Cracked Tooth


You were playing football without a mouth guard, or chewing, or maybe you don’t know how it happened, but now you’ve got a cracked molar. Can your dentist save the tooth? It depends. If the crack is just on the surface, a filling may do the trick. But if the tooth is sensitive to hot and cold, the problem is more complex. Try to chew on the other side until you see your dentist. If the crack is above the gum line, you may need a root canal and a crown. A deeper crack means the tooth must be pulled, though.

8. Too Many Teeth: Hyperdontia

hyperdontia-teeth-problem image

How many teeth are in your mouth? If you’re like most people, you had 20 primary, or “baby,” teeth, and you now have 32 adult teeth.  It’s rare, but some people have extra teeth, which is called hyperdontia. People who have it usually also have another condition, such as a cleft palate or Gardner’s Syndrome (which forms tumors that aren’t cancer). The treatment is to get the extra teeth removed and use orthodontics to correct the bite.

9. Crooked Teeth & Braces

teeth-braces image

The fix — orthodontia — isn’t just for kids. And straightening crooked teeth and aligning your bite doesn’t just make for a prettier smile. It can be an key part of improving overall dental health, relieving symptoms like jaw pain.  Orthodontists may use braces (metal or trays), aligners, and retainers.

10. Gap Between Teeth

gap_between_front_teeth image

You may not consider a gap between the front teeth a problem at all. Famous people who sport the look include singer Madonna, actress Anna Paquin, model Lauren Hutton, and football player turned TV co-host Michael Strahan. If you want to correct it, though, your options include orthodontics to move teeth closer together and cosmetic solutions like veneers or bonding.

11. Gum Problems

gingivitis-gum-disease image

Do your gums bleed easily? Are they tender? Do you notice them pulling away from your teeth? You might be in the early stages of gum disease (gingivitis) or in the more advanced stage (periodontitis). A buildup of plaque, a sticky bacteria, below the gum line causes it. Left untreated, periodontitis can cause bone loss, and your teeth might shift or become loose. That can make it harder to chew and even speak. To avoid gum disease, brush, floss, and rinse with an antiseptic mouthwash daily, and see your dentist for regular cleanings.

12. Clenching or Grinding Your Teeth

teeth-grinding-bruxism image

Grinding your teeth is called bruxism. Stress is one of the causes. Misaligned teeth or sleep issues can also be culprits among adults. (Among kids, causes can include allergies.) Bruxism can give you headaches, a sore jaw, and cracked or loose teeth. If you grind your teeth at night, ask your dentist to fit you with a mouth guard. If it’s a daytime problem, try meditation, exercise, or other ways to curb stress.

13. Wisdom Teeth Problems

impacted_wisdom_teeth images

If your dentist says your wisdom teeth, or third molars, came in problem-free, count yourself lucky. Most people — 90% — have at least one wisdom tooth that’s impacted, or not able to fully grow in. Problems with your wisdom teeth can cause cavities, damage to neighboring teeth, and gum disease. Wisdom teeth generally come in between the ages of 17 and 25. Your dentist should track their progress. If they become a problem, you may need to get them removed.

14. No Room to Floss

man_flossing_teeth image

No matter how tight the fit, there should always be room for floss between your teeth. If not, you may need to switch to a thinner floss or a waxed one. You can also try a different kind of tool, such as a looped flosser or a dental pick. Experiment until you find a product that works for you, and then use it every day. Flossing is a must for good dental health.

Do Grills Cause Problems?

katy_perry_dental_grill image

Experts don’t know yet if this fashion statement is bad for your teeth. But bonding a decorative metal cover to the teeth with glue not meant for use in your mouth can do damage. And a grill made from less expensive metal than gold or silver could irritate your mouth. Always remove a grill before you eat, and make sure you keep it, and your teeth, clean.

Blizzident “toothbrush” is claimed to clean your teeth in 6 seconds see video here


With the new Blizzident toothbrush (if it can be called a toothbrush), a full and complete cleaning of the teeth can reportedly be accomplished in just six seconds.

When it comes to things that people don’t do as often or as well as they should, tooth-brushing would have to be at the top of the list. While it usually just comes down to laziness, a lot of people claim that they don’t brush their teeth properly because they don’t have time. Well, with the new Blizzident toothbrush (if it can be called a toothbrush), a full and complete cleaning of the teeth can reportedly be accomplished in just six seconds.

blizzident-teeth-image www.perfectwhiteteeth (3)

Before they can receive a Blizzident, users first have to go to their dentist and get an impression made of their teeth. Next, a 3D digital model of that impression is uploaded to the Blizzident company’s server. The company proceeds to create a 3D-printed plastic negative mold of the teeth, which is lined with approximately 400 toothbrush-style angled bristles. That mold is the actual Blizzident toothbrush, and is sent to the buyer.

To brush their teeth, users just put the Blizzident into their mouth, bite up and down into it, and grind their teeth back and forth. Because it’s an exact fit for their teeth, six seconds of chomping and grinding is reportedly long enough for the bristles to get into all the nooks and crannies, including between teeth and along the gum line.

If they wish to, users can also thread dental floss between the individual tooth impressions on the Blizzident, causing that floss to be pushed up between the teeth when they bite down. A role of floss can be held in a dispenser on the front of the brush.

blizzident-teeth-image www.perfectwhiteteeth (1)

Finally, a tongue scraper/brush bridges the top of the toothbrush. Users just run their tongue back and forth against it.


One Blizzident is said to be good for a year of use, after which users can get a completely new one, or send their old one in for cleaning and re-bristling. A buyer’s first brush will cost them US$299, with subsequent replacement units priced at $159, and refurbishments of existing units costing $89. The company also notes that getting the initial impression made by a local dentist should cost between $75 and $200, depending on the technique used.

Animation depicting how the brush is claimed to work can be seen in the video below.

Toothpaste ingredient repairs teeth while you are sleeping

biominf-toothpaste-image www.perfectwhiteteeth (2)

The new toothpaste aims to tackle dental decay through a slow release of calcium, phosphate and fluoride ions. View gallery (2 images)

A new toothpaste technology, known as BioMin, is designed to replace minerals lost from tooth enamel, working while the user sleeps to prevent decay. Available to dentists as a toothpaste called BioMinF, and set to be marketed to consumers in the near future, the product is long-acting, and also tackles sensitivity.

Dental decay and sensitivity is extremely prevalent, with some 42 percent of children between the ages of 2 and 11 affected by it, and a whopping 92 percent of adults between 20 and 64 having to deal with it at some point.

A new toothpaste called BioMinF, based on research from the Queen Mary University of London and Imperial College London, aims to tackle dental decay through a slow release of calcium, phosphate and fluoride ions. Whereas normal toothpastes wear off after only a couple of hours, BioMin pastes work for 8-12 hours after brushing, with the flouride – which is resistant to the acid found in things like soft drinks – forming a protective layer over the enamel.

The calcium and phosphate do even more, working with the saliva in the mouth and combining to form a new mineral that’s able to strengthen and rebuilt the tooth structure. Sensitivity is tackled by forming a barrier over open tubules, which provide access to open nerves. The BioMin tech seals off the nerves, lowering sensitivity, particularly to hot and cold food and drink.

biominf-toothpaste-image www.perfectwhiteteeth (1)

Interestingly, the new sensitivity and decay-tackling toothpaste tech could, according to the team behind it, also appear in other dental hygiene products.

“The technology behind BioMin is not however exclusively designed for toothpastes,” said the company’s chief scientific officer Professor Robert Hill. “It can also be incorporated in other professionally applied dental products such as cleaning and polishing pastes, varnishes and remineralizing filling materials.”

BioMin Technologies – the company behind the breakthrough ingredient – is aiming to commercialise the development of the product, with a fluoride-free version also in the works. The BioMinF toothpaste is available to dentists via wholesalers right now, priced at £5 (US$7) for a 75 ml tube. For everyone else, you can expect the new paste to be on store shelves by the end of the year.

Tiny Silica Particles Could Maybe Repair Damaged Teeth

silica sand pile conveyor image

Researchers at the University of Birmingham have shown how the development of coated silica nanoparticles could be used in restorative treatment of sensitive teeth and preventing the onset of tooth decay.

The study, published in the Journal of Dentistry, shows how sub-micron silica particles can be prepared to deliver important compounds into damaged teeth through tubules in the dentine.

The tiny particles can be bound to compounds ranging from calcium tooth building materials to antimicrobials that prevent infection.

Professor Damien Walmsley, from the School of Dentistry at the University of Birmingham, explained, “The dentine of our teeth have numerous microscopic holes, which are the entrances to tubules that run through to the nerve. When your outer enamel is breached, the exposure of these tubules is really noticeable. If you drink something cold, you can feel the sensitivity in your teeth because these tubules run directly through to the nerve and the soft tissue of the tooth.”

“Our plan was to use target those same tubules with a multifunctional agent that can help repair and restore the tooth, while protecting it against further infection that could penetrate the pulp and cause irreversible damage.”

The aim of restorative agents is to increase the mineral content of both the enamel and dentine, with the particles acting like seeds for further growth that would close the tubules.

Previous attempts have used compounds of calcium fluoride, combinations of carbonate-hydroxypatite nanocrystals and bioactive glass, but all have seen limited success as they are liable to aggregate on delivery to the tubules. This prevents them from being able to enter the opening which is only 1 to 4 microns in width.

However, the Birmingham team turned to sub-micron silica particles that had been prepared with a surface coating to reduce the chance of aggregation.

When observed using high definition SEM (Scanning Electron Microsopy), the researchers saw promising signs that suggested that the aggregation obstacle had been overcome.

Professor Zoe Pikramenou, from the School of Chemistry at the University of Birmingham, said, “These silica particles are available in a range of sizes, from nanometer to sub-micron, without altering their porous nature. It is this that makes them an ideal container for calcium based compounds to restore the teeth, and antibacterial compounds to protect them. All we needed to do was find the right way of coating them to get them to their target.  We have found that different coatings does change the way that they interact with the tooth surface.”

“We tested a number of different options to see which would allow for the highest level particle penetration into the tubules, and identified a hydrophobic surface coating that provides real hope for the development of an effective agent.”

Our next steps are to optimize the coatings and then see how effective the particles are blocking the communication with the inside of the tooth.  The ultimate aim is to provide relief from the pain of sensitivity.

DIY Dentistry: How This College Kid Fixed His Teeth Using a 3D Printer

Braces. The word triggers in me flashbacks of rolling balls of wax onto the wires to prevent the inside of my mouth from being torn open, or choosing which color rubber-bands I wanted to display each month (orange and black in October. Red and green in December. Red, white, and blue in July). I was one of the lucky adolescent ducks who got to don headgear while I slept.

Ah, memories.

The orthodontist’s office becomes a kind of second home during this coming-of-age period of a teenager’s life. Most teenagers, that is.

Amos Dudley, a 3D artist and New Jersey Institute of Technology student, has figured out how to create his own set of clear Invisalign braces after failing to wear his retainer, consequently causing his teeth to shift back into chaos. But being the broke (albeit, enterprising) college kid that he was, Amos decided to take matters into his own hands.

Kids, don’t try this at home.

First, Amos took a mold of his teeth, using alginate powder, and placed it into a yogurt container (oh college) filled with Permastone. He then scanned the casing, generating digital models for several sets of aligners—which he then 3D-printed.

As he documented on his blog: “Creating the animation was…fairly trivial—I separated the visible crowns of the teeth from the gumline, and then made a manifold model from each of the shells. I didn’t bother adjusting the geometry of the gums—they are soft. Then it was just a matter of animating them into their correct positions. I measured the total distance of travel, and divided it by the maximum recommended distance a tooth can travel per aligner.”

Next, using a vacuum form machine, Amos created plastic aligners that fit his 3D-printed models, utilizing the same plastic (and therefore safe) retainer material orthodontists use.

Fun fact numero uno: 3D-printing the actual aligners wouldn’t work.

Fun fact numero dos: apparently you can buy retainer plastic on eBay. “The sale of dental supplies really isn’t tightly controlled,” Amos told Gizmodo. “Who wants them other than dentists?”

The result?

Amos admits that the aligners are more comfortable than braces. “I’ve been wearing them all day and all night for 16 weeks, only taking them out to eat. I’m planning on fabricating a bunch of retainers for the current position, which I can use—till I die—at night.”

Of course, because this process involves your face, actual dental professionals advise against this sort of Martha-Stewart-do-it-yourself-teeth-straightening business. Lots of other people have tried and failed (miserably) to fix their pearly whites. (Don’t Google this if you want to keep your lunch down).

Associate professor of orthodontics at the University of Minnesota School of Dentistry Brent Larson said: “I’m impressed with the way Amos was able to use the scanning and printing technology that he had available to engineer and produce his own aligners but a little frightened that he would actually use them to treat himself without a professional assessment of the health and function of the teeth.”

You don’t need to tell me twice. One of the most scarring movie scenes I’ve ever watched is from Castaway (you know, the Tom-Hanks-Wilson-volleyball-love-story), where Hanks’ character knocks out a rotting tooth using a giant rock and an ice skate blade. While Amos’ denture venture is incredibly impressive, I’m happy leaving my teeth to the professionals.

The bite evolution: Your teeth will tell where you came from

Science reveals the secrets of super-sized mammals

Modern diet helping bacteria to wreck our teeth

They’re good for biting, chewing and filling out a cheesy smile for the camera. But teeth have also been shown to be a surprisingly nifty way to track human evolution.

New research has shown that the evolution of teeth, long thought to be a random process, follows a pattern.

A team of international researchers led by Monash University evolutionary biologist Alistair Evans established the pattern applies to up to 90 per cent of human, mammal and hominins.

The main rule is that the biggest teeth for australopiths (the first branch of the hominin tree from which humans evolved) are their back molars, or wisdom teeth. Meanwhile the biggest teeth in humans is the front molar.

“It was always hard to see the forest for the trees because every fossil had to be looked at independently. But here we can see a general pattern and we can be sure that it’s definitely the case,” Dr Evans said.

The newly-defined developmental pattern, outlined in the journal Nature on Thursday, is known as “the inhibitory cascade”.

It sheds lights on how humans and other mammals develop teeth, a process which begins in the embryo.

Understanding how teeth form has uses in fields from academia to cosmetic and medical treatments.

“If we want to do any bioengineering, say grow-your-own teeth, we need to understand these processes,” Dr Evans said. “It’s fundamental research.”

The findings will also enable palaeontologists working with incomplete fossilised jaws to literally “fill in the gaps” and make an informed assessment of the size of the missing teeth.

Dr Evans said when looking at three teeth in a row, the middle tooth would be the average size of the teeth sitting either side.

“This gives us a starting point, as we can compare any new fossil with our expectations … and if we do find some exceptions or changes then we can say ‘well, something really interesting must be happening here’,” he said.

But more importantly, the realisation gives a sense of order to a process previously believed to be random.

“When people had looked at human evolution before they thought ‘everything’s changing all over the place and it’s all very confusing’,” Dr Evans said. “But what we have now is a general framework or a default pattern of development to say that pretty much all hominins and probably all mammals develop in this same way.”

The size and proportion of teeth can reveal not only when meat started to be eaten but also when cooking and the use of tools began. Each of these changes affect tooth size, because suddenly teeth could be smaller.

The 11-member research team began looking at mouse tooth development and established the “inhibitory cascade” rule before confirming the pattern in humans.

To do that they studied tooth measurements from every hominin fossil found to establish that the pattern existed there, which it did. The researchers then tested their theory out on great ape and human data to see if the pattern was evident.

“It was very obvious, immediately,” Dr Evans said. “But nobody had noticed it before.”

1…Ax the Dental Visit Anxiety

If being in the dentist’s chair makes you anxious, encourage calm by bringing a music player and headphones to your next appointment. And because some people hold their breath when they’re nervous — boosting that anxious feeling — focus on breathing regularly. Above all, communicate with your dentist. They understand your fears and want to help.

red lips line

2…Floss First or Brush First?

woman_flossing_teeth image

Flossing first helps make brushing your teeth more effective by removing food that gets trapped between teeth. If handling floss flusters you, look for floss holders at the drugstore. When it’s time to brush, be sure to angle bristles 45-degree at the gum line, then brush gently, moving the brush back and forth.

red lips line

3…Go Easy With Toothpicks

man_picking_teeth_with_toothpick image

If you don’t have floss, a toothpick will work to remove food stuck between teeth, but be gentle. It’s easy to press too hard and damage your gums, or even worse, break off a toothpick below the gum line. Floss helps remove food from between teeth better than a toothpick and fights plaque buildup by getting rid of bacteria that form there. Regularly using a toothpick to remove food trapped in a single area may indicate a bigger problem that requires a dentist’s attention.

red lips line

4…Replace Your Toothbrush

sagging_toothbrush image

Toothbrush bristles fray, flatten, and wear over time. To help keep your smile bright, replace your manual toothbrush every three or four months; for electric toothbrush heads, follow the manufacturer’s advice. Feeling sick? Avoid harboring germs by replacing your toothbrush at the beginning and end of your illness.

red lips line

5…Say Cheese for White Teeth!

woman_looking_into_cheese_display image

The casein and whey protein in cheese can help keep your tooth enamel in top form by reducing demineralization. A bonus: Cheese also has vital, tooth-building calcium. Don’t forget to include vitamin D in your diet, which helps your body absorb calcium. A few vitamin D-rich foods include milk, egg yolks, and fish.

red lips line

6…Stop Stains With Baking Soda

red_wine_spilled_on_white_carpet image

If your love of coffee, red wine, or other tooth-staining food and drink is leaving your pearly whites dim, try brushing baking soda on your teeth twice a month, just like you would toothpaste, then rinse away to help brighten your smile. If plain baking soda irritates your teeth or gums, you may want to try a toothpaste that contains baking soda or avoid it completely.

red lips line

7…Foods Can Stain or Brighten Teeth

woman_biting_into_strawberry image

There’s speculation that strawberries may have natural teeth-whitening properties. But it’s best to brush thoroughly after eating teeth-staining food like blueberries, coffee, and cigarettes. To help minimize discoloration, brush, then munch on apples, pears, carrots, or celery, all of which trigger tooth-bathing saliva, which helps keep your teeth bright.

red lips line

8…Regulate Your Acid Reflux

man_with_acid_reflux image

If you have acid reflux, you’ll want to get it under control to help preserve tooth enamel and oral health. Common foods and drinks that trigger reflux include chocolate; alcohol; caffeinated drinks like soda, coffee, and tea; garlic and onions; dairy; tomatoes; citrus fruits; mint; and spicy, fatty, or fried foods.

red lips line

9…Take Care of Your Tongue


Tackle bad breath every time you brush — take time to brush or scrape your tongue, too. Your tongue plays host to the bacteria that help cause bad breath, so giving it a scrub, or using a tongue scraper daily, can help reduce odor-causing compounds.

red lips line

10…Medication Can Cause Dry Mouth


Your mouth needs saliva to stay healthy, but hundreds of medications, like antidepressants, high blood pressure drugs, and antihistamines, can dry up saliva. Medication is the most common cause of dry mouth. To help keep your mouth moist, increase your fluid intake, ask your dentist about an artificial saliva product, or chew sugarless gum after a meal.

20 Bad Habits That Wreck Your Teeth

If we are aware of more things that are exposing our teeth to danger of dame & decay we should take notice & watch if we do them so a correction in out teeth maintenance can be made if necessary

woman teeth chewing on ice image

1…Chewing on Ice

It’s natural and sugar free, so you might think ice is harmless. But munching on hard, frozen cubes can chip or even crack your teeth. And if your mindless chomping irritates the soft tissue inside a tooth, regular toothaches may follow. Hot foods and cold foods may trigger quick, sharp jabs of pain or a lingering toothache. Next time you get the urge for ice, chew some sugarless gum instead.

red lips line

2…Playing Sports With No Mouth Guard

hockey player missing tooth image

Whether you play football, hockey, or any other contact sport, don’t get in the game without a mouth guard. This is a piece of molded plastic that protects the upper row of teeth. Without it, your teeth could get chipped or even knocked out when the action gets rough. Self-fitting mouth guards may be purchased at a store, or you can have one custom made by your dentist.

red lips line

3…Bedtime Bottles

baby with bottle in mouth image

It’s never too early to protect teeth. Giving a baby a bedtime bottle of juice, milk, or formula, can put new teeth on a path to decay. The baby may become used to falling asleep with the bottle in his or her mouth, bathing the teeth in sugars overnight. It’s best to keep bottles out of the crib.

red lips line

4…Tongue Piercings

pierced tongue image

Tongue piercings may be trendy, but biting down on the metal stud can crack a tooth. Lip piercings pose a similar risk. And when metal rubs against the gums, it can cause gum damage that may lead to tooth loss. The mouth is also a haven for bacteria, so piercings raise the risk of infections and sores. Bottom line, discuss the health risks with your dentist first.

red lips line

5…Grinding Teeth

grinding teeth image

Teeth grinding, or bruxism, can wear teeth down over time. It is most often caused by stress and sleeping habits. This makes it hard to control. Avoiding hard foods during the day can reduce pain and damage from this habit. Wearing a mouth guard at night can prevent the damage caused by grinding while sleeping.

red lips line

6…Cough Drops

cough dropp lolly assort image

Just because cough drops are sold in the medicine aisle doesn’t mean they’re healthy. Most are loaded with sugar. So after soothing your throat with a lozenge, be sure to brush well. Whether the sugar comes from a cough drop or a hard candy, it reacts with the sticky plaque that coats your teeth. Then bacteria in the plaque convert the sugar into an acid that eats away at tooth enamel. Hello, cavities.

red lips line

7…Gummy Candy

gummy bear candy image

All sugary treats promote tooth decay, but some candies are harder to bear. Gummies stick in the teeth, keeping the sugar and resulting acids in contact with your enamel for hours. If your day just isn’t the same without a gummy critter, pop a couple during a meal instead of as a separate snack. More saliva is produced during meals, which helps rinse away candy bits and acids.

red lips line

7…Sweet Soda

swetened soda bubbles image

Candy isn’t the only culprit when it comes to added sugar. Sodas can have up to 11 teaspoons of sugar per serving. To add insult to injury, sodas also contain phosphoric and citric acids, which eat away at tooth enamel. Diet soft drinks let you skip the sugar, but they may have even more acid in the form of the artificial sweeteners.

red lips line

8…Opening Stuff With Your Teeth

teeth being used to open package image

Opening bottle caps or plastic packaging with your teeth may be convenient, but this is one habit that makes dentists cringe. Using your teeth as tools can cause them to crack or chip. Instead, keep scissors and bottle openers handy. Bottom line, your teeth should only be used for eating.

red lips line

9…Sports Drinks

sports drinks bottles image

There’s no doubt a cold sports drink is refreshing after a good workout. But these drinks are usually high in sugar. Like soda or candy, sugary sports drinks create an acid attack on the enamel of your teeth. Drinking them frequently can lead to decay. A better way to stay hydrated at the gym is to chug sugar-free, calorie-free water.

red lips line

10…Fruit Juice

fruit juices in glasses image

Fruit juice is loaded with vitamins and antioxidants, but unfortunately most juices are also loaded with sugar. Some juices can have as much sugar per serving as soda. For example, there are only 10 more grams of sugar in orange soda than in orange juice. Fruits are naturally sweet, so look for juice that has no added sugar. You can also reduce the sugar content by diluting juice with some water.

red lips line

11…Potato Chips

potato chips image

The bacteria in plaque will also break down starchy foods into acid. This acid can attack the teeth for the next 20 minutes — even longer if the food is stuck between the teeth or you snack often. You might want to floss after eating potato chips or other starchy foods that tend to get stuck in the teeth.

red lips line

12…Constant Snacking

sunflower seeds image

Snacking produces less saliva than a meal, leaving food bits in your teeth for hours longer. Avoid snacking too frequently, and stick to snacks that are low in sugar and starch — for example, carrot sticks.

red lips line

13…Chewing on Pencils

pencil chewed end image

Do you ever chew on your pencil when concentrating on work or studies? Like crunching on ice, this habit can cause teeth to chip or crack. Sugarless gum is a better option when you feel the need to chew. It will trigger the flow of saliva, which can make teeth stronger and protect against enamel-eating acids.

red lips line

14…Drinking Coffee

Coffee’s dark color and acidity can cause yellowing of the teeth over time. Fortunately, it’s one of the easiest stains to treat with various whitening methods. Talk to your dentist if you’re concerned about discoloration of your teeth.

Cigarettes, as well as other tobacco products, can stain teeth and cause them to fall out as a result of gum disease. Tobacco can also cause cancer of the mouth, lips, and tongue. If you were looking for one more reason to quit, think of your smile.

16…Drinking Red Wine

The acids in wine eat away at tooth enamel, creating rough spots that make teeth more vulnerable to staining. Red wine also contains a deep pigment called chromogen and tannins, which help the color stick to the teeth. This combination makes it easy for the wine’s red color to stay with you long after your glass is empty.

17…Drinking White Wine

You might think sticking to white wine would spare your teeth. But the acids still weaken the enamel, leaving the teeth porous and vulnerable to staining from other beverages, such as coffee. Swishing with water after drinking or using toothpaste with a mild whitening agent can fight the staining effects of red and white wines.

19…Binge Eating

Binge eating often involves excessive amounts of sweets, which can lead to tooth decay. Binging and purging (bulimia nervosa) can do even more damage to dental health. The strong acids found in vomit can erode teeth, making them brittle and weak. These acids also cause bad breath. Bulimia can lead to a variety of serious health problems, so be sure to talk to your doctor if you have been purging.

No-drill dentistry stops decay, reducing need for fillings, says Sydney Uni study

Associate Professor Wendell Evans from the faculty of dentistry, Sydney University at Westmead.

Tooth decay occurs slowly enough to be stopped, even reversed, reducing the need for fillings by 80 per cent in high-risk patients, a new study by Sydney University says.

The results are good news for the estimated 15 per cent of Australians who avoid treatment because they have a phobia about going to the dentist

Knowing they wouldn’t face the drill was important to patients coping with the phobia, said Associate Professor Wendell Evans, lead investigator of the seven-year oral health study into “no-drill dentistry”.

He said the results signalled a need for Australian dentistry to move away from the traditional “fill and drill” approach.

“It’s unnecessary for patients to have fillings because they’re not required in many cases of dental decay,” he said.

For a long time, it was believed that tooth decay occurred rapidly and the best way to stop the rot was to remove it, even in earlier stages, and to fill the cavity.

“However, 50 years of research studies have shown that decay is not always progressive and develops more slowly than was previously believed.

“For example, it takes an average of four to eight years for decay to progress from the tooth’s outer layer [enamel] to the inner layer [dentine].

“That is plenty of time for the decay to be detected and treated before it becomes a cavity and requires a filling,” Professor Evans said.

“A tooth should only be drilled and filled where an actual hole in the tooth [cavity] is already evident,” he said.

The study was published in Community Dentistry and Oral Epidemiology on Monday.

Researchers compared more than 1000 patients at 22 dental practices in NSW and the ACT. Some were in areas with fluoridated water, some without.

Half were treated conventionally. The others were treated using the Caries Management System, a preventive approach used on teeth where decay has been detected but has yet to form a hole.

The new approach included:

▪ Application by dentists of high concentration fluoride varnish on teeth showing signs of early decay.

▪ Advice on how to brush teeth better.

▪ Restriction of between-meal snacks and beverages containing added sugar.

▪ Monitoring according to the level of risk.

After seven years, the need for fillings was reduced by 30 to 50 per cent in average patients using preventive care compared with patients treated with conventional methods.

High-risk patients – those who required as many as two fillings a year – had an 80 per cent reduction, Professor Evans said.

There was plenty of research to illustrate that fluoride and other preventive measures reduced decay, which hadn’t been translated into practice.

Dentists had became institutionalised to deal with decay by drilling and filling, he said.

He called for prevention to be introduced as a new area of specialisation for dentists so there was a career pathway.

The cost of the no-drill approach is about the same for most people, and a little more for high-risk patients.

Phobia of the dentist’s drill is so common that it stops people from visiting the dentist.

A new study by King’s College London in the British Dental Journal found an average of five talking therapy (cognitive behavioural therapy) visits was effective in reducing or eliminating fear.

Three-quarters of the group studied had a “dental phobia”, while the rest had a specific fear of one aspect of dentistry, such as injections or the drill.

Of all the patients, 79 went on to have dental treatment without the need for sedation, while 6 per cent had their dental treatment under sedation.

Eithne Irving, deputy chief executive of the Australian Dental Association, said: “Research such as this contributes greatly to the evidence base that underpins contemporary dental care in Australia and the ADA will be promoting these findings among its members.

“Professor Wendell is correct in saying that prevention is a key plank in the fight against dental disease and this is why the ADA continues its efforts on oral health promotion through activities such as Dental Health Week and community access to fluoridated water supplies.

“Preventive dentistry is the backbone of modern dental practice and this research will provide further evidence of the benefits of this approach for patients.

“At the end of the day, there is no substitute for patients having regular check-ups and practising good oral hygiene behaviours such as brushing twice daily, flossing once a day and reducing their exposure to sugary foods and drinks.

“Prevention is always better than a cure.”
