Smart Braces Take The Bite Out Of Conventional Orthodontia

One could say that donning a mouthful of braces isn’t the most pleasant of experiences. Researchers at King Abdullah University of Science & Technology (KAUST) are looking to revamp the process with smart, 3D-printed braces running on nontoxic batteries and light.

The new system centers around one lithium-ion (Li-ion) battery and two near-infrared light-emitting diodes (LEDs) on each tooth. This tech is situated on a 3D-printed, semitransparent dental strip that is flexible enough to remove in order to recharge.

The Li-ion batteries supply the power to the LEDs, turning them on and off. The rate of light therapy depends on specific programming by the dentist, determined by the individual needs of each tooth. Phototherapy has provided considerable benefits in orthodontic treatment, reducing cost, time, and promoting bone regeneration.

“We started embedding flexible LEDs inside 3D-printed braces, but they needed a reliable power supply,” says Muhammad Hussain, leader of the research, along with Ph.D. student Arwa Kutbee.

“After the incidents with the Samsung Galaxy 7 batteries exploding, we realized that traditional batteries in their current form and encapsulation don’t serve our purpose. So we redesigned the state-of-the-art lithium-ion battery technology into a flexible battery, followed by biosafe encapsulation within the braces to make a smart dental brace,” Hussain adds.

The battery redesign, mentioned by Hussain, was accomplished through dry-etching. This technique thinned the battery and increased flexibility by removing the silicon that is usually situated on its back. The final dimensions leveled at 2.25 mm x 1.7 mm.

Materials made of soft, biocompatible polymers surrounded the power supply to halt leakage. The outer coating was vital for the device to remain safe for human use.

The KAUST team sees these initial findings as a preliminary step that serves as a proof-of-concept prototype. Clinical trials are next on the to-do list.

The full details of the research can be found in an article published in the journal Flexible Electronics.

Amazing New Paste From Japan Repairs Cavities Without Drilling

An incredible breakthrough treatment for tooth decay is set to be unveiled shortly: A team of researchers in Japan led by Kazue Yamagishi, D.M.D. have come up with a special paste that regenerates the tooth enamel, causing teeth to self-repair. This is an astonishing discovery.

Did you know that 60% of dental therapy is said to be a retreatment of teeth that have already been treated? This is because dental filling materials such as resin or metal alloy are totally different from a tooth in composition and structure, and those differences cause tooth decay at the point where the two materials make contact.

Remineralization of teeth is a subject plagued by controversy, with “orthodox” dental theory holding that once teeth are decayed, there is simply no going back. But has this ever struck you as strange? If your skin or bones are damaged, they grow back. Why not teeth? Why is this “impossible”? Alternative dental theory, such as that propounded by Dr. Westin A. Price, maintains that the problem with our teeth is actually caused by modern agriculture, which does not provide the body with the level of minerals that are needed to prevent decay or even for teeth to heal. Dr. Price examined the skulls of very ancient tribal people and found that they had excellent and even perfect dental health, despite living in an era before toothpaste, toothbrushes or dental fillings existed!

However, the “official position” on whether tooth enamel can regenerate “naturally” may soon be completely irrelevant, thanks to the work of Kazue Yamagishi – whose synthetic enamel treatment will (according to his website) be available to the public in 2016. He states on his website “We have succeeded in developing such therapy of dreams”.Curiously, the method makes perfect sense: Regrow the tooth using the exact crystalline minerals a tooth is made from, rather than attempting to patch it with another substance.

Enamel is the outer layer of the human tooth. It is approximately 1 to 1.5mm thick and composed of hydroxyapatite (HAP) crystals. Acid-forming bacteria in the mouth typically damage this enamel gradually over time and this effect is of course accelerated by poor dental hygiene, which allows the bacteria to grow in greater numbers. The new paste of Dr. Yamagishi “grows HAP crystals, which are exactly like those in natural enamel, at the affected site within 15 min”. The team reported their exact methods (including listing the exact substances used) in a scientific paper [3] and reported that the new enamel, when examined under a high power microscope, grew continuous crystals, with no discontinuous boundary being observed.

The treatment is currently in the clinical trial stage in Japan, but no trials are scheduled in EU or USA yet. Another great reason to visit Japan… but let’s show our support for introducing these possibilities to the rest of the world.

Note that this paste will require a dentist’s application and is reported unsuitable for home use due to the care which must be taken for the chemicals not to touch the gums at all. Also it is reported to work best on “microcaries” – the first stage of dental decay. However it really does seem that this treatment could prevent decay from ever getting hold and even bring us to the point where with proper treatment, tooth decay really becomes a thing of the past!

Another interesting positive effect of the proposed new treatment is that the treated tooth will become whiter than a normal tooth owing to the purity of the apatite minerals used – so it will be a whitening treatment into the bargain. [4]

Neanderthal tooth plaque reveals paleo-diet & the use of aspirin

ANCIENT DNA from dental plaque is revealing intriguing new information about Neanderthals including specific menu items in their diet like woolly rhinoceros and wild mushrooms as well as their use of plant-based medicine to cope with pain and illness.

Australian-led researchers have genetically analysed plaque from 48,000-year-old Neanderthal remains from Spain and 36,000-year-old remains from Belgium. The plaque, material that forms on and between teeth, contained food particles as well as microbes from the mouth as well as respiratory and gastrointestinal tracts.

At Belgium’s Spy Cave site, which at the time was a hilly grassy environment home to big game, the Neanderthal diet was meat-based with woolly rhinoceros and wild sheep, along with wild mushrooms.

Some 12,000 years earlier, at Spain’s El Sidron Cave site, which was a densely forested environment likely lacking large animals, the diet was wild mushrooms, pine nuts, moss and tree bark, with no sign of meat.

The two populations apparently lived different lifestyles shaped by their environments, the researchers said.

The researchers found that an adolescent male from the Spanish site had a painful abscess and an intestinal parasite that causes severe diarrhoea. The plaque DNA showed he had consumed poplar bark, containing the painkilling active ingredient of aspirin, and a natural antibiotic mould.

“This study really gives us a glimpse of what was in a Neanderthal’s medicine cabinet,” said paleomicrobiologist Laura Weyrich of Australia’s University of Adelaide, lead author of the study published in the journal Nature.

Analysis of Neanderthal tooth plaque hints at what they may have eaten – and kisses

The findings added to the growing body of knowledge about Neanderthals, the closest extinct relative of our species, Homo Sapiens, and further debunked the outdated notion of them as humankind’s dimwitted cousins.

“I definitely believe our research suggests Neanderthals were highly capable, intelligent, likely friendly beings. We really need to rewrite the history books about their ‘caveman-like’ behaviours. They were very human-like behaviours,” Weyrich said.

The robust, large-browed Neanderthals prospered across Europe and Asia from about 350,000 years ago until going extinct roughly 35,000 years ago after our species, which first appeared in Africa 200,000 years ago, established itself in regions where Neanderthals lived.

Scientists say Neanderthals were intelligent, with complex hunting methods, probable use of spoken language and symbolic objects, and sophisticated fire usage.

The researchers also reconstructed the genome of a 48,000-year-old oral bacterium from one of the Neanderthals.

“This is the oldest microbial genome to date, by about 43,000 years,” Weyrich said.

1/14

What’s the first thing you should do for peeling or chapped lips?

  • a-Lick them to keep them moist
  • b-Apply lip balm
  • c-Gently peel off flakes
  • Correct! You answered: Apply lip balm

Balms — even if they’re inexpensive or very basic — are key for rehydrating dry lips and locking in moisture. Licking, however, makes it worse. Choose one with sunscreen, SPF 15 or higher, since sun exposure can cause chapped lips or make them worse.

        red lips line

2/14

Which food has the same ingredient as many lip-plumping glosses?

  • a-Balsamic vinaigrette
  • b-Salsa
  • c-Strawberry jam
    Correct! You answered:Salsa

    Capsaicin, the compound that gives heat to hot peppers, is used in many lip-plumping glosses. Capsaicin — or other ingredients like cinnamon, wintergreen, and menthol — irritates the lips, increasing blood flow. The idea is that the extra blood will swell the lips, but most experts say the effect is minimal.

    To get a plumper look with makeup, put a dot of silver or gold lip gloss or shimmery eye shadow in the middle of your upper and lower lips. It’ll create the appearance of a puffier pout.

    red lips line

    3/14

    Which of these is the better treatment for cracked or chapped lips?

    • a-A petroleum-jelly-like balm
    • b-A classic, waxy stick
      • Correct! You answered: A petroleum-jelly-like balm

      Balms and sticks with petrolatum and other sealing agents like shea butter maintain moisture inside your skin better than wax does. But what may help heal the lips even faster is treating them with an extremely moisturizing lip or face cream that will soak into the skin and then sealing the moisture in with a balm. Look for creams with antioxidants or hyaluronic acid.

      red lips line

      4/14

      Sheer lipsticks are better than matte lipsticks for women with dry lips.

      • a-True
      • b-False
      • Correct! You answered: True

      It used to be that matte lipsticks contained few oils and could cake and flake on drier lips. But these days, the lipsticks of most good makeup lines include either emollients like shea butter or types of silicone that keep lips moist.

      red lips line

      5/14

      Women with braces shouldn’t wear lipstick, or at least not bright or shiny colors.

      • a-True
      • b-False
      • Correct! You answered: False

      Going withoutlip color will bring full attention to your mouth, so the only thing you’ll notice is the braces, says LA aesthetician LeAine Dehmer. The trick is to bring attention to the lips themselves. To do that, avoid dark tones. But go ahead and add shine or a gentle sparkle, she says. It may boost your confidence.

      A leading orthodontist notes that bright color also brings the focus to your mouth. But some women with braces like people to notice, says Dr. Gayle Glenn.

      If you have ceramic braces, a lip stain or long-lasting formula lipstick may be less likely to smudge and get color on your brackets, she says.

      red lips line

      Is it your imagination, or are your mustache hairs getting darker with age?

      • a-Your imagination
      • b-They’re getting darker
      • Correct! You answered: They’re getting darker

      Many women complain as they age that formerly fine or light hairs on their upper lip seem to get darker or coarser as they get older. It’s a real phenomenon that can be due to normal hormonal fluctuations.

      Excessive new hair growth, however, should be checked out by a doctor.

      red lips line

      7/14

      Which of these are good for your health, but may be bad for your teeth?

      • a-Citrus fruits
      • b-Red wine
      • c-Both
      • Correct! You answered: Both

      Despite being packed with heart-healthy polyphenols, red wine can stain teeth. It’s also acidic, as are foods like citrus, and highly acidic foods and drinks can erode enamel.

      red lips line

      8/14

      What’s the best thing to do right after eating an orange?

      • a-Give your teeth a quick brush
      • b-Chew some gum
      • Correct! You answered: Chew gum

      Acidic foods and drinks like citrus and alcohol temporarily soften enamel — so if you brush right after consuming them, you can actually wipe away some of your enamel. The best thing to do is chew some sugarless gum with xylitol, which helps counteract the acid.

      Eating some cheese or drinking milk will do the same thing. (FYI, brushing an hour or two later is fine.)

      red lips line

      9/14

      Aside from smoking, what’s the top cause of fine lines above the lip?

      • a-Drinking from bottles/straws
      • b-Sleeping on your stomach/face
      • Correct! You answered: Drinking from bottles/straws

      Experts have long noticed that women who smoke tend to get very pronounced fine lines around the mouth, partially from constant contraction of the muscles in that area. But pursing your lips to sip from a straw, sports bottle, or reusable coffee cup requires the same kind of muscle contraction.

      To reduce this effect, sip straws from the sides of your mouth, and pay attention to pursing less while sipping from other cups.

      red lips line

      10/14

      Botox shots are the best way to treat lines around the lips.

      • a-True
      • b-False
      • Correct! You answered: False

      Botulinum toxin injections such as Botox and Dysport do work, but they’re not the only fix. Botulinum toxin relaxes muscles around the mouth, smoothing the appearance of lines by reducing the ability to pout the lips temporarily.

      Fillers can be used to plump out the area, smoothing lines, and laser resurfacing may smooth things by strengthening collagen under skin.

      As for over-the-counter cures, anti-aging creams with peptides or retinoids specifically formulated for the areas around the mouth may help.

      red lips line

      11/14

      What can help keep lipstick from bleeding into lip lines?

      • a-Eyebrow pencil
      • b-Face powder
      • c-Cream blush
      • Correct! You answered: Face powder

      The latest lipsticks don’t feather as much as those from years ago — but if yours still does, try this makeup artist strategy for filling in lines:

      Apply a moisturizing cream around the mouth and let it soak in; lightly dust the upper lip area with a fine face powder, then press into lip line with finger tip. Line lips with lip pencil, then apply your favorite lipstick.

      red lips line

      • 12/14

        Which of these toiletries can help keep lipstick from flaking?

        • a-Toothbrush
        • b-Dental floss
        • c-Mouthwash

        Correct! You answered: Toothbrush

        Exfoliating lips — sloughing away dead skin — creates a smooth surface for lipsticks and glosses. You don’t need a fancy product to do it; just run your toothbrush over your lips to quickly swipe away flakes.

      red lips line

      13/14

      You’re most likely to get a good result from at-home whitening if your teeth are

      • a-Yellowish
      • b-Grayish
      • Correct! You answered: Yellowish

      People with yellow tones to their teeth are likely to respond best to in-office or at-home tooth-whitening gels and strips. But grayish teeth might not bleach out at all, especially if the teeth have a bit of a translucent look. That’s likely caused by age or by thin enamel. In those cases, a cosmetic dentist may recommend veneers, bonding, or crowns.

      red lips line

      14/14

      Which of these at-home tooth-whitening products may take the longest to work?

      • a-Whitening rinses
      • b-Whitening strips
      • c-Whitening trays + gel
      • Correct! You answered: Whitening rinses

      Whitening mouthwashes that include the bleaching agent hydrogen peroxide are on teeth for a short time, rather than 30 minutes or more like strips and trays. So any effect they have may take longer.

Top ToothTips for Beautiful Teeth and Gums-2nd posting

1…Axe the Dental Visit Anxiety

woman_wearing_headphones_at_dentist image www.perfectwhiteteeth.net

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 www.perfectwhiteteeth.net

Flossing first makes 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, angle bristles 45-degree at the gum line, then brush gently, moving the brush back and forth. Then, rinse with an antibacterial mouthwash to help get rid of any leftover plaque.

red lips line

3…Go Easy With Toothpicks

man_picking_teeth_with_toothpick image www.perfectwhiteteeth.net

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 www.perfectwhiteteeth.net

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 www.perfectwhiteteeth.net

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 www.perfectwhiteteeth.net

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 www.perfectwhiteteeth.net

There’s been speculation that strawberries may have natural teeth-whitening properties, but so far, it hasn’t been proven. 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 www.perfetwhiteteeth.net

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

woman_using_tongue_scraper image www.perfectwhiteteeth.net

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

woman_with_dry_mouth image www.perfectwhiteteeth.net

medication & tooth health

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.

DENTISTS WARN AGAINST USING CHEAP MOUTHGUARDS AFTER THIS GIRL WAS SEVERELY INJURED IN HOCKEY GAME

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

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 teeth.net

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 www.perfectwhiteteeth.net

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 www.perfectwhiteteeth.net

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 www.perfectwhiteteeth.net

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 www.perfectwhiteteeth.net

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

aacd_rf_photo_of_fillings_in_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 www.perfectwhiteteeth.net

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 www.perfectwhite3teeth.net

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 www.perfectwhiteteeth.net

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 www.perfectwhiteteeth.net

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 www.perfectwhiteteeth.net

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 www.perfectwhiteteeth.net

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 www.perfectwhiteteeth.net

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.

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

blizzident-teeth-0

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.

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.

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

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.

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

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.
