Latest technology For Regeneration of Broken Tooth

Researchers from the University of Alberta believe they have found a method of regrowing teeth and possibly bone that have been broken. The scientists use a miniaturized low-intensity pulsed ultrasound (LIPUS) system-on-a-chip which offers a non-invasive and novel way to stimulate jaw growth and dental tissue healing.

Dr. Tarak El-Bialy from the Faculty of Medicine and Dentistry and Dr. Jie Chen and Dr. Ying Tsui from the Faculty of Engineering developed a tiny wireless ultrasound transducer device that comfortably fits inside the patient’s mouth while packed in biocompatible materials. The device is mounted on an orthodontic or “braces” bracket or even a plastic removable crown. The team also designed an energy sensor that will ensure the LIPUS power is reaching the target area of the teeth roots within the bone.

Dr. Chen says “It’s very exciting because we have shown the results and actually have something you can touch and feel that will impact the health of people in Canada and throughout the world.” Chen works out of the Department of Electrical and Computer Engineering and the National Institute for Nanotechnology.

The technology has already been patented, and they hope they will have the system-on-a-chip finished to complete the miniaturized device by next year. El-Bialy says “If the root is broken, it can now be fixed. And because we can regrow the teeth root, a patient could have his own tooth rather than foreign objects in his mouth.”

The device is aimed at people experiencing dental root resorption, a common effect of mechanical or chemical injury to dental tissue caused by diseases and endocrine disturbances. The market potential in the US alone is 1.4 million.

The device was first tested on rabbits. After positive results the scientists moved onto humans and found similar results. They have also shown that LIPUS can improve jaw growth in cases with hemifacial microsomia, a congenital syndrome where one side of the child’s jaw or face is underdeveloped compared to the other “normal” side.

Usually these patients undergo many surgeries to improve their facial appearance. The work on human patients was presented at the World Federation of Orthodontics in Paris, September 2005.

Teeth Bonding & Dental Fillings

Teeth bonding can correct minor dental flaws in one quick and easy procedure. It is sometimes used instead of porcelain veneers. Today’s bonding is tooth colored and produces beautiful results. It can be used to fill small holes, seal and protect your teeth, and to correct cosmetic flaws.

What is bonding?
Bonding refers to the substance used and to the procedure itself. Bonding material is a tooth colored paste. Your cosmetic dentist applies the bonding and shapes it while it is still soft. It can be sculpted and more can be added until just the right shape is achieved. Then it is hardened with a special light.

What is bonding used for?
Bonding can be used to create small, tooth-colored fillings for cavities.

Cracks and tooth erosion can be covered and sealed. Cracks and erosion can cause pain and sensitivity, tooth decay, and discoloration. Bonding restores the beauty and comfort of your smile, while protecting your teeth from further damage.

Bonding can be used to cover correct the look of small chips. Small gaps between your teeth can be filled by building up the surrounding teeth to close the gap.

The look of crooked and misshapen teeth can be corrected with bonding, by sculpting a new shape onto your teeth. Discoloration that is resistant to whitening can be covered.

Dental bonding vs. porcelain veneers
Dental bonding and porcelain veneers can be used to correct many of the same problems. There are advantages and disadvantages to choosing bonding over veneers.

The advantages of bonding include:
Bonding gives you faster results than veneers; bonding only requires one visit, veneers require two.
Bonding is less expensive than veneers.
Sometimes, bonding can be used to build up a larger portion of your tooth than veneers.

There are also some disadvantages to bonding:
Your bonding will match the color of your natural teeth and restore the beauty of your teeth, but it is not quite as beautiful and natural looking as veneers.
Bonding is not as stain resistant as veneers, so you have to be more careful about what you eat and drink to minimize discoloration over time, just like you do with your natural tooth enamel.
At home you will care for your teeth just like you always have with bonding, but when you have your teeth professionally cleaned you will need to see a hygienist who has experience with bonding or your bonding could be damaged.

Fillings:
Dental bonding can be used to create fillings for small holes in your teeth in one quick office visit. For larger areas of decay, your cosmetic dentist may recommend porcelain inlays or onlays. Inlays and onlays are created in a lab, so they require two office visits. The results, however are beautiful, blend seamlessly with your tooth, and strengthen your tooth.

FAQ's & Guideliness For Dental Crowns

Dental crowns can provide you with a great option for repairing damage done to your teeth. The following questions are commonly asked to cosmetic dentists by patients at their initial dental crown consultation:

What are dental crowns?
A dental crown, also known as a dental cap, is used to cover a damaged tooth and restore the tooth's strength and durability. Dental crowns cover the entire portion of the tooth visible above the gum line. This is different from a filling which only covers a portion of the visible part of a tooth.

Why would I need a dental crown?
There are many reasons why a dentist would recommend a crown including:

• Cracked teeth
• Fractured teeth
• An anchor is needed for a dental bridge to replace a missing tooth
• To cover a tooth that has had a root canal
• Fragile teeth
• Cosmetic purposes

A crown can fix a tooth that is misshapen or discolored. If you have been unhappy about the way a tooth looks, then a crown could be the answer to your problem.

How does a dentist make a dental crown?
A dentist creates a dental crown over the course of two dental appointments. During the first appointment, he will remove most of the outside surface of the tooth which will later be replaced by the crown. This is known as shaping the tooth. Once the tooth is shaped, the dentist will take several impressions of the tooth and other areas of the mouth. These impressions are sent to a dental technician who uses them to make a perfect fitting permanent crown. At the end of your first appointment, the dentist will attach a temporary crown to your tooth. During the second appointment, the dentist will attach the permanent crown to your tooth.

Is it painful to get a dental crown?
Getting a crown is a relatively painless procedure. The dentist uses a local anesthetic to numb the areas of the mouth being treated.

What are the different types of crowns?
There are three different types of crowns. They are:

• Gold Crown
• Porcelain Crown
• Porcelain-Fused-to-Metal Crown

Which crown is right for me?
This is a question for your dentist to answer. When you schedule a consultation visit, your dentist will discuss the various costs associated with a crown, the best type of crown for you, and also financing options.

Enamel Stripping & Teeth Discoloration

Latest Dental News: Enamel Stripping

Some amount of dulling and darkening of your teeth is just a natural part of aging. What we eat and drink and how we care for our teeth will affect how much staining and discoloration occurs on the outside of our teeth. Other factors, some beyond our control, can cause teeth to stain on the inside. Most staining can be corrected with tooth whitening. Stubborn, resistant discoloration can be covered with other procedures, giving you beautiful, white teeth again.

Aging:
As we age, the enamel of our teeth thins. When the enamel thins the dentin shows through. Dentin is yellow and as it becomes more visible your teeth lose their bright whiteness. Brushing and good oral hygiene cannot stop the dulling of your teeth caused by aging. Tooth whitening can reach and lighten the dentin.

Darkening on the outside of your teeth:
Staining on the outside of your teeth is called extrinsic staining. This is the type of darkening that you have the most control over. Your personal habits play a large role in extrinsic staining, but are not the only factor.

Proper brushing and flossing will minimize this type of staining. However, that doesn’t mean you should go crazy with aggressive brushing and using abrasive products. If you damage your tooth enamel your teeth will stain more easily.

Obviously, what you put in your mouth can stain your teeth. Staining foods and beverages include dark berries, coffee, tea, sodas, and red wine. Smoking and smokeless tobacco use will also stain your teeth.

Dental damage such as chipped teeth and tooth erosion leave areas unprotected by tooth enamel and they can darken quickly. Tooth erosion can be caused by many things including drinking sodas. It is common in swimmers due to excessive exposure to chlorine.

Metal (silver amalgam) fillings can become tarnished and stain your teeth. They can be replaced with beautiful, tooth-colored fillings.

Darkening on the inside of your teeth:
When your teeth become dark on the inside it is called intrinsic staining. This typically starts in childhood and is beyond your control. The most common cause of intrinsic staining is tetracycline use while your teeth were developing. Tetracycline is a very common antibiotic.

Intrinsic staining:
Staining inside of your teeth is called intrinsic staining. Intrinsic staining is very resistant to whitening. Your cosmetic dentist can determine if your teeth will respond to tooth whitening, and if not, he can recommend alternatives. Even if you have dark intrinsic staining, you can still have a beautiful, white smile.

If you were exposed to excessive fluoride while your teeth were forming you may have white fleck and/or brown stains in your teeth due to dental fluorosis. Public water supplies often have added fluoride. You can help protect your children from dental fluorosis and the health risks of excessive fluoride by giving them bottled water or installing a high quality water filter in your home and having use fluoride-free toothpaste until they are at least three years old.

An injury to a tooth can cause it to darken. This can happen very slowly after the trauma occurs.

Some intrinsic stains respond to whitening, but in most cases you will need to cover the stained teeth with porcelain veneers or tooth bonding. Even the toughest stains can be covered giving you beautiful, white teeth again.

Tooth Ache & Anti-Snoring Treatment

Latest Dental News: Anti-Snoring Treatment

Anyone who has ever suffered from a toothache knows how painful it can be. Does it seem that for some reason, toothaches most often strike on a weekend or late at night when you can’t get in touch with your dentist? What can be done to ease this pain when your dentist isn’t available?

Most often, tooth decay, abscesses, impacted teeth, gum problems, or sometimes something as simple as a piece of food being lodged between the teeth can cause toothaches. Some diseases not associated with the mouth can also cause toothaches, such as heart disease, sinuses, and ear infections. Sometimes toothaches can simply be due to temporary sensitivity. Toothache pain can range from mild to severe. It is always a good idea to rinse your mouth with water and gently floss, in case a food particle is the culprit. In the event that this does not work, there are some other remedies to try to relieve your ache until you can consult a professional.

Over-the-counter pain medication such as aspirin or Tylenol is available for short-term pain relief, as are antiseptics and gels. These things will numb the area. Your pharmacist can recommend different brands and explain what they do.

Through the years, home remedies for toothaches have sprung up. These remedies can be either medicinal or herbal in nature. One of the most popular toothache remedies is clove oil. You can either use the liquid form or the actual clove. Rubbing clove oil on the tooth is believed to relieve the pain from a toothache. Clove oil contains eugenol, which is a natural pain killer and an antibacterial substance.

Another remedy for toothaches is to mix lime juice and asafoetida powder. Asafoetida is a spice used in Indian cooking. Soak a cotton ball in this mixture and rub it on your tooth and gum. This will help to ease your pain. You can also try adding 1 tbsp of salt to ½ cup of boiling water. Put this combination in your mouth, as hot as you can bear it. Then swish it around the problem area. You can also gargle with Listerine Antiseptic, as this has been known to bring relief as well.

Another home remedy is to pour a few drops of vanilla extract on the tooth, as this has been known to ease the pain. You can even crush a clove of fresh garlic and mix it with peanut butter and apply this to the tooth. Does this sound disgusting? Maybe – but it has been known to help. Chewing on ice on the side of the mouth in pain will help as well.

If the above remedies work only temporarily, a sure fire remedy is to visit your dentist. In the line of prevention, the dental community recommends brushing twice daily, flossing at least once a day, and making an appointment for a dental cleaning every six months.

Oral Cancer & Smoking

Latest Dental News: Smoking and Your Oral Health

Typically, oral cancer has been associated with tobacco and alcohol use; however, people who don’t smoke or drink excessively are also susceptible. Men are twice as likely as women to get oral cancer; in fact, an estimated 19,000 men are diagnosed with oral cancer each year. Adding to this, research suggests that men who have been diagnosed with the human papillomavirus (HPV) are at a higher risk for getting oral cancer. Oral cancer is a serious illness, and its treatment and diagnosis deserve serious attention.

Because there is currently no cure for HPV, many in the medical community are now promoting the vaccine Gardasil to prevent the acquisition of the sexually transmitted disease (and, by extension, oral cancer) in men and boys. Although Gardasil may help address the problem, it is critical that men receive proper dental care to help screen for oral cancer.

Oral Screenings:
As with other types of cancer, early detection is critical in beating oral cancer. Fortunately, breakthroughs in technology allow for faster and more accurate detection of suspicious tissue than ever before.

Good oral screenings includes the following:

• Regular check-ups – During a routine examination, your dentist will inspect your mouth for lesions, discolorations, or other abnormalities.
• Adjunctive screening – Today, many dentists use technology such as ViziLite Plus to better detect soft tissue abnormalities. During an adjunctive screening, your dentist will dim the lights and use a special light to inspect the inside of your mouth. These screenings are completely painless, and they can alert your dentist to abnormalities that might not be readily visible to the naked eye.

What to Watch For:
During your appointment, you might learn what warning signs to look for at home; by empowering patients to self-examine, dentists help ensure that oral cancer is caught early.

If you notice any of the following, call a dentist right away:

• White, red, or otherwise discolored spots in the mouth
• Sores in or around the mouth that do not heal
• Excessive and repeated bleeding in the mouth
• Pain or numbness in the mouth area

The key to successfully fighting oral cancer is early diagnosis. All adults - especially those in high-risk groups - should be sure to visit the dentist regularly and be aware of potential warning signs.

Latest Dental News: Home Tray Teeth Whitening

There was a time when if you wanted whiter teeth, it seemed that the only option was to go to the dentist and have the teeth bleached. Now there are numerous tooth whitening products on the market that you can use at home. But both of these options involve using potentially dangerous chemicals, and they can even make teeth very sensitive, replacing one problem with another more serious one.

But there is good news. There are many ways in which we can brighten our teeth naturally. By using some preventive measures and making treatments out of herbs and things we can find around the house or at the grocery store, we can make our pearly whites whiter.

Here are the tips:

• As always, brushing and flossing regularly is the most important thing we can do for our teeth. It helps prevent cavities and fight plaque and tartar, and it also reduces staining. Brush after every meal if possible. If you don't have a toothbrush handy, rinsing your mouth well is better than nothing.
• Avoid using too much fluoride. Although fluoride is included in toothpastes and water supplies, too much of it can discolor your teeth.
• Avoid tobacco use, and go easy on the coffee and tea. These are three of the most common culprits of tooth staining.
• Cola, wine, and even certain fruits and vegetables can also stain teeth. That doesn't mean we have to stop eating fruits and vegetables, just that we should take special care to brush well after eating some of them.
• Some fruits are excellent tooth whiteners. Strawberries, for example, can be rubbed directly on teeth or mashed up and brushed on. The inside of an orange peel is also great for whitening. You can rub it directly on your teeth, or make a paste of dried orange peel and ground bay leaves to brush on. A mixture of lemon juice and salt also works well.
• Use baking soda. Many of the toothpastes on the market include baking soda in their ingredients because it is so effective. But you don't have to buy special toothpaste. You can mix baking soda with a dash of salt and add a little vinegar to make a homemade tooth whitener.
• Take care when choosing a mouthwash. Most have alcohol in them, and some even have ingredients such as chlorhexidine that can discolor teeth. Herbal antibacterial mouthwashes are available that kill germs and freshen breath without harmful chemicals.
• Whitening your teeth does not have to be expensive, and you don't have to use harsh chemicals. By using preventive measures and natural remedies, you can make your smile brighter without harming your teeth in other ways.

Difference Between Porcelain Veneers & Teeth Whitening

Latest Dental News: Vaccum Formed Retainer

Porcelain veneers are custom-crafted shells of ceramic material applied over the front surface of a tooth. They cover worn enamel, uneven alignment or sizing, minor chips and cracks, and small gaps.

The bright, white, beautifully aligned smile that can be achieved with porcelain veneers has made the procedure very popular, particularly since today’s advanced materials offer high quality porcelain which gives a natural look.

Tooth whitening is also a popular option, as you can tell by looking at all the tooth-whitening products available in stores. A professional whitening procedure will give you more consistent and dramatic results than any of those products. You can have it done in the cosmetic dentist’s office in a little over an hour. Or you can take home a professional do-it-yourself kit. Both methods give equally excellent results.

Are Veneers and Whitening Mutually Exclusive?

No. You can do both procedures. Veneers are placed only on front teeth. If you had veneers done and left the rest of your teeth to become yellow and stained, your mouth would be multicolored and your dental beauty reduced. Side teeth and even back teeth become visible when you laugh or yawn, even if they are not visible when you smile.

For individuals who experience mild tooth discoloration, over-the-counter teeth whitening may be an effective, although temporary, option. When discoloration is more severe, in-office laser whitening, which uses a higher concentration of peroxide, is more effective and long lasting. Those with severely dull, discolored, chipped or misaligned teeth find that porcelain veneers are the best solution overall, since tooth whitening can only solve the issue of discoloration.

Veneers offer additional benefits over tooth whitening, including long-lasting results, durability, and enhancement of the facial structure of older individuals who may have a sunken facial appearance due to dental issues. Teeth whitening is a simple process taking less than an hour to complete. Veneers require a greater commitment of time and cost, but are well worth it for those individuals who are good candidates for the procedure. Most cosmetic dentists offer affordable financing to suit a variety of budgets.

Causes & Prevention for Tooth Discoloration

Latest Dental News: Smoking and Your Oral Health

Many people have discolored teeth and it makes then very self-conscious about their smile. While slight discoloration is expected as we age, there are some things that can speed up the darkening of our teeth:

• Due to the extremely high acid content in soft drinks, the deterioration of the enamel on your teeth is sped up.
• Drinking red wine, coffee and tea. Any dark liquids have the potential to stain your teeth. Heat from tea and coffee causes are small fractures in your tooth enamel.
• Using tobacco products. Smoking will cause a yellowish build up on the teeth. These kinds of stains are typically more difficult to remove and will take longer to lighten using whitening treatments.

• Certain medications. The two most common medications that have been shown to darken teeth are tetracycline and minocycline.
• Too much fluoride, whether it be water or different fluoride based products. Fluoride discoloration typically happens during the development stage of the tooth.
• Any sort of of trauma to your teeth can lead to a discoloration. This happens because there is a tiny hemorrhage inside the tooth and the blood that is forced in there will make the tooth appear darker.

Over-the-Counter Tooth Whitening

There are many tooth whitening products available on the market today. However, they may not be effective or even damage your teeth. Products that may whiten your teeth include:

• Chewing gum doesn’t have much of a bleaching agent, so whitening results are very minor. However, activating the saliva may help some.

• Whitening toothpastes should only be used in moderation due to the abrasives they contain. Long use of those abrasive materials will actually wear down the tooth enamel.

• At-home tooth bleaching kits can provide decent results, but they can be difficult and messy to use. Also, since they typically don’t provide dental dams, ingestion of the bleach could upset people’s stomachs.

Professional Teeth Whitening

While any of the products above have the capability of providing results, but professional bleaching services are a better choice because:

• The bleaching agents are much stronger in the professional products which will lead to faster and better results.
• They are safer to use because your dentist will use the proper methods to ensure you don’t ingest the bleach, unlike over-the-counter products.
• Your dentist can assess you condition and your expectations and help you make the right procedure for your needs.

Dental Bonding and Porcelain Veneers

If your staining is too severe, it is important to realize that tooth bleaching might not give you the results you desire. However, there are still a couple options to gaining the beautiful, white smile you’ve always wanted:

• Tooth bonding
• Porcelain veneers

Dental bonding is a procedure in which a type of resin is sculpted and adhered to your teeth. This product is extremely strong and durable and it is indistinguishable from your natural tooth enamel. This resin is essentially replacing the enamel on your tooth, which will hide stubborn stains. Tooth bonding is quick and can typically be completed in one office visit.

Porcelain veneers are another option to hide stubborn stains. The veneers are very thin layers of porcelain that are affixed to the tooth. Your natural tooth is carefully filed down in order for the veneers to properly adhere to the tooth. This option will take slightly longer and involve a couple of trips to the office.
