IfYoureOlderbeontheLookoutforRootCavities

Tooth decay is a destructive oral disease, which along with periodontal (gum) disease is most responsible for tooth loss. And as you age, your disease risk goes up.

One form of decay older people often experience is root cavities. Unlike those occurring in the visible crown, root cavities often occur below the gum line and are especially destructive to tooth structure.

That's because, unlike the crown protected by ultra-hard enamel, the roots are covered by a thin, mineralized material called cementum. Although cementum offers some protection, it can't compare with the decay-resistant capacity of enamel.

The roots also depend on gum coverage for protection. But unfortunately, the gums can shrink back or recede, usually due to gum disease or over-aggressive brushing, and expose some of the root surface. With only the cementum to protect them, the roots can become highly susceptible to decay. If a cavity forms here, it can rapidly advance into the tooth's interior, the pulp, weakening the tooth and increasing its risk of loss.

To stop the decay, we must treat root cavities much like we do with crown cavities: by removing any decayed structure and then filling the cavity. But root cavities are often more difficult to access depending on how far below the gum line they extend. We may need to perform minor gum surgery to expose the cavity to treat it.

But as with any form of tooth decay, the best strategy is to prevent root cavities in the first place. Your first line of defense is a daily hygiene habit of brushing and flossing to remove dental plaque, the main cause for tooth decay. You should also visit your dentist at least twice a year (or more, if recommended) for more thorough cleanings and checkups. Your dentist can also recommend or prescribe preventive rinses, or apply fluoride to at-risk tooth surfaces to strengthen them.

You should also be on the lookout for any signs of gum disease. If you see swollen, reddened or bleeding gums, see your dentist as soon as possible. Stopping possible gum recession will further reduce your risk of root cavities.

If you would like more information on the prevention and treatment of tooth decay, please contact us or schedule an appointment for a consultation.

DontLetSummerHeatIncreaseYourRiskofDentalDisease

In many parts of the country, summer is often a synonym for "blast furnace" and can be downright hot and miserable. If you find yourself in such a climate, it's imperative that you drink plenty of water to beat both the heat and heat-related injuries. Your teeth and gums are another reason to keep hydrated during those hot summer months.

Your body needs water to produce all that saliva swishing around in your mouth. When you have less water available in your system, the production of this important bodily fluid can go down—and this can increase your risk of dental disease. That's because saliva performs a number of tasks that enhance dental health. It helps rinse the mouth of excess food particles after eating that could become a prime food source for disease-causing bacteria. It also contains antibodies that serve as the first line of defense against harmful microorganisms entering through the mouth.

Perhaps saliva's most important role, though, is protecting and strengthening enamel, the teeth's outer "armor" against disease. Although the strongest substance in the body, enamel has one principal foe: oral acid. If the mouth's normally neutral pH becomes too acidic, the minerals in enamel begin to soften and dissolve. In response, saliva neutralizes acid and re-mineralizes softened enamel.

Without a healthy salivary flow protecting the mouth in these different ways, the teeth and gums are vulnerable to assault from bacteria and acid. As they gain the upper hand, the risk for tooth decay or periodontal (gum) disease can skyrocket. Keeping yourself adequately hydrated ensures your body can produce an ample flow of saliva.

By the way, summer heat isn't the only cause for reduced saliva: Certain prescription medications may also interfere with its production. Chemotherapy and radiation, if targeting cancer near the head or neck, can damage salivary glands and impact flow as well.

If you have reduced saliva from medication you're taking, talk to your doctor about switching to an alternative prescription that doesn't affect saliva production. If you're undergoing cancer treatment, be extra vigilant about your oral hygiene practice and regular dental visits. And as with summer heat, be sure you're drinking plenty of water to help offset these other effects.

Even when it's hot, summertime should be a time for fun and relaxation. Don't let the heat ruin it—for your health or your smile.

WhyBearaChippedTooth

Having a chipped tooth certainly can make life more difficult. It not only keeps you from wanting to smile, but it may also make it harder to eat your favorite foods. And that can be a major problem — especially if you need to eat up to 80 pounds of bamboo every day to stay healthy.

Just ask Bai Yun, the female giant panda at the San Diego Zoo. The 23-year-old animal recently chipped one of her lower canines, and her keepers were concerned that it might impair her ability to get good nutrition (pandas spend as many as 12 hours a day munching on the woody plants). So they decided it was time for a little dental work!

What followed was not unlike a regular visit to the dental office… except that, instead of sitting in a chair, the 227-pound panda reclined on a large table. After being anesthetized, the patient’s teeth were examined, and x-rays were taken. A composite resin was applied to the damaged tooth, and it was cured with a special light. After the repair work was done, her teeth were given a professional cleaning. When the anesthesia wore off, Bai Yun was released in good health — and ready to eat more bamboo.

Tooth bonding with composite resin is the restoration of choice in many situations. This method can be used to repair small chips or cracks in the teeth, and to clear up some spacing irregularities. The resin itself is a mixture of tough, translucent plastic and glass components that can be made in a number of different shades, which look remarkably like the tooth’s natural enamel coating. And the bonding material links up so well with the tooth structure that this treatment can be expected to last for years.

Another benefit of bonding is that it can be done right in the office — there’s no lab work involved (as there could be for veneers or crowns, for example). That makes it a relatively simple and economical treatment that can typically be completed in a single visit. It’s ideal for fixing minor flaws that don’t involve a great deal of tooth structure. It’s also a cost-effective solution for teenagers who need cosmetic dental work, but must wait until they have stopped growing to get more permanent restorations.

While it isn’t usually as long-lasting as restorations like crowns and veneers, cosmetic bonding is a minimally invasive, reversible treatment that can keep your smile healthy and bright for years to come. And that’s important — whether or not you spend most of your day eating bamboo and posing for snapshots at the zoo.

If you have questions about whether cosmetic bonding could help your smile look its best, please contact us or schedule an appointment for a consultation. You can learn more by reading the Dear Doctor magazine articles “Repairing Chipped Teeth” and “Artistic Repair Of Front Teeth With Composite Resin.”

CrazyLittleThingCalledHyperdontia

The movie Bohemian Rhapsody celebrates the iconic rock band Queen and its legendary lead vocalist, Freddie Mercury. But when we see pictures of the flamboyant singer, many fans both old and new may wonder—what made Freddie’s toothy smile look the way it did? Here’s the answer: The singer was born with four extra teeth at the back of his mouth, which caused his front teeth to be pushed forward, giving him a noticeable overbite.

The presence of extra teeth—more than 20 primary (baby) teeth or 32 adult teeth—is a relatively rare condition called hyperdontia. Sometimes this condition causes no trouble, and an extra tooth (or two) isn’t even recognized until the person has an oral examination. In other situations, hyperdontia can create problems in the mouth such as crowding, malocclusion (bad bite) and periodontal disease. That’s when treatment may be recommended.

Exactly what kind of treatment is needed? There’s a different answer for each individual, but in many cases the problem can be successfully resolved with tooth extraction (removal) and orthodontic treatment (such as braces).┬áSome people may be concerned about having teeth removed, whether it’s for this problem or another issue. But in skilled hands, this procedure is routine and relatively painless.

Teeth aren’t set rigidly in the jawbone like posts in cement—they are actually held in place dynamically by a fibrous membrane called the periodontal ligament. With careful manipulation of the tooth, these fibers can be dislodged and the tooth can be easily extracted. Of course, you won’t feel this happening because extraction is done under anesthesia (often via a numbing shot). In addition, you may be given a sedative or anti-anxiety medication to help you relax during the procedure.

After extraction, some bone grafting material may be placed in the tooth socket and gauze may be applied to control bleeding; sutures (stitches) are sometimes used as well. You’ll receive instructions on medication and post-extraction care before you go home. While you will probably feel discomfort in the area right after the procedure, in a week or so the healing process will be well underway.

Sometimes, dental problems like hyperdontia need immediate treatment because they can negatively affect your overall health; at other times, the issue may be mainly cosmetic. Freddie Mercury declined treatment because he was afraid dental work might interfere with his vocal range. But the decision to change the way your smile looks is up to you; after an examination, we can help you determine what treatment options are appropriate for your own situation.

If you have questions about tooth extraction or orthodontics, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “Simple Tooth Extraction” and “The Magic of Orthodontics.”

TreatmentOptionstoKeepStressFromCausingDentalProblems

Chronic stress can cause any number of physical problems like back pain, insomnia or stomach ulcers. In the mouth, it can also be the cause of teeth grinding or clenching habits that may lead to pain and tooth damage.

Besides toothaches and jaw pain, stress-related teeth grinding may also be causing your teeth to wear at a faster than normal rate. While the teeth can withstand normal forces generated from biting and chewing, a grinding habit could be subjecting the teeth to forces beyond their normal range. Over time, this could produce excessive tooth wear and contribute to future tooth loss.

Here, then, are some of the treatment options we may use to stop the effects of stress-related dental habits and provide you with relief from pain and dysfunction.

Drug Therapy. Chronic teeth grinding can cause pain and muscle spasms. We can reduce pain with a mild anti-inflammatory pain reliever (like ibuprofen), and spasms with a prescribed muscle relaxant drug. If you have sleep issues, you might also benefit from occasional sleep aid medication.

A Night or Occlusal Guard. Also known as a bite guard, this appliance made of wear-resistant acrylic plastic is custom-fitted to the contours of your bite. The guard is worn over your upper teeth while you sleep or when the habit manifests; the lower teeth then glide over the hard, smooth surface of the guard without biting down. This helps rest the jaw muscles and reduce pain.

Orthodontic Treatment. Your clenching habit may be triggered or intensified because of a problem with your bite, known as a malocclusion. We can correct or limit this problem by either moving the teeth into a more proper position or, if the malocclusion is mild, even out the bite by reshaping the teeth in a procedure known as occlusal (bite) equilibration.

Psychological Treatment. While the preceding treatments can help alleviate or correct dental or oral structural problems, they may not address the underlying cause for a grinding habit — your psychological response to stress. If you’re not coping with stress in a healthy way, you may benefit from treatments in behavioral medicine, which include biofeedback or psychological counseling.
