Although dental care has made incredible advances over the last century, the underlying approach to treating tooth decay has changed little. Today’s dentists treat a decayed tooth in much the same way as their counterparts from the early 20th Century: remove all decayed structure, prepare the tooth and fill the cavity.

Dentists still use that approach not only because of its effectiveness, but also because no other alternative has emerged to match it. But that may change in the not-too-distant future according to recent research.

A research team at Kings College, London has found that a drug called Tideglusib, used for treating Alzheimer’s disease, appears to also stimulate teeth to regrow some of its structure. The drug seemed to cause stem cells to produce dentin, one of the tooth’s main structural layers.

During experimentation, the researchers drilled holes in mouse teeth. They then placed within the holes tiny sponges soaked with Tideglusib. They found that within a matter of weeks the holes had filled with dentin produced by the teeth themselves.

Dentin regeneration isn’t a new phenomenon, but other occurrences of regrowth have only produced it in tiny amounts. The Kings College research, though, gives rise to the hope that stem cell stimulation could produce dentin on a much larger scale. If that proves out, our teeth may be able to create restorations by “filling themselves” that are much more durable and with possibly fewer complications.

As with any medical breakthrough, the practical application for this new discovery may be several years away. But because the medication responsible for dentin regeneration in these experiments with mouse teeth is already available and in use, the process toward an application with dental patients could be relatively short.

If so, a new biological approach to treating tooth decay may one day replace the time-tested filling method we currently use. One day, you won’t need a filling from a dentist—your teeth may do it for you.

There are a few mouth conditions so rare most of us have never heard of them. Geographic tongue would fall into this category, affecting only one to three percent of the population. Even so, these irregular reddish patches resembling land masses on a map (hence the name) might be alarming at first glance—but they pose no danger and usually cause very little discomfort.

Geographic tongue is also known as benign migratory glossitis. As its clinical name implies, the unusual red patchy areas (often surrounded by a grayish white border) aren't cancerous nor contagious. The patches also appear to change shape and move around ("migrate") the tongue.

The reddish appearance comes from the temporary disappearance of tiny bumps on the tongue surface called papillae, which can leave the tongue smooth to the touch in affected areas. The lost papillae may reappear again a few hours or days later, and may occasionally disappear again. While it's not painful, you can experience a stinging or burning sensation emitting from these patchy areas.

We're not sure how and why geographic tongue erupts, but it's believed high emotional or psychological stress, hormonal imbalance or certain vitamin deficiencies might be factors in its cause. There may also be a link between it and psoriasis, a condition that can cause dry, itchy patches on the skin.

If you're one of the rare individuals who has episodes of geographic tongue, the good news is it's harmless, only mildly uncomfortable and usually temporary. The bad news, though, is that there's no known cure for the condition—but it can be managed to ease discomfort during outbreaks.

It's been found that highly acidic and spicy foods, as well as astringents like alcohol or some mouthrinses, can increase the level of discomfort. By avoiding these or similar foods or substances, you can reduce the irritation. Your dentist may also be able to help by prescribing anesthetic mouthrinses, antihistamines or steroid ointments.

For the most part, you'll simply have to wait it out. Other than the mild, physical discomfort, the worst part is often simply the appearance of the tongue. But by watching your diet and other habits, and with a little help from us, you can cope with these irritations when it occurs.

What does November make you think of? Pumpkins? Turkeys? Dry leaves and frosty mornings? How about cigarette butts?

If you’re wondering about the last item, remember that November 15 is the date of the Great American Smokeout—a day set aside for those who want to take the first steps toward quitting the tobacco habit. While the percentage of smokers in the U.S. has dropped to less than 16% in recent years, according to the American Cancer Society there are still some 38 million Americans who smoke cigarettes. Smoking causes over 480,000 deaths every year, and is the leading preventable cause of death in the U.S.

Even if it doesn’t kill you, the effects of tobacco use can be devastating to your entire body—including your mouth. Whether you smoke cigarettes or use chewing tobacco, your risk of oral cancer is greatly increased, as is your chance of developing periodontal (gum) disease. What’s more, smoking can mask the symptoms of gum disease, so your condition is actually worse than it appears. Severe gum disease is one reason why smokers tend to lose more teeth than non-smokers.

In addition, because smoking interferes with the natural healing process, smokers have a much greater chance of dental implant failure. Tobacco use also can lead to increased amounts of plaque, which results in tooth decay and other oral health problems. It also stains your teeth, reduces your senses of smell and taste, and gives you bad breath.

Ready to quit yet? If so, there are lots of resources to help you on the road to a healthier life. The American Cancer Society, sponsor of the Smokeout, can help you make a plan to quit tobacco—and stay off it. It’s not easy, but over a million Americans do it every year. See their website for more information, plans and tips on quitting. Your health care professionals are also a great source of information and help when it’s time to get off the tobacco habit. Feel free to ask us any questions you may have.

And here’s the good news: The moment you quit, your body begins to recover from the effects of tobacco use. In just one year, you’ll have cut your risk of heart attack and stroke in half. After 5 to 15 years, your risk of stroke, coronary heart disease, and several other conditions is the same as someone who has never smoked.

Not coincidentally, GERD Awareness Week overlaps with the Thanksgiving holiday. Many people get acid indigestion from time to time, especially during this month of major feasting, but if you suffer from more than occasional acid reflux, you may be among the 20 percent of U.S. adults with gastroesophageal reflux disease, or GERD. For many individuals, painful heartburn often accompanies acid reflux; however, for others there are few or no symptoms. In the latter situation, dentists may be the first to suspect GERD based on what we see during a regular dental exam.

With GERD, acid washes up from the stomach into the esophagus or throat, and even into the mouth. If the condition is not treated, the repeated contact with acid can lead to ulcers and cause pre-cancerous cell changes along the esophagus lining. In addition, the acids can eat away at tooth enamel and harm the soft tissues of the mouth, which may result in severely eroded teeth and chronic gum disease. Unfortunately for those who have relatively minor symptoms, GERD may go undetected until serious damage has been done. For this reason, diagnosis and treatment of GERD is very important.

You can play a big role in managing your GERD symptoms. Besides taking any over-the-counter or prescription medication your doctor recommends, you can help control acid reflux by eating smaller meals, avoiding foods and beverages that trigger heartburn, refraining from eating within three hours of bedtime, and resisting the urge to recline right after eating. Also, quitting smoking and taking off extra weight can help greatly.

Further, it is important to take steps to protect your teeth if you suffer from GERD. Here are some tips:

• Neutralize acid by chewing on an antacid tablet or rinsing your mouth with half a teaspoon of baking soda mixed into a cup of water.
• Don't brush your teeth immediately after an episode of acid reflux, as this could damage the weakened tooth enamel. Instead, rinse your mouth with water to dilute the acid and wait an hour before you brush to allow your saliva to rebuild the minerals on the surface of your teeth.
• Schedule regular dental visits to monitor the health of your teeth and gums. Depending on your specific situation, we may recommend a particular treatment to help strengthen your teeth.

Our goal is to help you preserve your teeth for life, so be sure to tell us if you have been diagnosed with GERD or any other medical condition. If you have questions, contact us or schedule an appointment for a consultation.

While your chances of losing teeth increase as you age, it's not a given. With proper hygiene and care your teeth could last a lifetime.

But brushing and flossing can become more difficult in later years. Arthritis or strength issues in the fingers and hands make holding a toothbrush an arduous chore and flossing next to impossible.

But you can accommodate these physical changes. Many seniors find using a powered toothbrush much easier to handle and effective for removing disease-causing plaque. A tennis ball or bike handle grip attached to a manual toothbrush can also make it easier to handle. As to flossing, older people may find it easier to use floss threaders or a water irrigator, which removes plaque from between teeth with a pressurized water spray.

You may also find changes in the mouth that increase your risk for dental disease. One such issue is xerostomia, dry mouth. As you age you don't produce as much saliva, which neutralizes acid and restores minerals to enamel, as when you were younger. Dry mouth can also be a side effect of certain medications. Older people are also more likely to suffer from gastric reflux, which can introduce stomach acid into the mouth.

With these dry, acidic conditions, you're more susceptible to both tooth decay and periodontal (gum) disease. You can help offset it by increasing water consumption, taking a saliva stimulator, changing to alternative medications if available, and relieving gastric reflux.

Another area of concern in aging is the higher risk for inflammatory diseases like diabetes or cardiovascular diseases (CVD), which could also increase your risk of periodontal (gum) disease. Seeking treatment for gum disease and other similar systemic diseases may help ease the effects of each one.

Taking care of your mouth can be challenging as you grow older. But tooth loss and other unpleasant results aren't inevitable. Invest in your teeth and gums today and you're more likely to have a healthy life and smile all through your golden years.
