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.

As the host of America's Funniest Home Videos on ABC TV, Alfonso Ribeiro has witnessed plenty of unintentional physical comedy…or, as he puts it in an interview with Dear Doctor–Dentistry & Oral Health magazine, "When people do stuff and you're like, 'Dude, you just hurt yourself for no reason!'" So when he had his own dental dilemma, Alfonso was determined not to let it turn onto an "epic fail."

The television personality was in his thirties when a painful tooth infection flared up. Instead of ignoring the problem, he took care of it by visiting his dentist, who recommended a root canal procedure. "It's not like you wake up and go, 'Yay, I'm going to have my root canal today!'" he joked. "But once it's done, you couldn't be happier because the pain is gone and you're just smiling because you're no longer in pain!"

Alfonso's experience echoes that of many other people. The root canal procedure is designed to save an infected tooth that otherwise would probably be lost. The infection may start when harmful bacteria from the mouth create a small hole (called a cavity) in the tooth's surface. If left untreated, the decay bacteria continue to eat away at the tooth's structure. Eventually, they can reach the soft pulp tissue, which extends through branching spaces deep inside the tooth called root canals.

Once infection gets a foothold there, it's time for root canal treatment! In this procedure, the area is first numbed; next, a small hole is made in the tooth to give access to the pulp, which contains nerves and blood vessels. The diseased tissue is then carefully removed with tiny instruments, and the canals are disinfected to prevent bacteria from spreading. Finally, the tooth is sealed up to prevent re-infection. Following treatment, a crown (cap) is usually required to restore the tooth's full function and appearance.

Root canal treatment sometimes gets a bad rap from people who are unfamiliar with it, or have come across misinformation on the internet. The truth is, a root canal doesn't cause pain: It relieves pain! The alternatives—having the tooth pulled or leaving the infection untreated—are often much worse.

Having a tooth extracted and replaced can be costly and time consuming…yet a missing tooth that isn't replaced can cause problems for your oral health, nutrition and self-esteem. And an untreated infection doesn't just go away on its own—it continues to smolder in your body, potentially causing serious problems. So if you need a root canal, don't delay!

Your child's permanent teeth come in gradually, starting just as they begin losing their primary ("baby") teeth and not ending until late adolescence or early adulthood. That's when the third molars or "wisdom teeth" close out the process.

Because of their late arrival, wisdom teeth have a high potential for dental problems. With a greater chance of crowding or obstruction by other teeth, wisdom teeth often get stuck fully or partially below the gums and bone (impaction) or erupt out of position. In one study, 7 in 10 people between the ages of 20 and 30 will have at least one impacted wisdom tooth at some time in their lives.

It's not surprising then that wisdom teeth are among the most extracted teeth, to the tune of about 10 million per year. Besides those already diseased or causing bite problems, many are removed preemptively in an attempt to avoid future problems.

But wisdom teeth usually require surgical extraction by an oral surgeon, which is much more involved than a simple extraction by a general dentist. Given the potential consequences of surgical extraction, is it really necessary to remove a wisdom tooth not creating immediate problems?

That's not an easy question to answer because it's often difficult to predict a wisdom tooth's developmental track. Early on it can be disease-free and not causing any problems to other teeth. But as some researchers have found, one in three wisdom teeth at this stage will later develop disease or create other issues.

For many dentists, the best approach is to consider extraction on a case by case basis. Those displaying definite signs of problems are prime for removal. But where there are no signs of disease or other issues, the more prudent action may be to keep a watchful eye on their development and decide on extraction at some later date.

More than likely, your dentist will continue to have an ongoing discussion with you about the state of your child's wisdom teeth. While extraction is always an option, wisdom teeth that aren't yet a problem to dental health may be best left alone.

With summer vacation season in full swing, you and your family might be planning a trip away from home, maybe even far from home. If you’re vacationing out of the country, you’ll want to be as prepared as possible—including protecting your dental health.

Dental problems are difficult enough in the familiar surroundings of home, but even more so in a foreign locale. However, with a little preparation and planning, you can keep your exotic dream vacation from becoming a dental nightmare.

Here’s what you can do to avoid or minimize an unpleasant situation with your teeth and gums while on vacation abroad.

Take care of any dental problems before you leave. If you know or suspect you already have a problem with your teeth or gums, it’s better to have it corrected if at all possible before your trip. So, make an appointment to see your dentist if you notice things like a toothache or tooth sensitivity, unusual spotting on your teeth, or swollen or bleeding gums.

You should also have sinus problems like pain or congestion checked too, since these may actually involve your teeth and gums. If at all possible, undergo recommended procedures like gum disease treatment or root canals pre-trip—just be sure you allow adequate time for recuperation before your departure date.

Know who to contact in a dental emergency. Even with the best of planning, you should also prepare for the possibility of a dental injury or emergency while you’re on your vacation. So be sure you pack along with your other travel documents the names and contact information of individuals or organizations near your vacation destination that might be of assistance in a dental emergency. These might include hotel concierges, military personnel or other English speakers living in the area, or the nearest embassy or consulate.

In addition, the International Association for Medical Assistance to Travelers and the Organization for Safety, Asepsis and Prevention are online resources that can help you with your trip planning and give you medical and dental information specific to your destination.

A vacation trip to a foreign land can be a unique and fulfilling experience. Just be sure a dental problem or emergency doesn’t spoil the moment—be prepared.
