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.
Boston Bruins defenseman Zdeno Chara had a rough Stanley Cup final against the St. Louis Blues this past June. Not only did the Bruins ultimately lose the championship, but Chara took a deflected puck shot to the face in Game Four that broke his jaw.
With the NHL season now over, the 42-year-old Bruins captain continues to mend from his injury that required extensive treatment. His experience highlights how jaw fractures and related dental damage are an unfortunate hazard in hockey—not only for pros like Chara, but also for an estimated half million U.S. amateurs, many in youth leagues.
Ice hockey isn't the only sport with this injury potential: Basketball, football (now gearing up with summer training) and even baseball players are also at risk. That's why appropriate protective gear like helmets and face shields are key to preventing injury.
For any contact sport, that protection should also include a mouthguard to absorb hard contact forces that could damage the mouth, teeth and gums. The best guards (and the most comfortable fit) are custom-made by a dentist based on impressions made of the individual's mouth.
But even with adequate protection, an injury can still happen. Here's what you should do if your child has an injury to their jaw, mouth or teeth.
Recognize signs of a broken jaw. A broken jaw can result in severe pain, swelling, difficulty speaking, numbness in the chin or lower lip or the teeth not seeming to fit together properly. You may also notice bleeding in the mouth, as well as bruising under the tongue or a cut in the ear canal resulting from jawbone movement during the fracture. Get immediate medical attention if you notice any of these signs.
Take quick action for a knocked-out tooth. A tooth knocked completely out of its socket is a severe dental injury. But you may be able to ultimately save the tooth by promptly taking the following steps: (1) find the tooth and pick it up without touching the root end, (2) rinse it off, (3) place it back in its socket with firm pressure, and (4) see a dentist as soon as possible.
Seek dental care. Besides the injuries already mentioned, you should also see a dentist for any moderate to severe trauma to the mouth, teeth and gums. Leading the list: any injury that results in tooth chipping, looseness or movement out of alignment.
Even a top athlete like Zdeno Chara isn't immune to injury. Take steps then to protect your amateur athlete from a dental or facial injury.

For years people tuned in to enjoy one of David Letterman's "Top 10 lists," a frequent gag performed on his show Late Night. Each countdown list poked fun at off-the-wall topics like "Top 10 New York City Science Projects" or "Top 10 Questions People Ask when Shopping for an Umbrella."
Recently, the American Dental Association presented their own kind of list—"America's Top 3 Oral Health Problems"—based on surveys of around 15,000 people across the U.S. But unlike the popular Late Night lists, this one is no laughing matter.
Coming in at #3, 29% of the respondents indicated they had experienced tooth pain at some time in their life. Tooth pain is the body's way of alerting to trouble in the mouth, anything from a decayed tooth to a gum abscess. The best thing to do if you have any persistent oral pain is to see your dentist as soon as possible for a thorough examination. And you should do this even if the pain goes away.
The second most prominent oral problem among people is difficulty biting or chewing, about 31% of those in the surveys. As with tooth pain, the reasons can vary greatly, including cracked, loose or deeply decayed teeth, dentures or jaw joint disorders (TMD). Because dental disease is usually the ultimate culprit, the best way to avoid this is to practice daily brushing and flossing and regular dental visits. And, as with tooth pain, you should see your dentist if you're having symptoms.
At 33% of respondents, the number one oral problem in America is chronic dry mouth. It's a constant inadequate flow of saliva often caused by medications or certain systemic conditions. Because saliva helps protect the mouth against infection, a restricted flow increases your risk of disease. If you notice your mouth is dry all the time, you should talk to your dentist about ways to boost your saliva. If you're taking medications, ask your doctor if they could be causing your symptoms and if you could change to something else.
While any of these Top 3 oral problems can be a stepping stone to more serious dental problems, it doesn't necessarily have to lead to that. You can improve your dental health through daily oral hygiene and regular dental treatment. And it might help you stay off this unpleasant list.
