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.
True or false: there’s no cause for concern about tooth decay until your child’s permanent teeth erupt.
False—decayed primary teeth can lead to potentially serious consequences later in life.
Although “baby” teeth last only a few years, they’re essential to future dental health because they act as placeholders and guides for the incoming permanent teeth. If they’re lost prematurely due to decay, other teeth may drift into the empty space intended for the emerging permanent tooth. Because of this, inadequate space will crowd the out of proper alignment.
And because they have thinner enamel than permanent teeth, primary teeth are more susceptible to decay. Once decay sets in, it can spread rapidly in a matter of months.
Fortunately, we may be able to prevent this from happening to your child’s primary teeth with a few simple guidelines. It all begins with understanding the underlying causes of tooth decay.
Tooth decay begins with bacteria: As a result of their digestion, these microorganisms secrete acid that at high levels can erode tooth enamel. The higher the population of bacteria in the mouth, the higher the acidity and potential threat to the teeth.
The first objective then in preventing decay is to remove dental plaque, the thin film of bacteria and food particles on tooth surfaces, through daily brushing and flossing. And because bacteria feed on sugar as a primary food source, you should reduce your child’s sugar consumption by restricting it to only meal times and not sending your child to bed with a bottle filled with a sugary liquid (including formula or breast milk).
To help boost your child’s protection, we can also apply sealants and fluoride to teeth to help protect and strengthen their enamel from acid attack. Because we’ll also monitor for signs of decay, it’s important to begin regular dental visits beginning around age one. If we do detect decay, we can then treat it and make every effort to preserve your child’s primary teeth until they’ve completed their normal life cycle.
By taking these steps, we can help make sure your child’s early teeth go the distance. Their current and future dental health will certainly benefit.

Each year thousands of people develop sinus infections from various causes. But there's one cause for sinusitis that might surprise you—tooth decay.
Tooth decay begins when the acid produced by oral bacteria erodes a tooth's enamel protection to create a small hole or cavity. Left untreated, the infection can move into the inner pulp of the tooth and tiny passageways leading to the roots called root canals. The decay can then infect and break down the structure of the supporting jawbone.
This could affect the sinus cavities, hollow air-filled spaces in the upper portion of the face. The maxillary sinus in particular sits behind the cheek bones just above the upper jaw. Tooth roots, particularly in back teeth, can extend quite near or even poke through the floor of the maxillary sinus.
If decay affects these roots, the bone beneath this floor may begin to break down and allow the bacterial infection to enter the sinus. We call this particular kind of sinus infection maxillary sinusitis of endodontic origin (MSEO), "endodontic" referring to the interior structure of teeth.
While advanced decay can show symptoms like pain or sensitivity with certain hot or cold foods, it's also possible to have it and not know it directly. But a recurring sinus infection could be an indirect indication that the root of your suffering is a deeply decayed tooth. Treating the sinus infection with antibiotics won't cure this underlying dental problem. For that you'll need to see a dentist or an endodontist, a specialist for interior tooth issues.
The most common way to treat deep tooth decay is with root canal therapy. In this procedure, the dentist enters the decayed tooth's pulp (nerve chamber) and root canals and removes the diseased tissue. They will then fill the empty pulp and root canals with a special filling and seal the tooth to prevent future infection. The procedure stops the infection and saves the tooth—and if you have MSEO, it eliminates the cause of the sinus infection.
So, if you're suffering from chronic sinus infections, you might talk with your dentist about the possibility of a tooth infection. A thorough examination might reveal a decayed tooth in need of treatment.
All-natural fruit juice with no additives: now what could be wrong with that? Nothing—unless your child is over-indulging. Too much of even natural fruit juice could increase their risk of tooth decay.
To understand why, we first need to look at the real culprit in tooth decay: mouth acid produced by oral bacteria as a byproduct of their digestion of sugar. Acid at high levels softens and erodes tooth enamel, which causes tooth decay. Acid levels can rise as populations of bacteria increase often fueled by sugar, one of bacteria's primary food sources.
And not just the added sugar found in soft drinks, snacks or candies—even fructose, the natural sugar found in fruit, can feed bacteria. To lower the risk of tooth decay, dentists recommend limiting the daily amount of sugar a child consumes, including natural fruit juices without added sugar.
That doesn't mean you should nix natural fruit juices altogether—they remain a good source of vitamins, minerals and other nutrients. But you'll need to keep your child's juice consumption within moderation.
As a guide, the American Academy of Pediatrics (AAP) has issued consumption recommendations for children regarding all-natural fruit juice. The academy recommends the following daily juice amounts by age:
- 7-18: 8 ounces (1 cup) or less;
- 4-6: 6 ounces or less;
- 1-3: 4 ounces or less;
- Under 1: No juice at all.
You can further reduce your child's decay risk by limiting their juice intake to mealtimes, a good practice with any sweetened beverage. Sipping through the day on juice or other sweetened beverages can cause some sugar to stay in the mouth over long periods. This can interfere with the natural ability of saliva to neutralize any acid buildup.
If you're wondering what children could drink instead of juice, low-fat or non-fat milk is an acceptable choice. But the most tooth-friendly liquid to drink is plain water. Drinking nature's hydrator is not only better for their overall health, by reducing the risk of tooth decay, it's also better for their teeth.

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.
