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.
If your dentist found tooth decay on your last visit, you might have been surprised. But tooth decay doesn't occur suddenly—it's a process that takes time to unfold.
It begins with bacteria—too many, that is. Bacteria naturally live in the mouth, but when their populations grow (often because of an abundance of leftover sugar to feed on) they produce high amounts of acid, a byproduct of their digestion. Too much acid contact over time softens and eventually erodes tooth enamel, making decay easier to advance into the tooth.
So, one important strategy for preventing tooth decay is to keep your mouth's bacterial population under control. To do that, here are 4 common-sense tactics you should perform between dental visits.
Practice daily hygiene. Bacteria thrive in dental plaque, a thin film of food particles that builds up on teeth. By both brushing and flossing you can reduce plaque buildup and in turn reduce disease-causing bacteria. In addition, brushing with a fluoride toothpaste can also help strengthen tooth enamel against acid attacks.
Cut back on sugar. Reducing how much sugar you eat—and how often –deprives bacteria of a prime food source. Constant snacking throughout the day on sweets worsens the problem because it prevents saliva, the body's natural acid neutralizer, from reducing high acid levels produced while eating. Constant snacking doesn't allow saliva to complete this process, which normally takes about thirty minutes to an hour. To avoid this scenario, limit any sweets you eat to mealtimes only.
Wait to brush after eating. Although this sounds counterintuitive, your tooth enamel is in a softened state until saliva completes the acid neutralizing process previously described. If you brush immediately after eating you could brush away tiny particles of softened enamel. Instead, rinse your mouth out with water and wait an hour for saliva to do its work before brushing.
Boost your saliva. Inadequate saliva flow could inhibit the fluid's ability to adequately neutralize acid or provide other restorative benefits to tooth enamel. You can improve flow with supplements or medications, or by drinking more water during the day. Products with xylitol, a natural sugar alternative, could give you a double benefit: chewing gums and mints containing it could stimulate more saliva flow and the xylitol itself can inhibit bacterial growth.
Dental caries (tooth decay) is a leading cause of tooth loss. But with prompt diagnosis and care we can often stop it before it causes too much damage.
The traditional treatment approach is simple: remove all diseased tooth structure and then restore the tooth with a filling. But this otherwise effective treatment has one drawback: you may lose significant healthy structure to accommodate a suitable filling or to make vulnerable areas easier to clean from bacterial plaque.
That's why a new treatment approach called minimally invasive dentistry (MID) is becoming more common. The goal of MID is to remove as little of a tooth's natural enamel and dentin as possible. This leaves the treated tooth stronger and healthier, and could reduce long-term dental costs too.
Here's how MID could change your future dental care.
Better risk assessment. MID includes a treatment protocol called caries management by risk assessment (CAMBRA). With CAMBRA, we evaluate your individual tooth decay risk, including oral bacteria levels, the quality of saliva flow to neutralize mouth acid, and sugar consumption. We then use our findings to customize a treatment plan that targets your areas of highest risk.
New detection methods. The real key to fighting tooth decay is to find it before it can destroy tooth structure with the help of new diagnostic technology. Besides advances in x-ray imaging that provide better views with less radiation exposure, we're also using powerful dental microscopes, lasers and infrared photography to show us more about your teeth than we can see with the naked eye.
"Less is More" treatments. In contrast to the dental drill, many dentists are now using air abrasion rather than a dental drill to remove decayed tooth material. Air abrasion emits tiny material particles within a pressurized air stream that leaves more healthy tooth structure intact than with drilling. We're also using new filling materials like composite resin that not only resemble natural tooth color, but require less structural removal than other types of fillings.
Using MID, we can treat tooth decay while preserving more of your natural teeth. This promises better long-term outcomes for future dental health.

The basics for treating tooth decay have changed little since the father of modern dentistry Dr. G.V. Black developed them in the early 20th Century. Even though technical advances have streamlined treatment, our objectives are the same: remove any decayed material, prepare the cavity and then fill it.
This approach has endured because it works—dentists practicing it have preserved billions of teeth. But it has had one principle drawback: we often lose healthy tooth structure while removing decay. Although we preserve the tooth, its overall structure may be weaker.
But thanks to recent diagnostic and treatment advances we’re now preserving more of the tooth structure during treatment than ever before. On the diagnostic front enhanced x-ray technology and new magnification techniques are helping us find decay earlier when there’s less damaged material to remove and less risk to healthy structure.
Treating cavities has likewise improved with the increased use of air abrasion, an alternative to drilling. Emitting a concentrated stream of fine abrasive particles, air abrasion is mostly limited to treating small cavities. Even so, dentists using it say they’re removing less healthy tooth structure than with drilling.
While these current advances have already had a noticeable impact on decay treatment, there’s more to come. One in particular could dwarf every other advance with its impact: a tooth repairing itself through dentin regeneration.
This futuristic idea stems from a discovery by researchers at King’s College, London experimenting with Tideglusib, a medication for treating Alzheimer’s disease. The researchers placed tiny sponges soaked with the drug into holes drilled into mouse teeth. After a few weeks the holes had filled with dentin, produced by the teeth themselves.
Dentin regeneration isn’t new, but methods to date haven’t been able to produce enough dentin to repair a typical cavity. Tideglusib has proven more promising, and it’s already being used in clinical trials. If its development continues to progress, patients’ teeth may one day repair their own cavities without a filling.
Dr. Black’s enduring concepts continue to define tooth decay treatment. But developments now and on the horizon are transforming how we treat this disease in ways the father of modern dentistry couldn’t imagine.
You've no doubt heard about certain foods and beverages that increase your risk for dental disease. These foods, often high in added sugar or acid, can lead to tooth decay or periodontal (gum) disease.
But have you heard about foods with the opposite effect — actually protecting your teeth against disease? Many of these dental-friendly foods are plant-based and fibrous: they stimulate saliva production, one of the mouth's best disease-fighting weapons.
But there are also some foods you might not expect to make the good list for dental health. Here are 3 surprising foods that could help you fight dental disease.
Cheese. We've long recognized milk as important to dental health — but cultured dairy products like cheese are also good for teeth. Cheese stimulates saliva, which neutralizes acid and replenishes the enamel's mineral content. Cheese also contains decay-stopping minerals like calcium, phosphorous and casein. And although milk cheese contains the sugar lactose, this particular type triggers less acid production than other sugars.
Black & green teas. You may have heard about the staining effect of tea, and avoided it as a result. But both forms of tea are also rich in antioxidants, substances that protect us against disease, including in the mouth. Black tea also contains fluoride, which strengthens enamel against cavities. If you drink tea, of course, you should exercise diligent hygiene to reduce any staining effect.
Chocolate. Yes, you read that right, chocolate: unrefined cocoa to be exact, which contains a number of compounds that resist decay. Ah, but there's a catch — chocolate in the form of your favorite candy bar usually contains high amounts of sugar. Sweetened chocolate, then, is a mixed bag of decay-resistive compounds and decay-promoting sugar. To get the benefit you'll have to partake of this favorite food of the Aztecs in a more raw, less sweetened form.
Of course, there's no single wonder food that prevents tooth decay. Your best approach is a diet rich in fresh fruits and vegetables, dairy and quality protein while limiting sugar-added and acidic foods.Â And don't forget daily brushing and flossing, coupled with regular dental visits for cleanings and checkups. Having a comprehensive dental care plan will help ensure your teeth remain healthy and disease-free.
