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.
Tooth decay is more prevalent than diseases like cancer, heart disease or influenza. It doesn't have to be—brushing with fluoride toothpaste, flossing, less dietary sugar and regular dental cleanings can lower the risk of this harmful disease.
Hygiene, diet and dental care work because they interrupt the disease process at various points. Daily hygiene and regular dental cleanings remove dental plaque where oral bacteria flourish. Reducing sugar eliminates one of bacteria's feeding sources. With less bacteria, there's less oral acid to erode enamel.
But as good as these methods work, we can now take the fight against tooth decay a step further. We can formulate a prevention strategy tailored to an individual patient that addresses risk factors for decay unique to them.
Poor saliva flow. One of the more important functions of this bodily fluid is to neutralize mouth acid produced by bacteria and released from food during eating. Saliva helps restore the mouth's ideal pH balance needed for optimum oral health. But if you have poor saliva flow, often because of medications, your mouth could be more acidic and thus more prone to decay.
Biofilm imbalance. The inside of your mouth is coated with an ultrathin biofilm made up of proteins, biochemicals and microorganisms. Normally, both beneficial and harmful bacteria reside together with the “good” bacteria having the edge. If the mouth becomes more acidic long-term, however, even the beneficial bacteria adapt and become more like their harmful counterparts.
Genetic factors. Researchers estimate that 40 to 50 hereditary genes can impact cavity development. Some of these genes could impact tooth formation or saliva gland anatomy, while others drive behaviors like a higher craving for sugar. A family history of tooth decay, especially when regular hygiene habits or diet don't seem to be a factor, could be an indicator that genes are influencing a person's dental health.
To determine if these or other factors could be driving a patient's higher risk for tooth decay, many dentists are now gathering more information about medications, family history or lifestyle habits. Using that information, they can introduce other measures for each patient that will lower their risk for tooth decay even more.

You've heard it. Your parents heard it—maybe even your grandparents too. Dentists have been alerting people for more than half a century that high sugar consumption contributes to tooth decay.
That message hasn't changed because the facts behind it are the same in the 2020s as they were in the 1950s: The bacteria that cause tooth decay feast on sugar and other leftover carbohydrates in the mouth. This causes them to multiply and increase their production of acid, which softens and erodes tooth enamel.
What has changed though, especially over the last couple of decades, is a growing understanding of how sugar consumption may affect the rest of the body. Just like the evidence of sugar's relationship to tooth decay, current scientific studies are now showing there are strong links between sugar and diseases like diabetes, heart disease and liver disease.
What's startling about what researchers are finding is that cases of these diseases are growing, Especially in younger people. This is a parallel trend to our skyrocketing increases in per capita sugar consumption: the average American now eats the equivalent of 19.5 teaspoons of added sugar every day. Health experts generally agree we should consume no more than 6 teaspoons a day, and children 4.
This is vastly more than we consumed a generation ago. One reason is because processed food manufacturers have increased sugar in their products, hiding under technical, unfamiliar names in ingredient lists. But it's still sugar, and an estimated 74% of processed foods contain some form of it.
But the real surge in sugar has come from our increasing consumption of sodas, as well as energy and sports beverages. These beverages are high in sugar—you can meet your daily allowance with just one 12-oz can of soda. These beverages are now the leading source of sugar in our diets, and, according to experts, a highly dangerous way to consume it.
In effect, dentists of old were on to something: too much sugar is bad for your teeth. It now turns out that it may be bad for your overall health too. Strictly limiting it in your family's diet could help lower your risk of tooth decay and dangerous diseases like diabetes.
Tooth decay is one of the world's most prevalent diseases — and one of the most preventable. We've known the primary prevention recipe for decades: brushing and flossing daily, and dental cleanings and checkups at least twice a year.
But consistent oral hygiene isn't enough — you should also pay attention to your overall health, diet and lifestyle habits. Each of these areas in their own way can contribute to abnormally high mouth acid, which can soften enamel and open the door to tooth decay.
Lower saliva production is one such problem that can arise due to issues with your health. Among its many properties, saliva neutralizes acid and helps maintain the mouth's optimum neutral pH level. But some health conditions or medications can reduce saliva flow: less saliva means less neutralization and chronic acidity.
You can also inhibit saliva flow with one particular lifestyle habit — smoking. Tobacco smoke can damage salivary glands. Nicotine, tobacco's active ingredient, constricts blood vessels, leading to fewer antibodies delivered by the blood stream to mouth tissues to fight disease.
A diet heavy on acidic foods and beverages can also increase mouth acidity. It's not only what you're eating or drinking — it's also how often. If you're constantly snacking or sipping on something acidic, saliva doesn't have a chance to complete the neutralizing process.
In addition to your daily oral hygiene practice, you should also make changes in these other areas to further lower your risk of tooth decay. If you're taking medications that cause dry mouth, see if your doctor can prescribe a different one or try using products that stimulate saliva. Quit smoking, of course, as much for your mouth as for the rest of your health.
On the dietary front, reduce your intake of acidic foods and beverages, especially sodas, energy or sports drinks. If you've counted on the latter for hydration, switch to water instead. And limit acidic foods to mealtime rather than throughout the day.
It's all about maintaining a healthy pH level in your mouth. Doing so along with good oral hygiene will help you better avoid destructive tooth decay.

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.
