Although we've known for some time how tooth decay forms, it's still prevalent across the population—even more so than cancer or heart disease. Along with gum disease, it's a leading cause of tooth loss.
Fortunately, our knowledge about tooth decay has grown considerably, to the point that we now recognize a number of risk factors that make it more likely a person will develop this disease. By first identifying them in individual patients, we can take steps to address them specifically to reduce the chances of this destructive disease.
Genetics. Researchers have identified around 40 to 50 genes that can influence cavity development. The best way to assess your genetic risk is through family history—if numerous close family members contend with tooth decay, your risk may be high. If so, it's important to be extra vigilant with addressing other areas over which you have more control.
Saliva. Cavities are directly caused by oral acid, a byproduct of bacteria, that can erode tooth enamel over prolonged contact. This is minimized, though, through a normal saliva flow that neutralizes acid and helps remineralize enamel. But poor saliva production can slow acid neutralization. You can improve your saliva flow by drinking more water, changing medications or using saliva-boosting products.
Oral hygiene. You can reduce bacteria (and thus acid) by removing their "room and board"—dental plaque. This accumulating film of food particles harbors the bacteria that feed on it. Daily brushing and flossing, accompanied by regular dental cleanings, effectively removes dental plaque, which in turn lowers the levels of oral bacteria and acid.
Dental-friendly diet. Even if you diligently address the previous risk factors, your diet may fight against your efforts. Diets high in processed and refined foods, especially sugar, provide abundant food sources for bacteria. On the other hand, a diet primarily of whole foods rich in vitamins (especially D) and minerals like calcium and phosphorous strengthen teeth against decay.
Preventing tooth decay isn't a "one-size-fits-all" approach. By identifying your own particular risk, we can craft a care strategy that can be your best defense against this destructive dental disease.
Finding out you have a cavity isn't the best of news. But finding out it's a root cavity is even worse: if not treated, the decay can spread more rapidly than a cavity occurring in the tooth's crown surfaces.
Our teeth are basically composed of two parts: the crown, the visible tooth above the gum line, and the roots, the hidden portion beneath the gums. The root in turn fits into a bony socket within the jaw to help hold the tooth in place (along with attached gum ligaments).
A tooth crown is covered by an ultra-hard layer of enamel, which ordinarily protects it from harmful bacteria. But when acid produced by bacteria comes into prolonged contact with enamel, it can soften and erode its mineral content and lead to a cavity.
In contrast to enamel, the roots have a thin layer of material called cementum. Although it offers some protection, it's not at the same performance level as enamel. But roots are also normally covered by the gums, which rounds out their protection.
But what happens when the gums shrink back or recede? This often occurs with gum disease and is more prevalent in older people (and why root cavities are also more common among seniors). The exposed area of the roots with only cementum standing in the way of bacteria and acid becomes more susceptible to cavity formation.
Root cavities can be treated in much the same way as those that occur in the crown. We first remove any decayed tooth structure with a drill and then place a filling. But there's also a scenario in which the cavity is below the gum line: In that case, we may need to gain access to the cavity surgically through the gums.
If you have exposed root areas, we can also treat these with fluoride to strengthen the area against cavity formation. And, as always, prevention is the best treatment: maintain a daily schedule of brushing and flossing and regular dental cleanings to remove bacterial plaque.
Because decay can spread within a tooth, dealing with a root cavity should be done as promptly as possible. But if we diagnose and initiate treatment early, your chances of a good outcome are high.

Between the final game of the World Series in late October and spring training in February, major league baseball players work on their skills preparing for the new season. Reporters on a Zoom call to the New York Yankees' training camp wanted to know what star outfielder Aaron Judge had been doing along those lines. But when he smiled, their interest turned elsewhere: What had Aaron Judge done to his teeth?
Already with 120 homers after only five seasons, Judge is a top player with the Yankees. His smile, however, has been less than spectacular. Besides a noticeable gap between his top front teeth (which were also more prominent than the rest of his teeth), Judge also had a chipped tooth injury on a batting helmet in 2017 during a home plate celebration for a fellow player's walk-off home run.
But now Judge's teeth look even, with no chip and no gap. So, what did the Yankee slugger have done?
He hasn't quite said, but it looks as though he received a “smile makeover” with porcelain veneers, one of the best ways to turn dental “ugly ducklings” into “beautiful swans.” And what's even better is that veneers aren't limited to superstar athletes or performers—if you have teeth with a few moderate dental flaws, veneers could also change your smile.
As the name implies, veneers are thin shells of porcelain bonded to the front of teeth to mask chips, cracks, discolorations or slight gaps between teeth. They may even help even out disproportionately sized teeth. Veneers are custom-made by dental technicians based on a patient's particular tooth dimensions and color.
Like other cosmetic techniques, veneers are a blend of technology and artistry. They're made of a durable form of dental porcelain that can withstand biting forces (within reason, though—you'd want to avoid biting down on ice or a hard piece of food with veneered teeth). They're also carefully colored so that they blend seamlessly with your other teeth. With the right artistic touch, we can make them look as natural as possible.
Although porcelain veneers can accommodate a wide range of dental defects, they may not be suitable for more severe flaws. After examining your teeth, we'll let you know if you're a good candidate for veneers or if you should consider another restoration. Chances are, though, veneers could be your way to achieve what Aaron Judge did—a home run smile.
