For several decades, dentists have been saving teeth from tooth decay following a few basic guidelines: 1) Identify decay as soon as possible; 2) Thoroughly remove decayed tooth structure; and 3) Fill any cavities. With millions of diseased teeth rescued, observing these simple steps have proven a rousing success.
But as with most things, even this successful protocol isn't perfect. For one, some healthy tissue gets removed along with the diseased portions. The average percentage of "collateral damage" has dropped over the years, but it still happens—and a reduction in healthy tissue can make a tooth less structurally sound.
Another drawback, at least from the patient's perspective, is the dental drill used for removing decay and preparing cavities for filling. Many people find drilling unpleasant, whether from its vibrations in the mouth or its high-pitched whine. The drill's burr head design also contributes to greater healthy tissue loss.
But those weaknesses have lessened over the last few years, thanks to innovations on a number of fronts.
Better risk management. Tooth decay doesn't occur out of thin air—it arises out of risk factors unique to an individual patient like personal hygiene, bacterial load, saliva production or even genetics. Taking the time to identify a patient's "tooth decay risk score" can lead to customized treatments and practices that can minimize the occurrence of decay.
Earlier detection. Like other aspects of dental health, the sooner we detect decay, the less damage it causes and the more successful our treatment. X-rays remain the workhorse for detecting decay, but now with improvements like digital film and better equipment. We're also using newer technologies like laser fluorescence and infrared technology that can "see" decay that might otherwise go undetected.
Less invasive treatment. The dental drill is now being used less with the advent of air abrasion technology. Air abrasion utilizes a concentrated spray of particles to remove diseased tooth structure more precisely than drilling. That means less healthy tissue loss—and a more pleasant (and quieter!) experience for the patient.
In effect, "less is more" could describe these improvements to traditional decay treatment. They and other methods promise healthier teeth and happier patients.

From birth to early adulthood, your child's teeth, gums and jaws develop at a rapid pace. And, for the most part, nature takes its course without our help.
But tooth decay can derail that development. The result of bacterial acid eroding enamel, tooth decay is the top cause for premature primary tooth loss in children. One particular form, early childhood caries (ECC), can rapidly spread from one tooth to another.
Many parents assume prematurely losing teeth that are destined to fall out soon anyway is inconsequential. But primary teeth play a critical role in the proper eruption of permanent teeth, serving as both placeholders and guides for those teeth developing just below them in the gums. A permanent tooth without this guidance can erupt out of alignment to create a poor bite that may require future orthodontics.
Being proactive about tooth decay lessens that risk—and the best time to start is when the first teeth begin to erupt. That's when you should begin their regular dental visits sometime around their first birthday.
Dental visits are an important defense against tooth decay. Besides routine dental cleanings, your child's dentist can offer various preventive treatments like sealants to stop decay from forming in the biting surfaces of back molars or topically applied fluoride to strengthen tooth enamel.
Daily home care is just as important in the fight against tooth decay. Oral hygiene should be a part of your child's daily life even before teeth: It's a good habit to wipe an infant's gums with a clean cloth after nursing. As teeth arrive, oral hygiene turns to brushing and flossing—perhaps the best defense of all against dental disease.
It's also important to watch their intake of sugar, a prime food source for bacteria that produce harmful acid. Instead, encourage a "tooth-friendly" diet of whole foods to keep teeth and gums healthy.
Even if they do develop tooth decay, there are effective treatments to minimize any damage and preserve affected primary teeth until they've served their purpose. By adopting these prevention strategies and prompt treatment, you can stay ahead of this destructive disease.
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.
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.
