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.
Since the late 19th Century, dentists have used established protocols to successfully prevent and treat tooth decay. But there've been changes to this approach the last few years to improve its effectiveness, changes we now refer to as Minimally Invasive Dentistry or MID.
The older approach for treating dental caries (tooth decay) follows the protocols established by Dr. G.V. Black, considered the father of modern dentistry. Black advocated removing not only decayed structure but also some of the healthier but vulnerable portions of a tooth, to avoid further decay and make the tooth easier to clean. This resulted in larger fillings, although they've become smaller as dental techniques have advanced.
MID, on the other hand, aims to remove as little tooth structure as possible while still effectively treating and preventing future decay. To achieve that goal we begin first with a complete assessment of a patient's individual decay risk, known as Caries Management By Risk Assessment (CAMBRA).
With CAMBRA, we're looking at other factors besides individual tooth health: a patient's hygiene, lifestyle and dietary habits; the types and amount of bacteria present; and the quality of saliva flow, needed to neutralize mouth acid. With these the results we develop a customized prevention and treatment strategy.
MID also focuses on detecting dental caries as early as possible. Besides traditional x-rays, we're beginning to use other methods like dental microscopes, laser fluorescence, infrared photography or optical scanning. Early detection leads to early intervention, and with techniques that are much less invasive than the traditional approach.
The new approach also changes how we repair decayed teeth. We're increasingly using air abrasion, a technology that uses fine particles in a pressurized air stream to remove softer decayed tooth material and less healthy structure than the traditional dental drill. We're also using composite resin and other advanced materials for filings: these tooth-colored materials are stronger than previous versions and are quickly taking the place of metal amalgam, requiring less structural removal to accommodate them.
MID's core principles are early disease detection, proactive prevention and treatment with less structural removal. With this enhanced approach to effective dentistry, we're keeping your teeth healthy with minimal discomfort, lower costs and less long-term impact.
Tooth decay is a destructive disease that could rob you of your teeth. But it doesn't appear out of nowhere—a number of factors can make it more likely you'll get cavities.
But the good news is you can be proactive about many of these factors and greatly reduce your risk of tooth decay. Here are a few questions to ask yourself to point you in the right direction for preventing this destructive disease.
Do you brush and floss every day? A daily habit of brushing and flossing removes buildup of dental plaque, a bacterial film on teeth that's the top cause for tooth decay and periodontal (gum) disease. Hit or miss hygiene, though, can greatly increase your risk for developing a cavity.
Do you use fluoride? This naturally occurring chemical has been proven to strengthen tooth enamel against decay. Many locations add fluoride to drinking water—if your area doesn't or you want to boost your fluoride intake, use toothpastes, mouthrinses or other hygiene products containing fluoride.
Do you smoke? The nicotine in tobacco constricts blood vessels in the mouth so that they provide less nutrients and antibodies to the teeth and gums. Your mouth can't fight off infection as well as it could, increasing your risk of dental diseases like tooth decay.
Do you have dry mouth? This isn't the occasional bout of “cotton mouth,” but a chronic condition in which the mouth doesn't produce enough saliva. Saliva neutralizes mouth acid, so less of it increases your risk for decay. Chronic dry mouth can be caused by medications or other underlying conditions.
Do you snack a lot between meals? Sugary snacks, sodas or energy drinks can increase oral bacteria and acidity that foster tooth decay. If you're snacking frequently between meals, your saliva's acid neutralizing efforts may be overwhelmed. Coordinate snacking with mealtimes to boost acid buffering.
You can address many of these questions simply by adopting a daily habit of brushing and flossing, regular dental cleanings and checkups, and eating a healthy, “tooth-friendly” diet. By reducing the risk factors for decay, you can avoid cavities and preserve your teeth.

Tooth decay can be a big problem for children's primary (baby) teeth. It doesn't take long for a tooth to become infected and the infection spread to their neighbors.
But since it will eventually give way to a permanent tooth, why not just pull a diseased primary tooth? Although that sounds sensible, there are important reasons for helping a troubled primary tooth survive to its natural end.
Current usefulness. They may not be around for long, but primary teeth serve children well while they have them. They enable a child to eat solid foods to further their physical development. They also figure prominently in speech development, which could be stunted by lost teeth.
The smile factor. Young children are also honing their social skills, and smiling is an important part of learning to fit in with family and friends. A tooth that's missing for some time, especially in the “smile zone,” could affect their smile and have an adverse effect on their social development.
Future teeth health. A primary tooth reserves the space intended for the future permanent tooth, helping to ensure the incoming tooth erupts in the right position. If it's not there, however, other teeth can drift into the space, crowding the incoming tooth out of its proper alignment.
That last reason could have the most long-term effect, causing the development of a poor bite that could require extensive orthodontic treatment. To avoid this and any other physical or social consequences accompanying its premature loss, it's worth the effort to try to protect and save a primary tooth.
Preventively, we can apply sealants on biting surfaces more prone to plaque buildup (the main cause of decay) and topical fluoride to strengthen enamel. When decay does occur, we may be able to remove it and fill the tooth, cap a tooth with a steel crown, or even use a modified root canal procedure in the case of advanced tooth decay.
The best way, however, to protect your child's primary teeth is to brush and floss them every day. Removing harmful plaque vastly reduces the risk of tooth decay. Coupled with professional dental care, your child can avoid tooth decay and get the most out of their primary teeth.

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.
