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.
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.

Even after decades emphasizing oral hygiene and supplemental fluoride to fight dental disease, we’re now seeing an increase in tooth decay, especially among children. What’s causing this alarming trend?
Many in both the dental and medical professions link this and other health problems to a rise in the amount and consumption of sugar added to food products. A number of years ago our annual average consumption of added sugar was about 4 pounds per person; today, it’s closer to 90 pounds.
The increase in sugar consumption can be traced to the 1970s when the food industry began adding more sugar to make processed foods stripped of oils and fats taste better. Today, 77% of the approximately 600,000 food items sold in the United States contain some form of sugar (under a variety of names).
This additional sugar, however, has produced an unintended consequence: sugar triggers the release of a brain chemical called dopamine that regulates our sense of reward when we engage in a desirable behavior. The excess dopamine creates a weak addiction to sugar, which then leads to overconsumption, contributing to our current obesity epidemic and the rise in health problems like heart disease or Type 2 diabetes. This is especially alarming among children: thirty years ago Type 2 diabetes was unheard of among children — today there are over 55,000 diagnosed pediatric cases.
For both you and your family’s general and dental health, you should consider ways to reduce your sugar intake: purchase and eat most of your food from the “outer edges” of your supermarket — meats, dairy, and fresh vegetables and fruits (which do contain the sugar fructose, but are mostly fiber that slows the liver’s processing of the sugar); limit processed foods with added sugar, and learn to recognize its inclusion in products by reading ingredients labels. You should also be wary of sweetened beverages such as sodas, sports drinks, teas or juices, and try to drink more water.
The recommended daily sugar consumption is less than six teaspoons a day (about two-thirds the amount in one can of soda). By restricting this consumption, you’ll improve your general health and reduce your risk for dental disease.
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.

Nothing grabs your attention like a sharp tooth pain, seemingly hitting you out of nowhere while you’re eating or drinking. But there is a reason for your sudden agony and the sooner you find it out, the better the outcome for your oral health.
To understand tooth sensitivity, we need to first look at the three layers of tooth anatomy. In the center is the pulp filled with blood vessels and nerve bundles: it’s completely covered by the next layer dentin, a soft tissue filled with microscopic tubules that transmit sensations like pressure or temperature to the pulp nerves.
The third layer is enamel, which completely covers the crown, the visible part of a tooth. Enamel protects the two innermost tooth layers from disease and also helps muffle sensations so the tooth’s nerves aren’t overwhelmed. The enamel stops at about the gum line; below it the gums provide similar protection and sensation shielding to the dentin of the tooth roots.
Problems occur, though, when the dentin below the gums becomes exposed, most commonly because of periodontal (gum) disease. This bacterial infection caused by dental plaque triggers inflammation, which over time can weaken gum tissues and cause them to detach and shrink back (or recede) from the teeth. This can leave the root area vulnerable to disease and the full brunt of environmental sensations that then travel to the nerves in the pulp.
Tooth decay can also create conditions that cause sensitivity. Decay begins when certain oral bacteria multiply and produce higher than normal levels of acid. The acid in turn dissolves the enamel’s mineral content to create holes (cavities) that expose the dentin. Not treated, the infection can eventually invade the pulp, putting the tooth in danger of being lost unless a root canal treatment is performed to remove the infection and seal the tooth from further infection.
So, if you begin experiencing a jolt of pain while eating or drinking hot or cold foods or beverages, see your dentist as soon as possible to diagnose and treat the underlying cause. And protect your teeth from dental disease by practicing daily brushing and flossing, as well as seeing your dentist for regular dental cleanings and checkups. Don’t ignore those sharp pains—your teeth may be trying to tell you something.
