Tooth decay doesn't occur out of thin air, but is the end result of bacteria feeding on sugar, multiplying and producing acid. High acidity erodes tooth enamel and creates an environment for cavity development.
Modern dentistry can effectively treat cavities and often save the tooth from further damage. But you don't have to wait: You can reduce your chances of cavities by managing risk factors that contribute to decay.
Here are 4 top risk factors for tooth decay and what you can do about them.
Poor saliva flow. Saliva neutralizes acid and helps restore minerals to enamel after acid contact. But your enamel may not have full protection against acid if you have diminished saliva flow, often due to certain medications. You can help increase your saliva by consulting with your doctor about drug alternatives, drinking more water or using a saliva boosting product. Smoking can also inhibit saliva, so consider quitting if you smoke.
Eating habits. High sugar content in your diet can increase bacterial growth and acid production. Reducing your overall sugar consumption, therefore, can reduce your risk of decay. Continuous snacking can also increase your decay risk, preventing saliva from bringing your mouth back to its normal neutral pH. Instead, limit your snack periods to just a few times a day, or reserve all your eating for mealtimes.
Dental plaque. Daily eating creates a filmy buildup on the teeth called dental plaque. If not removed, plaque can then harden into a calcified form called calculus, an ideal haven for bacteria. You can help curtail this accumulation by thoroughly brushing and flossing daily, followed by dental cleanings at least every six months. These combined hygiene practices can drastically reduce your cavity risk.
Your genetics. Researchers have identified up to 50 specific genes that can influence the risk for cavities. As a result, individuals with similar dietary and hygiene practices can have vastly different experiences with tooth decay. Besides continuing good lifestyle habits, the best way to manage a genetic disposition for dental disease is not to neglect ongoing professional dental care.

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.

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 oral disease, which along with periodontal (gum) disease is most responsible for tooth loss. And as you age, your disease risk goes up.
One form of decay older people often experience is root cavities. Unlike those occurring in the visible crown, root cavities often occur below the gum line and are especially destructive to tooth structure.
That's because, unlike the crown protected by ultra-hard enamel, the roots are covered by a thin, mineralized material called cementum. Although cementum offers some protection, it can't compare with the decay-resistant capacity of enamel.
The roots also depend on gum coverage for protection. But unfortunately, the gums can shrink back or recede, usually due to gum disease or over-aggressive brushing, and expose some of the root surface. With only the cementum to protect them, the roots can become highly susceptible to decay. If a cavity forms here, it can rapidly advance into the tooth's interior, the pulp, weakening the tooth and increasing its risk of loss.
To stop the decay, we must treat root cavities much like we do with crown cavities: by removing any decayed structure and then filling the cavity. But root cavities are often more difficult to access depending on how far below the gum line they extend. We may need to perform minor gum surgery to expose the cavity to treat it.
But as with any form of tooth decay, the best strategy is to prevent root cavities in the first place. Your first line of defense is a daily hygiene habit of brushing and flossing to remove dental plaque, the main cause for tooth decay. You should also visit your dentist at least twice a year (or more, if recommended) for more thorough cleanings and checkups. Your dentist can also recommend or prescribe preventive rinses, or apply fluoride to at-risk tooth surfaces to strengthen them.
You should also be on the lookout for any signs of gum disease. If you see swollen, reddened or bleeding gums, see your dentist as soon as possible. Stopping possible gum recession will further reduce your risk of root cavities.

Dental caries (tooth decay) is a leading cause of tooth loss. But with prompt diagnosis and care we can often stop it before it causes too much damage.
The traditional treatment approach is simple: remove all diseased tooth structure and then restore the tooth with a filling. But this otherwise effective treatment has one drawback: you may lose significant healthy structure to accommodate a suitable filling or to make vulnerable areas easier to clean from bacterial plaque.
That's why a new treatment approach called minimally invasive dentistry (MID) is becoming more common. The goal of MID is to remove as little of a tooth's natural enamel and dentin as possible. This leaves the treated tooth stronger and healthier, and could reduce long-term dental costs too.
Here's how MID could change your future dental care.
Better risk assessment. MID includes a treatment protocol called caries management by risk assessment (CAMBRA). With CAMBRA, we evaluate your individual tooth decay risk, including oral bacteria levels, the quality of saliva flow to neutralize mouth acid, and sugar consumption. We then use our findings to customize a treatment plan that targets your areas of highest risk.
New detection methods. The real key to fighting tooth decay is to find it before it can destroy tooth structure with the help of new diagnostic technology. Besides advances in x-ray imaging that provide better views with less radiation exposure, we're also using powerful dental microscopes, lasers and infrared photography to show us more about your teeth than we can see with the naked eye.
"Less is More" treatments. In contrast to the dental drill, many dentists are now using air abrasion rather than a dental drill to remove decayed tooth material. Air abrasion emits tiny material particles within a pressurized air stream that leaves more healthy tooth structure intact than with drilling. We're also using new filling materials like composite resin that not only resemble natural tooth color, but require less structural removal than other types of fillings.
Using MID, we can treat tooth decay while preserving more of your natural teeth. This promises better long-term outcomes for future dental health.
