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.

Tooth decay is one of two dental diseases most responsible for tooth loss (gum disease being the other). In the absence of treatment, what starts as a hole or cavity in a tooth's outer layers can steadily advance toward its interior.
Most people associate cavities with the crown, the part of a tooth you can see. But cavities can also occur in a tooth's roots, especially with older adults. Root cavities pose two distinct difficulties: They can lead to more rapid decay spread than crown cavities within a tooth; and they're harder to detect.
Tooth roots are ordinarily covered by the gums, which protects them from bacterial plaque, the main cause for decay. But roots can become exposed due to receding gums, a common problem with seniors who are more susceptible to gum disease.
Unlike the enamel-covered crowns, tooth roots depend on gum coverage for protection against bacteria and the acid they produce. Without this coverage, the only thing standing between tooth decay and the roots is a thin material called cementum.
If decay does enter a tooth's interior, saving it often requires a root canal treatment to remove decayed tissue in the inner pulp and root canals, and then replacing it with a filling. But if we're able to discover a root cavity in its early stages, we may be able to fill it like a crown cavity.
The best strategy, though, is to prevent root cavities from forming. This starts with a dedicated daily regimen of brushing and flossing to remove dental plaque. If you're at high risk for root cavities, we may also recommend antibacterial mouthrinses and other aids.
Regular dental visits are also a must: a minimum of twice-a-year dental cleanings to remove stubborn plaque and calculus (hardened plaque) deposits. For added protection against root cavities, we can also apply fluoride varnish to strengthen teeth. And regular visits are the best way to detect any cavity in its early stages when treatment is less invasive.
A heightened risk of dental problems like root cavities are a part of the aging process. But partnering together, we can lower that risk and increase the longevity of your teeth.

Advanced tooth decay is a serious dental problem that can threaten an affected tooth's survival. But for decades now dentists have reliably used root canal treatment to better a decayed tooth's odds. This routine procedure performed with dental drill and special hand tools removes infected tissue inside a tooth and replaces the voids with a filling to prevent future infection.
But now there's a new way to perform a root canal—with a surgical laser. Lasers, amplified and focused light beams, aren't new to healthcare—they're an integral feature of many routine medical treatments and surgeries. But their use is relatively new to dentistry, and to endodontics (treating the interior of teeth) in particular.
Lasers can be used in root canal treatment to perform a number of tasks. They can remove diseased tissue and other debris from the innermost tooth pulp. They can be used to clean and shape root canal walls in preparation for filling. And they can also be used to soften and mold the filling material to fit more precisely within a tooth's particular root canal network.
Although laser-assisted root canal therapy isn't yet widespread, laser's limited use to date has given us a fair picture of both their advantages and disadvantages. As with other medical laser applications, lasers are very precise in removing diseased tissue without too much disruption of healthy tissue. There's less need for anesthesia than with dental drills, and lasers are a lot less noisy and jarring. Patients by and large experience less bleeding, as well as less discomfort or infection afterward.
But because laser light can only travel in a straight line, they're difficult to use in many tightly curved root canals. In these cases, the traditional methods are better suited, although a laser can be used in conjunction with other tasks. Temperature with lasers must also be carefully managed lest the high heat that's often generated damages natural tissues.
Although lasers won't be replacing traditional treatment methods for decayed teeth in the foreseeable future, there's hope they'll become more commonplace as technology and techniques continue to advance. Lasers can only improve what already is an effective means of saving teeth.

Over the last century dentistry has acquired the knowledge, techniques and treatments to prevent or minimize tooth decay. With this enhanced knowledge we’ve amassed a wealth of data about what increases dental disease development and what prevents it.
This has produced a balanced approach to identifying and treating disease-causing factors and incorporating factors that inhibit tooth decay. Known as Caries Management By Risk Assessment (CAMBRA), this approach first identifies each patient’s individual set of risk factors for dental disease and then develops a customized prevention and treatment plan to minimize their risk.
Rather than simply reacting to occurrences of tooth decay — “drill and fill” — CAMBRA anticipates and targets your susceptibility to decay. The primary factors can be represented by the acronym BAD: Bad bacteria, particular strains that produce acid, which at high levels erode enamel and expose the teeth to infection; Absence of saliva, or “dry mouth,” an insufficient flow of saliva that can’t effectively neutralize acid and restore mineral content to enamel; and Dietary habits too heavy in sugar or acid, which can result in bacterial growth and enamel erosion.
With an accurate picture of your particular risk level we can then apply countering factors from the other side of the balance — those that protect teeth from decay. In this case, we use the acronym SAFE: stimulating Saliva flow when needed or applying Sealants on chewing surfaces most susceptible to decay; Antimicrobials that reduce unhealthy bacteria levels and give healthy bacteria an opportunity to thrive; incorporating Fluoride, a chemical known to strengthen enamel, through hygiene products or direct application to the teeth; and an Effective diet, low in sugar and acid and high in fresh fruits, vegetables and whole grains.
There are a number of preventive and treatment measures that fall into each of the four preventive factors. Using the CAMBRA approach we can develop a treatment and prevention plan that incorporates measures that uniquely fit your dental health situation. With such a plan we can greatly reduce your risk of disease development and impact and better ensure a long and healthy life for your teeth and gums.

More than likely your great-grandparents, grandparents and even your parents had a common dental experience: when one of their teeth developed a cavity, their dentist removed the decayed portion (and maybe a little more) through drilling and then filled the cavity. In other words, treatment was mainly reactive—fix the problem when it occurred, then fix it again if it reoccurred.
You may have had similar experiences—but the chances are good your dentist’s approach is now quite different. Today’s tooth decay treatment is much more proactive: address first the issues that cause tooth decay, and if it does occur treat it with an eye on preventing it in the future.
This approach depends on maintaining equilibrium between two sets of competing factors that influence how your teeth may encounter tooth decay. This is known as the caries balance (caries being another name for tooth decay). On one side are factors that increase the risk of decay, known by the acronym BAD: Bad Bacteria that produce acid that dissolves the minerals in tooth enamel; Absence of Saliva, the body’s natural acid neutralizer; and Dietary Habits, especially foods with added sugars that feed bacteria, and acid that further weakens enamel.
There are also factors that decrease the risk of tooth decay, known by the acronym SAFE: Saliva and Sealants, which focuses on methods to boost low salivary flow and cover chewing surfaces prone to decay with sealant materials; Antimicrobials, rinses or other substances that reduce bad bacteria populations and encourage the growth of beneficial strains; Fluoride, increased intake or topical applications of this known enamel-strengthening chemical; and Effective Diet, reducing the amount and frequency of sugary or acidic foods and replacing them with more dental-friendly choices.
In effect, we employ a variety of techniques and materials that inhibit BAD factors and support SAFE ones. The foundation for prevention, though, remains the same as it was for past family generations—practice effective oral hygiene by brushing and flossing daily and regular dental cleanings and checkups to keep bacterial plaque from accumulating and growing. Your own diligent daily care rounds out this more effective way that could change your family history of tooth decay for you and future generations.
