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.

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.
