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.

The basics for treating tooth decay have changed little since the father of modern dentistry Dr. G.V. Black developed them in the early 20th Century. Even though technical advances have streamlined treatment, our objectives are the same: remove any decayed material, prepare the cavity and then fill it.
This approach has endured because it works—dentists practicing it have preserved billions of teeth. But it has had one principle drawback: we often lose healthy tooth structure while removing decay. Although we preserve the tooth, its overall structure may be weaker.
But thanks to recent diagnostic and treatment advances we’re now preserving more of the tooth structure during treatment than ever before. On the diagnostic front enhanced x-ray technology and new magnification techniques are helping us find decay earlier when there’s less damaged material to remove and less risk to healthy structure.
Treating cavities has likewise improved with the increased use of air abrasion, an alternative to drilling. Emitting a concentrated stream of fine abrasive particles, air abrasion is mostly limited to treating small cavities. Even so, dentists using it say they’re removing less healthy tooth structure than with drilling.
While these current advances have already had a noticeable impact on decay treatment, there’s more to come. One in particular could dwarf every other advance with its impact: a tooth repairing itself through dentin regeneration.
This futuristic idea stems from a discovery by researchers at King’s College, London experimenting with Tideglusib, a medication for treating Alzheimer’s disease. The researchers placed tiny sponges soaked with the drug into holes drilled into mouse teeth. After a few weeks the holes had filled with dentin, produced by the teeth themselves.
Dentin regeneration isn’t new, but methods to date haven’t been able to produce enough dentin to repair a typical cavity. Tideglusib has proven more promising, and it’s already being used in clinical trials. If its development continues to progress, patients’ teeth may one day repair their own cavities without a filling.
Dr. Black’s enduring concepts continue to define tooth decay treatment. But developments now and on the horizon are transforming how we treat this disease in ways the father of modern dentistry couldn’t imagine.
The Millennials, those born around the turn of the Millennium in 2000, are entering adulthood. Like any generation, they have their collective promise—and problems. An example of the latter seems to involve their teeth: an estimated one in three people between the ages of 18 and 34 have some form of tooth decay.
If a recent survey is correct, that may be a result of poor oral hygiene practices. The absence of a consistent, daily habit of brushing and flossing to remove disease-causing dental plaque is the number one cause for dental disease. But a survey of 2,000 millennials found only three in ten brushed their teeth at least once a day with many often skipping brushing for two or more days a time.
Interestingly, more than half of the survey also reported an aversion to dental visits. That will likely need to change if these trends in poor hygiene continue, as aging millennials will eventually need extensive treatment for tooth decay and its close counterpart periodontal (gum) disease to save their teeth. Dental professionals recommend a different dental care track: stop dental disease before it develops. And the key to that is a simple but powerful daily brushing and flossing routine.
This routine should involve brushing teeth up to twice and flossing at least once a day. Brushing should be done with gentle strokes, but include all exposed tooth surfaces (about two minutes to perform a thorough job). Flossing is less popular than brushing, but it’s essential for removing plaque between teeth your brush can’t reach. To make it easier, you can use pre-threaded floss or a water flosser that removes plaque with a stream of water.
To round out your prevention strategy, you should see a dentist at least twice a year for professional cleanings of hardened plaque deposits (calculus), as well as overall monitoring of your dental health. And if dental visits make you anxious, your dental professional has a number of ways to help you relax.
One thing’s for sure: like any other generation, millennials prize both good health and an attractive smile. Adopting a solid oral hygiene lifestyle will do the most to achieve both.
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.

Tooth decay is one of the world's most prevalent diseases — and one of the most preventable. We've known the primary prevention recipe for decades: brushing and flossing daily, and dental cleanings and checkups at least twice a year.
But consistent oral hygiene isn't enough — you should also pay attention to your overall health, diet and lifestyle habits. Each of these areas in their own way can contribute to abnormally high mouth acid, which can soften enamel and open the door to tooth decay.
Lower saliva production is one such problem that can arise due to issues with your health. Among its many properties, saliva neutralizes acid and helps maintain the mouth's optimum neutral pH level. But some health conditions or medications can reduce saliva flow: less saliva means less neutralization and chronic acidity.
You can also inhibit saliva flow with one particular lifestyle habit — smoking. Tobacco smoke can damage salivary glands. Nicotine, tobacco's active ingredient, constricts blood vessels, leading to fewer antibodies delivered by the blood stream to mouth tissues to fight disease.
A diet heavy on acidic foods and beverages can also increase mouth acidity. It's not only what you're eating or drinking — it's also how often. If you're constantly snacking or sipping on something acidic, saliva doesn't have a chance to complete the neutralizing process.
In addition to your daily oral hygiene practice, you should also make changes in these other areas to further lower your risk of tooth decay. If you're taking medications that cause dry mouth, see if your doctor can prescribe a different one or try using products that stimulate saliva. Quit smoking, of course, as much for your mouth as for the rest of your health.
On the dietary front, reduce your intake of acidic foods and beverages, especially sodas, energy or sports drinks. If you've counted on the latter for hydration, switch to water instead. And limit acidic foods to mealtime rather than throughout the day.
It's all about maintaining a healthy pH level in your mouth. Doing so along with good oral hygiene will help you better avoid destructive tooth decay.
