Have you heard about dental sealants? These preventive treatments have been available for many decades, and more and more children are taking advantage of them. The National Institutes of Health (NIH) estimates that around 30% of kids from 6 to 11 years of age have had sealants applied to their molars (back teeth). Sealants are designed to reduce the incidence of cavities by filling in or eliminating the pits or crevices found in all molars, where decay-causing bacteria can hide and your brush can't reach. But do they really work?
Now, the research is in, and the answer is clear — YES!
Two major studies, each of which reviewed the results of thousands of patients over several years, recently came to the same conclusion: Dental sealants are effective at reducing cavities, and their benefits can last for four years (or more) after application. In general, the studies showed that kids who didn't get sealants were twice, three times, or even more likely to get cavities, compared to kids treated with sealants.
Sealants themselves are protective coatings made of plastic resins or glass-like materials. They are applied in liquid form, and then hardened by a special light. When “painted on” to the chewing surface of a molar, sealants fill in the tiny crevices, or “pits and fissures,” that are found there. Uneven tooth surfaces form a perfect breeding ground for the bacteria that cause tooth decay; worse yet, the bristles of a tooth brush can't usually reach them. That's what makes these areas highly susceptible to tooth decay.
Applying sealants is a quick and painless procedure that doesn't require any numbing shots or drilling. Many kids start getting sealants when the first permanent molars come in, around age 5 to 7; they may have more sealant treatments when additional molars emerge, between the ages of 11 and 14.
Sealants are recommended by the American Dental Association and the American Academy of Pediatric Dentistry, and have only a modest cost per tooth. On the other hand, having a cavity filled generally costs substantially more, and may result in more trouble (and expense) down the line — so sealants can make sense economically, as well as preventively. This is especially true for those at high risk for tooth decay.

So, you've undergone a root canal treatment to save a decayed tooth. The tooth has a new lease on life — and the pain is gone too. But there's a reality you need to keep in mind — your tooth could become re-infected, putting you back in the same painful circumstance.
Root canal treatments are often necessary when decay works its way deep within a tooth, into the pulp. The excruciating pain a person feels is the infection attacking the bundle of nerves within the pulp tissue. If the infection isn't addressed promptly, it will continue to work its way to the root, eventually damaging the tooth beyond repair.
During a root canal treatment, we drill into the tooth to access the pulp chamber. After clearing it completely of its infected tissue, we then fill the chamber and root canals with a special filling and then seal off the access. A short time later we'll bond a crown over the tooth to protect it and to make it more attractive.
Most of the time, this preserves the tooth for many years. Occasionally, though, re-infection can occur. There are a number of reasons why: the first infection may have been more extensive than thought; the root canal network was more complex and some tinier canals weren't able to be identified; or the protective crown may once again get tooth decay contaminating the root canal.
If infection does reoccur it doesn't mean the tooth is lost. It's possible a second root canal treatment can successfully correct any problems, especially those that may not have been detected the first time. More complex cases might also require the services of an endodontist, a specialist in root canals. They're skilled in advanced techniques and have specialized equipment to handle even the most complicated root canal networks.
In the meantime, if you notice signs of re-infection like pain or swelling around a treated tooth, contact us promptly for an appointment. You should also contact us if the tooth is injured in an accident. The sooner we can treat your tooth, the more likely the second time will be more successful.
