Root canal treatments are an essential part of dental care — countless teeth with deep decay would be lost each year without it. Now, this traditional dental care procedure is advancing to a new level of precision through lasers.
Root canal treatments have a simple goal: access a tooth's infected pulp and root canals, clean out the infected tissue and fill the empty pulp chamber and canals with a special filling. Once filled, the access is sealed and a porcelain crown later placed for additional protection against re-infection.
In the traditional procedure, we perform these steps manually with a dental drill and hand instruments. We may also need to remove a good portion of tooth structure, both healthy and infected tissue. A laser, on the other hand, is a highly focused beam of light with the ability to interact with healthy and infected tissues differently: destroying infected tissue while having no effect on nearby healthy tissue. The end result: we may be able to remove less healthy tissue with lasers than with the conventional procedure.
Lasers are also helpful with softening and precisely molding the filling material within each canal's particular shape. And, early reports seem to indicate a higher degree of comfort for patients (less drill noise and need for anesthesia), less bleeding and faster recovery times than the conventional approach.
But as a tool for root canal treatments, lasers do have a couple of disadvantages. While light travels in a straight line, root canals are rarely straight — conventional instruments with curved designs usually accommodate odd canal shapes better than a laser. Lasers can also raise temperatures within a tooth that can damage healthy tissue, both within the pulp and outward into the dentin.
Still, lasers for root canal treatments appear promising with some dentists using a combination of lasers and manual techniques to garner benefits from both approaches. While you won't see lasers replacing the traditional root canal treatment anytime soon, the future looks bright for more efficient ways to treat deep tooth decay.
If a pain you’ve been feeling goes away, you might believe the problem that caused it is gone too. But that doesn’t mean it has, especially with a tooth. An excruciating toothache that suddenly stops should still be examined. Here’s why.
Tooth decay often works its way into a tooth’s innermost layer, the pulp, which contains bundles of nerves and other tissue. The infection attacks the nerves, which send pain signals to the brain. As the infection persists, though, the nerves will eventually die and will no longer be capable of sending pain signals — hence the “mysterious” end of your toothache.
Although the pain has stopped, the infection is very much active in the tooth and will continue to work its way through the root canals to the jaw. And ultimately, the pain will return as the infection invades the bone.
But there’s good news: a tooth in this condition can be saved with a procedure known as root canal therapy. We drill a small hole in the tooth to access the pulp, usually through the biting surface of back teeth or in the rear in front teeth. Once inside the pulp chamber, we clean out the infected and dead tissue. We then fill the empty pulp chamber and the root canals with a special filling and seal the access hole. In a few weeks the tooth receives a life-like crown to further protect it from re-infection and fracture years later.
A straightforward root canal treatment can be performed by a general dentist. If there are complications like a complex root canal network, however, then the skills and specialized equipment of an endodontist (a specialist in root canals) may be needed.
A root canal treatment resolves the real cause of a toothache that suddenly stopped, as well as puts an end to future pain and infection related to the tooth. More importantly, it can save your tooth and add many more years to its life.
