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.
One of the most effective techniques for saving decayed or injured teeth is the root canal treatment. Yet when many people hear they need it, they become nervous at the prospect.
Much of this stems from a common misunderstanding that undergoing a root canal is painful. It’s not — today’s anesthetics are quite effective in numbing pain during a procedure, and mild pain relievers like ibuprofen are usually sufficient to manage any discomfort afterwards.
In fact, a root canal treatment relieves pain caused by decay within a tooth. As decay progresses, it can enter the interior known as the pulp, which contains bundles of nerves and blood vessels. It attacks these nerves causing pain and infection. If the infection progresses through passageways known as root canals that are in the roots of the tooth, the pain can intensify. More important, the tooth is in danger of loss as the root and connective tissues that hold the tooth in place are injured from the spreading infection.
During a root canal treatment, we access the pulp by drilling a small access hole, usually in the biting surface or in the rear of a front tooth. Once we enter the pulp chamber we remove all the contaminated tissue. Once thoroughly cleansed, we fill the empty chamber and canals with a special filling (usually gutta percha) to prevent future infection. The access hole is then sealed and at a subsequent visit we strongly recommend placing a permanent crown to provide further protection from damage to the tooth.
Root canal treatments are quite common. All general dentists have been trained in endodontic treatment and can perform most types of procedures. More difficult cases (like a complex root canal network that may be hard to access) may require the services of an endodontist, a specialist in root canals. Endodontists use advanced techniques and specialized microscopic equipment to treat complicated situations.
It’s actually good news if we recommend you undergo a root canal treatment — it means your tooth has a good chance of survival once it’s disinfected and the decay is removed. But don’t delay: the sooner we can treat your tooth, the better your chances of a healthy outcome.
