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.

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.

When decay spreads to the tooth’s inner pulp, a root canal treatment may be necessary to save it. It’s a common procedure: after removing all tissue from the pulp, the pulp chamber and root canals are filled with a special filling. The tooth is then sealed and a crown installed to protect the tooth from re-infection and/or fracture, possibly extending the tooth’s life for many years.
Sometimes, however, the tooth doesn’t respond and heal as expected: the number, size and shape of the patient’s root canals may have complicated the procedure; there may have been a delay before installing the final crown or restoration or the restoration didn’t seal the tooth as it should have, both occurrences giving rise to re-infection. It’s also possible for a second, separate occurrence of decay or injury to the tooth or crown to undo the effects of successful treatment.
It may be necessary in these cases to conduct a second root canal treatment, one that may be more complicated or challenging than the first one. For one thing, if the tooth has been covered by a crown or other restorative materials, these will most likely need to be removed beforehand. In cases where the root canal network and anatomy are challenging, it may require the expertise of an endodontist, a dental specialist in root canal treatments. Using advanced techniques with microscopic equipment, an endodontist can locate and fill unusually narrow or blocked root canals.
Because of these and other possible complications, a root canal retreatment may be more costly than a first-time procedure. Additionally, if you have dental insurance, your particular benefit package may or may not cover the full cost or impose limitations on repeated procedures within a certain length of time. The alternative to retreatment, though, is the removal of the tooth and replacement with a dental implant, bridge or partial denture with their own set of costs and considerations.
The complications and costs of a repeated procedure, though, may be well worth it, if it results in a longer life for the tooth. Preserving your natural tooth is in most cases the most desired outcome for maintaining a healthy mouth.
