As in other parts of medicine, lasers are beginning to change the way we provide dental care. More and more dentists are using lasers to make earlier diagnoses of dental disease or provide surgical treatment. One area prime for change is the treatment of teeth with deep decay and in danger of being lost.
For decades now, the best way to save teeth in this condition is with root canal treatment. In this common procedure we access the pulp, remove the infected tissue with specialized hand instruments, and then fill and seal the pulp chamber and root canals with a special filling.
We can now potentially improve the efficiency and increase the success rate of this treatment with laser technology. With their focused light, lasers emit a concentrated burst of energy that's extremely precise. In many instances laser energy can remove the target diseased tissue without damaging nearby healthy tissue.
In this form of root canal treatment, we use lasers to remove tissue and organic debris within the pulp and then shape the root canal walls to better receive the filling. We can also utilize the heat from laser energy to soften and mold the filling, so that it better conforms within the walls of the root canals.
Using lasers in root canal treatments may require less local anesthesia than the traditional approach and also eliminates disturbing or discomforting sounds and vibrations. Dentists who've used the new technology also report less bleeding during the procedure and less pain and occurrences of infection afterwards.
But there are a couple of disadvantages for using lasers in root canal treatment. For one, light travels in a straight line — and many root canal networks are anything but straight. More complex root canal networks may still require the traditional approach. Laser energy could also increase the tooth's inner temperature, which could potentially damage tissues even on the tooth's outer surfaces.
Used in the right circumstances, though, lasers can be an effective means to treat diseased teeth. Â As laser technology continues to advance and becomes a mainstay in dental care, you may soon find it part of your next dental procedure.
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.
