Root Canal Treatment
Patients typically need a root canal when there is inflammation or infection in the roots of a tooth.
An endodontist who specializes in such treatment carefully removes the pulp inside the tooth, cleans, disinfects and shapes the root canals, and places a filling to seal the space.
It is possible for a root canal tooth to heal improperly, becoming painful or diseased months or even years after treatment. In that case you have the chance to save the tooth with a retreatment.
