Root Canal Therapy

What Is Root Canal Therapy?

Root canal therapy (endodontic treatment) removes the infected or inflamed pulp tissue from inside a tooth, cleans and shapes the root canal system, and seals it to prevent reinfection. The pulp (the soft tissue inside containing nerves and blood vessels) becomes infected through deep decay, a cracked tooth, or repeated dental procedures. Despite its fearsome reputation, a root canal is typically no more uncomfortable than a filling and provides immediate relief from the throbbing pain of pulp infection.

How It Works

After numbing the tooth completely, the endodontist places a rubber dam for isolation, makes an opening in the crown, and removes the pulp with small files. The canals are shaped, disinfected with irrigating solutions, and filled with a rubber-like material (gutta-percha). A temporary or permanent filling closes the access. Most cases require one or two appointments. A crown is usually recommended afterward to protect the treated tooth.
