What is root canal therapy? Root canal treatment is performed to save a tooth when its nerve becomes injured or infected. A tooth with a damaged nerve can become immensely painful if left untreated. Root canal treatment removes the damaged nerve and replaces it with a sterile, inert material.
How long does it take? Commonly, root canal treatment is performed in either one or two visits.
Is it painful? Because of changes in dental anesthetics and strategies, the old stereotypical treatment of the terrible root canal is a relic of days gone by. Most patients report practically no distress throughout procedure.
After a root canal is anything else required? Most teeth that require a root canal must be permanently sealed with a dental crown.
