Root canal treatment is needed when the nerve of a tooth is affected by decay or infection. In order to save the tooth, the pulp (the living tissue inside the tooth), nerves, bacteria, and any decay are removed and the remaining roots are sealed
Root canal therapy allows you to keep your natural tooth and continue using it as before. Many patients believe that removing a problematic tooth is the solution, but removing a tooth will ultimately be more costly and may cause significant problems for adjacent teeth.
Root canal treatment is highly successful and usually lasts a lifetime, though on occasion, a tooth will have to be retreated due to new infections.
