A root canal is a treatment used to repair and save a tooth that is badly decayed or infected. During a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned and sealed. “Root canal” is the term used to describe the natural cavity within the center of the tooth. The pulp or pulp chamber is the soft area within the root canal. When you undergo a root canal or other endodontic treatment, the inflamed or infected pulp is removed and the inside of the tooth is carefully cleaned and disinfected, then filled and sealed with a rubber like material. These entire procedure can be done in a single visit. Afterwards, the tooth is restored with a crown or filling for protection and will continue to function like any other tooth
