Root canal treatment is used to repair and save a tooth that is decayed or badly infected. During a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned and sealed.

Apicectomy is a surgical procedure to remove the tip of the root of a root canal of a treated (or non-vital) tooth and then sealed with a filling. Root Canal Surgery is used to treat persistent symptoms not responding to previous non-surgical treatment or previous root canal surgery which has not resolved the problem or calcified root canals
