What is root canal treatment (RCT)?
A tooth, which has been damaged by caries or injury to the extent that the nerve of the tooth has been involved, cannot be simply filled. The procedure to remove the damaged nerve and infection from the root canal and surrounding bone is called root canal treatment. If the tooth is vital or partially vital the first sitting of root canal requires administration of local anesthesia. It may be a single sitting or a multi-sitting procedure and invariably the tooth needs to be caped later.
