Endodontic therapy or root canal therapy is a treatment of the pulp or nerve of the tooth. The pulp is removed from the tooth, the canals reshaped and filling material such as Gutta Percha placed. After a root canal procedure the tooth will be considered “dead.”
A tooth may need a Root Canal if there is infection of the nerve (often caused from tooth decay), or if the tooth has undergone enough trauma that symptoms remain for a long period of time.
In severe cases, formation of an abscess and swelling can occur, causing extreme discomfort. Your dentist may put you on a prescription of antibiotics prior to doing the Root Canal in order to allow for proper freezing of the area. This is a temporary solution only and if the procedure is not completed the symptoms are likely to return.
