Root canal is a treatment used to repair and save a tooth that is badly decayed or becomes infected. During a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned and sealed. Without treatment, the tissue surrounding the tooth will become infected and abscesses may form.

The benefit of this treatment is to remove all infection from the root of the tooth.  The root is cleaned and filled to prevent any further infection.  The alternative is to have the tooth pulled out.  Once the pulp is destroyed, it can’t heal and it is not recommended to leave an infected tooth in the mouth.  Although some prefer an extraction, it is usually best to keep as many natural teeth as possible.
