Importance of Dental X-rays After Root Canal Treatment

A root canal is the space within the root of a tooth that contains the pulp chamber.  This hollow space houses the nerve, blood vessels, and connective tissue for the tooth.  The pulp of the tooth can become inflamed or infected due to decay or trauma, causing pain and the formation of an abscess.  If an abscess is present, a root canal procedure is done to save or repair the decayed or infected tooth.  During a root canal procedure, the nerve and pulp are removed from inside the tooth and the canal is cleaned and sealed.   

Dental x-rays are recommended during and after root canal treatment.  Periapical x-rays are dental x-rays that take a picture of the whole tooth and root together.  These are suggested at 6 month, 12 month, and 18 month intervals after treatment to evaluate the end of the root tip.  Dental x-rays help to determine if the infection is gone.  You may not be aware of a problem with the tooth because the feeling part (or nerve) of the tooth was removed during the root canal procedure.

Dental x-rays protect your investment after a root canal procedure and monitor the health of the inside of your teeth.
