Root Canal Retreatment in Irvine & Riverside

Teeth that have received root canal treatment can last as long as other natural teeth given the appropriate care necessary. However, in about 10% of cases a tooth that received treatment may not heal. In these cases, Root Canal Retreatment may be needed.

Improper healing may be caused by:

• Permanent restoration did not prevent penetration of saliva inside the tooth causing contamination.
• A long delay in placing the final restoration after completion of endodontic therapy.
• During initial treatment, complicated root canal anatomy went undetected.
• The canals were not completely cleaned nor disinfected during initial treatment due to narrow or severely curved canals.
• Presence of new or recurrent decay can expose the root canal filling material, causing reinfection.

The process of Root Canal Retreatment is very similar to initial root canal therapy. This treatment is usually done by an Endodontist (root canal specialist). The doctor will have to reopen the affected tooth to gain access to the root canal filling material.

Any restorative material, posts, or obstacles in the pulp space are also removed to allow for successful disinfecting and sealing of the root canal system. 

At the end of the appointment, a temporary filling will be placed inside the tooth and you will need to contact your dentist for placement of a new crown or permanent restoration as soon as possible. A report of your treatment will be send to your referring doctor as well.
