Root Canal Retreatment

Whenever possible, it is best to save your natural tooth. Retreated teeth can function well for years, even for a lifetime.

Advances in technology are constantly changing the way root canal treatment is performed, so your endodontist may use new techniques that were not available when you had your first procedure. Your endodontist may be able to resolve your problem with retreatment.

An additional procedure may be able to diminish dental pain or discomfort and promote healing. If you suspect a tooth that had a prior root canal requires retreatment, come see us for evaluation.

As with any dental or medical procedure, it’s possible your tooth won’t heal as expected after initial treatment for a variety of reasons, including:

  • Narrow or curved canals were not treated during the initial procedure.

  • Complicated canal anatomy went undetected in the first procedure.

  • The placement of the crown or other restoration was delayed following the endodontic treatment.

  • The restoration did not prevent salivary contamination to the inside of the tooth.

A new problem can also jeopardize a tooth that was successfully treated, such as:

  • New decay can expose the root canal filling material to bacteria, causing a new infection in the tooth.

  • A loose, cracked or broken crown or filling can expose the tooth to new infection.

  • A tooth sustains a fracture. During retreatment, the endodontist will reopen your tooth and remove the filling materials that were placed in the root canals during the first procedure. The endodontist then carefully examines the tooth, looking for additional canals or new infection. The endodontist then removes any infection, cleans and shapes the canals, and places new filling materials. The opening is then sealed with a temporary filling. Once the tooth heals, which may require more than one visit,  a new crown or other restoration is placed on the tooth to protect it.
