Root canal re-treatment

As with any dental or medical procedure, occasionally a tooth may not 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; or
• Non -healing of previous pathology.

Successfully treated teeth may encounter new problems that may require treatment. This occurs when:

• New decay exposes the root canal filling material to bacteria causing a new infection in the tooth;
• A loose, cracked or broken crown or filling exposes the tooth to new infection; or
• A tooth sustains a fracture.
