As occasionally happens with any dental or medical procedure, a tooth may not heal as expected after initial treatment for a variety of reasons:

  • Narrow or curved canals were not treated during the initial procedure
  • Complicated canal anatomy went undetected in the first procedure
  • Placement of the crown or other restoration was delayed following the endodontic treatment
  • Restoration did not prevent salivary contamination to the inside of the tooth
  • Failure of the body’s immune system to resolve the infection

In other cases, a new problem can jeopardize a tooth that was successfully treated.

For example:

  • 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
