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
