RETREATMENTS
Why a retreatment?
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.
-
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.
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.
