Endodontic Re-treatment

Endodontic treatment generally has a high success rate. Occasionally a tooth may not heal as expected after initial treatment.

Some of the reasons for persistent infections are:

  • Bacteria that is resistant to treatment
  • Narrow or curved canals were not initially treated.
  • Complicated canal anatomy.
  • The placement of the final restoration was delayed which allowed salivary contamination to the inside of the tooth.

In other cases, a successfully treated tooth may become infected due to:

  • New decay that causes exposure of the root canal filling material to bacteria
  • A loose, cracked or broken filling.
