Root Canal Retreatment

Root canal therapy occasionally doesn’t operate as intended. It’s possible that the treated tooth won’t heal correctly or that a patient may have post-operative issues that put the tooth in danger. Root canal retreatment entails removing the old crown and packing material, cleaning the root canals, and then reinstating the packing and crown on the tooth. With the exception of structural removal, root canal retreatment is essentially identical to the first process. A root canal retreatment typically has a success rate of 75%.


For majority of patients, root canal therapies and retreatments are preferable to extractions. A tooth has an excellent chance of being preserved if it has strong bone support, a firm surface, and healthy gums below. The root canal price Toronto retreatment may be significantly lower than the alternatives. Working with the original tooth saves money, while dental implants, elaborate bridgework, and the production of aesthetically acceptable artificial teeth all cost much more. In addition, they need upkeep and don’t feel as natural as “genuine” teeth.

What is the purpose of root canal retreatment?

The idea of more endodontic surgery may not be appealing, but root canal retreatment is a rather straightforward procedure. Typically, the entire course of therapy may be finished in 1-3 visits.


Even teeth that have had root canal therapy can last a lifetime with the right care. However, occasionally a tooth that has had treatment does not heal completely and might develop discomfort or illness months or even years after the procedure. You have a second chance if your tooth doesn’t recover properly or has new issues. Your tooth may be saved and healed with extra treatment. Consult an endodontist about retreatment if a previously treated tooth is causing you pain or discomfort.

Root canal treatment can fail for a variety of reasons, including:

  • A cracked crown is leaking filling material.
  • Curved or narrow canals that were not addressed during the first treatment
  • Delay in placing restorative devices after the surgery.
  • The tooth has developed new decay.
  • A new fracture has formed in the treated tooth.
  • Saliva enters the healing structure.
  • Complex canal constructions that went undetected.
