Root Canal Retreatment

In rare cases, root canal therapy fails to work as expected. The treated tooth might not heal properly or a patient might experience post-surgical complications that jeopardize the tooth. Root canal retreatment involves the removal of the previous root canal filling material, the reshaping and sterilization of the root canals, and the replacement of the root canal filling material. In short, root canal retreatment is almost identical to the original procedure.

Root canal treatments and retreatments are a better alternative than extraction for most individuals. If a tooth has good bone support, a solid surface and healthy gums beneath it, it stands a good chance of being saved. Opting for root canal retreatment can be far less expensive than the alternatives. Dental implants, extensive bridgework and the creation of aesthetically pleasing prosthetic teeth typically cost far more than working with the natural tooth.

Why is root canal retreatment required?

Though the prospect of more endodontic surgery might not be pleasant, root canal retreatment is fairly simple. In general, the whole treatment can be completed in 1 or 2 visits.

There are a number of reasons why root canal therapy unexpectedly fails, including:

  • Undetected cracks that prevent the complete sealing of the treated tooth.
  • Curved or narrow canals not treated during the original procedure.
  • Delay in the placement of restorative devices following the procedure.
  • New decay to the tooth.
  • New fracture in the treated tooth.
  • Saliva entering the restorative structure.
  • Undetected complex canal structures.
