Root Canal Retreatment in Yonkers, Ny


In rare cases, root canal therapy fails to work as expected. Root canal retreatment involves the removal of the previous crown and packing material, the cleansing of the root canals, and the repacking and re-crowning of the tooth. In short, root canal retreatment is almost identical to the original procedure, aside from the structural removal. The success rate for a root canal retreatment runs at an average around 75%.

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 has 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 cost far more than working with the natural tooth. They also require maintenance and feel less natural than a “real” 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 1-3 visits.

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

  • Cracked crown leaking filling material.
  • 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.

What does root canal retreatment involve?
On the day of the retreatment procedure a local anesthetic will be administered, unless another type of anesthetic has been selected. The affected tooth is isolated with a rubber dam. The dam protects the tooth during treatment from bacteria and saliva. The amount the dentist can do within a single appointment will much depend on the amount of inflammation present, and the complexity of the treatment.
