Endodontic Retreatment

What are Retreatments?

Root canal retreatment is often necessary if a traditional root canal has failed. In some cases, a root canal isn’t done properly by a dental provider, or there was a canal that was ignored or not treated fully. In this case, you may still experience pain, sensitivity and discomfort to a tooth that has already had a root canal. You will need root canal retreatment to help remove any remaining pulp from the tooth to eliminate this pain.

Why would Retreatments be needed?

Retreatment may be necessary for a variety of reasons. Some reasons are the fault of the dental provider who performed the original root canal and others are completely out of their control. Some reasons you may need retreatment include:

  • You had a hidden canal that went unnoticed on a dental x-ray
  • Your canals are curved or very thin
  • There was a crack that allowed the filling material to leak out of the canals
  • Saliva and bacteria was allowed to get into the tooth during treatment
  • A dental tool or instrument broke off in the tooth during the root canal

Who is a candidate for Retreatment?

Retreatment is often not necessary, since root canals in and of themselves have a high success rate. However, a simple examination and dental x-ray can help us to determine if you may need retreatment. If you require retreatment, it is best to have the procedure done as soon as possible. This helps to prevent further problems from developing, which could result in an infection.

What can you expect with Retreatments?

Retreatment is done similarly to a root canal. The only difference is that the packing material is removed from the tooth before a second root canal is performed. First, we will administer a local anesthetic to numb the area. We then place a dental dam over the tooth to isolate it and prevent bacteria from getting into the tooth while it is open. We then remove the packing material and refill it with new, but similar packing material. The dental dam is removed and you will be ready to go home.
