What is Endodontics?

Endodontic Retreatment

Endodontic Retreatment

What is Endodontic Retreatment? The majority of teeth recover with problems after endodontic treatment (typically a root canal). However, there are instances where the tooth may not fully heal or continue to cause discomfort. Pain can sometimes resurface months or even years later.

Even though it might be discouraging to have pain again in the area, endodontic retreatment has an exceptionally high success rate - especially with teeth experiencing recurring pain or ongoing problems.

Causes of Continuing Endodontic Problems

A few reasons there might be continuing pain or problems:

  • Delayed placement of a crown or other restoration following initial endodontic treatment
  • New decay, fracture or periodontal disease impacting a tooth.
  • Damaged restoration (crown or onlay)
  • Curved or narrow canals that the previous dentist did not fully clean during initial treatment
  • Complex canal systems that were difficult to spot and access initially


Retreatment is not drastically different from the initial procedure. While the procedure may sound daunting, many people discover that it is no more uncomfortable than getting a cavity filled.

  • Dr. Foronda will start by numbing the area around your tooth and then creating an opening in the crown if there is one present.
  • Once he can see the inside of your tooth, he'll carefully remove the filling material that sealed off the canals during previous treatment, and then clean out the area as needed.
  • Next, Dr. Foronda will reshape your canals to better accommodate a new filling and thoroughly disinfect them before adding fresh gutta-percha (a biocompatible rubber-like material used in root canal therapy).
  • To complete your retreatment, a temporary filling will be placed in the opening of your tooth.

What to Expect Following Endodontic Retreatment

After treatment, you may experience some mild discomfort or tenderness around the tooth for a few days. This can usually be managed with over-the-counter pain medications and should subside within a week.

Dr. Foronda will likely recommend that you schedule a follow-up appointment to verify that the tooth has healed properly and then discuss next steps, which may include adding a new crown or other restoration.
