Retreatments

We can’t win ‘em all!

While a tooth that has undergone a root canal can last a lifetime with proper treatment, it is possible for it to heal improperly, becoming infected months or years after treatment. If this happens, retreatment can offer your tooth a second chance. A retreatment is an additional procedure that may be able to lessen dental pain and promote healing.

Complications Leading to Retreatment:

  • Narrow or curved canals were not treated during the initial procedure.
  • Complicated canal anatomy went undetected in the first procedure.
  • The placement of the crown or other restoration was delayed following the endodontic treatment.
  • The restoration did not prevent salivary contamination to the inside of the tooth.
  • New decay can expose the root canal filling material to bacteria, causing a new infection in the tooth.
  • A loose, cracked or broken crown or filling can expose the tooth to new infection.
  • A tooth sustains a fracture.

What to Expect During a Retreatment

During a retreatment, we will reopen your tooth the gain access to the root canal filling material. Then the canals will be cleaned, and the inside of the tooth will be examined to look for any additional canals that may need treatment.


After cleaning the canals, they will be filled and sealed, and a temporary filling will be placed in the tooth. Once healed, a new crown/restoration is placed to protect the tooth.

Are There Alternatives to Retreatment?

If nonsurgical retreatment is not an option, endodontic surgery may be considered. Surgery involves creating an incision to allow access to the root. You can discuss your options with Dr. Kumar and her team during your appointment.
