Root Canal Retreatment

There are cases where a tooth that received root canal treatment may fail to heal or pain may continue to exist. The failure can occur months or years after the initial treatment.

Reasons why treatment may fail

  • Curved or narrow canals that were not treated during the initial treatment.
  • Complicated canals that went undetected during the initial treatment.
  • The crown or restoration was not placed within the appropriate amount of time following the procedure.
  • The crown or restoration that did not prevent saliva from contaminating the inside of the tooth.
  • New decay can expose a root canal filling material, causing infection.
  • A cracked or loose filling or crown can expose the tooth to new infection.
Our endontist has undergone specialist training, so you can rest assured that you will get the best possible results from root canal retreatment.

Once retreatment has been selected as a solution, we will reopen your tooth to gain access to the root canal filling material. This restorative material will be removed to allow access to the root canal. Dr Yoganathan will now clean your canals and carefully examine the inside of the problematic tooth. Once cleaned, the canals will be filled and sealed and a temporary filling placed in the tooth.

At this point, you will need to return to your dentist as soon as possible in order to have a new crown or restoration placed on the tooth to restore full functionality.

Provided you have returned to your dentist in good time, you should now have a healthy, pain free tooth that will last you for many years to come and as it is still your natural tooth, you will have no additional maintenance of this tooth, other than keeping it clean.
