οΏ½Endodontic Retreatment
With the appropriate care, your teeth that have had endodontic treatment will last as long as other natural teeth. Yet, a tooth that has received treatment may fail to heal or pain may continue to exist. Sometimes, the pain may occur months or years after treatment. If so, Dr. Cunningham may need to perform Endodontic Retreatment.
Improper healing may be caused by:
- 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.

Inflamed Tissue

Filling Removed

Canals Cleaned

Root Material Placed

Filling Restored

Healed Tooth
In some cases, new problems can influence a tooth that was successfully treated:
- 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.
Once retreatment has been selected as a solution to your problem, the doctors will reopen your tooth to gain access to the root canal filling material. This restorative material will be removed to enable access to the root canal. The doctors will now clean your canals and carefully examine the inside of the problematic tooth. Once cleaned, the doctors will fill and seal the canals and place a temporary filling 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.

Very positive experience for a not so positive reason (I had to redo a 20 year old root canal done elsewhere). The staff was incredibly friendly and informative, they explained everything in great detail once I expressed some interest in knowing what was happening. Dr. Cunningham was excellent as well. He was able to administer the local anesthetic virtually painlessly, and also kept telling me what was happening while making sure I was comfortable. I hope I never have to see the team again, but would return here in an instant for required work. Hard to beat.

I was comfortable in the care of knowledgable professionals. They took time to allow me to ask questions about the upcoming procedure, explained the process very thoroughly, and had given me the cost when I'd made the appointment...so there were no surprises. I knew what to expect. I liked that. And it was obvious I was in the hands of a seasoned, skilled dental professional with a skilled support staff. I HIGHLY recommend Dr. Cunningham.
