Teeth that have had endodontic treatment will last as long as other natural teeth if cared for properly. Occasionally, a tooth that has received treatment may fail to heal or pain may continue to exist, sometimes months or years after initial treatment. When this happens, endodontic retreatment may be needed.
The improper healing of the initial root canal treatment may be a result of: 1) curved or narrow canals that were not treated, 2) complicated canals that went undetected, 3) restoration was not placed soon enough or 4) restoration did not prevent saliva from contaminating the inside of the tooth. New problems, such as decay or a cracked or loose crown, can also expose a root canal filling material and cause a new infection.
Retreatment is much the same as a root canal treatment. At Pla & Watts Endodontics, we will reopen your tooth, and the restorative material will be removed to gain access to the root canal. After indepth cleaning and examination, we will refill and seal the canals and place a temporary filling in the tooth. You will then return to your dentist.
