Endodontic 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, Endodontic Retreatment may be needed.

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.

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 clean and calming atmosphere. Everything was explained to me prior to my procedure. Very pleasant staff and with exceptional treatment. I was very nervous from my prior visits to another office, I left this office able to return to work as well as keeping my scheduled plans for the evening. I would highly recommend Dr. Erickson to friends, family and co-workers.

I was very pleased with everyone in the office. Dr. Erickson kept me informed as he was moving through the procedures. Checking often to be sure I was doing ok and was very honest about not being able to get all the roots due to a narrow canal. I ended up going back for endodontic surgery a few weeks later. Between the time of the root canal and the endodontic surgery Dr. Erickson checked to see how I was doing and said do not hesitate to call to ask questions or if the pain worsens. I appreciate him calling the day after a procedure to see how you are doing. The experience was not pleasant, but Dr. Erickson and staff made it as pleasant as they could. I would highly recommend this office to anyone needing a root canal or endodontic surgery.
