With proper care, teeth that have had root canal treatments can last a lifetime. However sometimes, a tooth that has been endodontically treated doesn't heal properly and can become painful or diseased months or even years after treatment. If your tooth failed to heal or develops new problems, you have a second chance. An additional procedure called endodontic retreatment may be performed to save your tooth.
During endodontic retreatment, the endodontist will reopen your tooth and remove the filling materials that was placed in the root canals during the first procedure. The endodontist then carefully examines the tooth, looking for additional canals or new infection. They will then remove any infection, clean and shape the canals and place new filling materials. The opening is then sealed with a temporary filling. Once the tooth heals, a new crown or other restoration is placed on the tooth to protect it.
