Sometimes, a tooth that has had Root Canal Treatment may not heal properly and another treatment is needed. The root canal retreatment procedure is similar to the root canal treatment procedure, but has a few extra steps and usually requires two visits. The first visit consists of removal of previous root canal filling materials and placement of an antimicrobial paste such as calcium hydroxide. The tooth is then closed with a temporary filling material. This medicament is left in the tooth for some time to reduce the infection and give the tooth the best chances of healing. On the second visit, the medicated paste is removed, the canals are once again thoroughly cleaned and shaped, and a new root canal filling is placed. Once again, a temporary filling is placed to close the opening in your tooth. Your General Dentist will then restore the tooth.
