Can root canal be retreated?

The success rate for a root canal re-treatment is around 70%. Root canal treatments and re-treatments are a better alternative than extraction for most individuals. If a tooth has good bone support, a sound tooth surface and healthy gums beneath, then it stands a good chance of being saved by root canal re-treatment. Retreatment is almost identical to the original procedure except additional removal of root canal filling (gutta percha).
