What can I do if my root canal treatment has failed?

A failed root canal treatment can usually be treated again. Sometimes there are bacteria still present in the tooth that multiply over time and cause a re-infection, or there may be extra canals in your tooth that the dentist could not find at the first treatment. An endodontist (specialist in root canal treatment) is usually the best person to do another treatment. There may be other reasons why your root canal treatment has failed, such as a crack in the tooth. Your dentist or endodontist will be able to work this out, based on X-rays and your symptoms and will advise you on what to do next.
