After the infected root canal tissue is removed, the pulp chamber and root canals are cleaned, disinfected, filled and sealed. The aim is to leave the tooth in a stable and functional state so that you can comfortably and confidently use it.

In some cases, we may have to re-treat a tooth that has already had root canal treatment, as it has not settled. Working under rubber dam with an operating microscope, which magnifies and illuminates the operating field, our inhouse endodontists, Dr David Treagus and Dr Steve Bonsor can remove posts and old root fillings, find hidden canals and navigate around complex root shapes to treat the entire root canal system and enable healing.

Our clinicians, working with an operating microscope, are able to remove the old root filling and disinfect and fill the entire root system so that the tooth is no longer painful.
