When a tooth has abscessed or broken it will be apparent that the inside of the tooth or the dental pulp needs to be removed. This treatment is called root canal therapy or endodontic therapy.
Under a local anaesthetic the pulp of the tooth is removed and the interior is cleansed and disinfected to prevent any bacterial ingress. Once the pulp chamber is cleaned the tooth can be sealed with a root canal filling and then the tooth restored for function.
It is usual to crown a tooth that has been root treated as they can become weaker and brittle after this treatment.
Root canal treatments can take quite a time so do be prepared for a longer appointment. It is not always possible to root treat every tooth and an Xray will be taken prior to deciding on this type of treatment to check if the tooth is suitable.
