Root canal treatment is a routine but highly skilled dental procedure which is needed when the blood supply and nerve supply the tooth (the pulp) have become infected due to decay or injury.
If left untreated, the infection can spread throughout the root system and the tooth and cause a painful abscess as well as unsightly tooth discolouration. The aim of a root canal treatment is to stop pain, prevent the spread of infection and save the affected tooth.
Root canal treatment procedures are relatively comfortable and often painless as the tooth is anaesthetised during treatment. After treatment, the tooth may be sensitive or tender for a few days due to inflammation of the surrounding tissues. This discomfort can be relieved by taking mild analgesics or painkillers available over the counter at the pharmacy.
