Root Canal Treatment
If a tooth suffers from dental decay or injury, the nerve and blood supply inside the tooth (known as the pulp) can become infected. As the pulp becomes infected, this infection spreads through the whole root canal system and leads to the formation of an abscess. An abscess is an infected area full of dead cells and pus and causes a swelling in the tissues around the tooth. The symptoms of an abscess can be the darkening of a tooth, a dull throbbing ache, severe pain and tenderness to bite on the tooth. If root canal treatment is not done then the tooth may need to be extracted.
The process of root canal treatment is the removal of the infected pulp, cleaning of the root canal system and once clean, filling the root canal system with a special root canal filling. This process involves a local anaesthetic and is no more painful that a regular filling.
