Root canal treatment (endodontics) is a dental procedure used to treat infection at the centre of a tooth.
Root canal treatment is not painful and can save a tooth that might otherwise have to be removed completely.
The infection at the centre of a tooth (the root canal) is caused by bacteria that live in the mouth and invade the tooth.
This can happen after:
- tooth decay
- leaky fillings
- damage to teeth as a result of trauma, such as a fall
