Root canal treatment (also called endodontics) is a dental procedure used to treat infection at the centre of a tooth.
This treatment is only required when it is clear that the soft tissue at the centre of the tooth has been damaged by a bacterial infection caused by decay or injury. Your dentist can check this by taking X-rays of your teeth to highlight any problems.
Root canal treatment is carried out by your dentist over two or more appointments. The aim of the treatment is to remove all infection from the root canal. The root is then cleaned and filled to prevent any further infection. This type of treatment tends to be carried out under local anaesthetic.
