Root Canal Treatment 
Root canal treatment (also called endodontics) is needed when the blood or nerve supply of the tooth (known as the pulp) is infected through decay or injury.
In some cases, the tooth could darken in colour which may mean that the nerve of the tooth has died (or is dying). This would need root canal treatment.
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.
Root canal treatment is a skilled and time-consuming procedure. Most courses of treatment will involve two or more visits to your dentist.
