Root canal therapy (or endodontics) helps to save a tooth from extraction by removing infected or inflamed pulp from its chamber. The pulp is the ‘living’ tissue at the center of the tooth and it is packed with nerves and blood vessels.
This soft pulp can be infected by bacteria, which enters the tooth via holes formed by dental decay, a deep filling or damage to the tooth.
- Tooth-saving – a tooth that may have otherwise had to be removed can be retained
- Prevents further infection – if the source of infection is removed it will stop it spreading to other areas
- Pain relieving – an infected tooth can be particularly painful
- Cost-effective – less expensive than having to replace a lost tooth
