Root Canal

Root canal treatment is a dental procedure used to treat infection at the centre of a tooth (the root canal system). It's also known as 'endodontics'.
To treat the infection in the root canal, the bacteria need to be removed. This can be done by either removing the tooth (extraction) or attempting to save it by removing the bacteria from the root canal system.

After the bacteria have been removed, the root canal will be filled and the tooth sealed with a filling or crown. In most cases, the inflamed tissue at the end of the tooth will heal naturally.

Before having root canal treatment, you will usually be given a local anaesthetic. This means the procedure shouldn't be painful, and should be no more unpleasant than having a filling. Root canal treatment is usually successful. In about 9 out of 10 cases, a tooth can survive for up to 10 years after root canal treatment.
The infection 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 .
