What to expect from a root canal

A root canal has a worrying reputation it does not really deserve. Here is a plain-language look at what the treatment involves.

Why a root canal is done

When the soft tissue inside a tooth becomes infected or inflamed — often due to deep decay, a crack or injury — a root canal treats the problem from the inside so the natural tooth can be kept rather than removed.

During the treatment

The tooth is numbed with local anaesthesia, so the area is comfortable during the procedure. The dentist cleans the inside of the tooth, shapes the canals and then fills and seals them. Depending on the tooth, this may be completed in one or two visits.

Afterwards

Some mild tenderness for a day or two is normal and usually settles with simple care. A treated tooth can become more brittle, so a protective crown is often advised; your dentist will tell you whether that applies to your tooth.
