What is a root canal?

​

Your teeth have ‘roots’ that anchor them into your jawbone. Inside each of your teeth there is a mixture of blood vessels and nerves called pulp. Pulp sits inside a space called the pulp chamber and this extends down into the roots of the tooth. The pulp chamber within the root is called the root canal.

Why is root canal treatment needed?

​

If your tooth is damaged, bacteria can get inside it. This causes irritation, pain and swelling. If the pulp inside the tooth becomes infected, this can spread into the pulp inside the root canal.

The aim of root canal treatment is to prevent your tooth from being taken out by removing the damaged pulp and treating the infection.

You may need root canal treatment for a number of reasons, including:

• Severe tooth decay

• Repeated dental treatment on the tooth

• A cracked tooth

• A broken crown

• Cracked or loose fillings

• Gum disease

• An injury, such as a blow to your mouth
