Root canal treatment (endodontics)

About the treatment

Inside every tooth is the pulp, the tissue with nerves and blood vessels. When the pulp becomes infected or damaged, through deep decay or an injury, root canal treatment cleans the tooth from the inside and seals it, so the tooth is not lost.

The treatment is done under local anaesthetic, to keep you as comfortable as possible.

Signs you may need it

• Strong or lasting pain
• Long-lasting sensitivity to heat or cold
• Swelling of the gum or face
• A tooth that has changed colour
