Root Canal: patient guide

Root canal treatment saves a tooth whose pulp is infected or damaged — from deep decay or a crack — by cleaning, disinfecting and sealing the inside of the tooth. It takes 1–2 visits and ends with a permanent filling or crown to protect the tooth. This guide explains each step and how to look after the tooth.
