What is a Root Canal? Why do I need one?

Diagram of tooth | Dentist Barrie ON

A root canal is needed when decay begins to spread past the enamel and dentin layer of the tooth and into the nerve of the tooth. Root canal therapy is a treatment used to repair and save a tooth that has become infected and decayed.

Root Canal Process

Throughout the process of a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned thoroughly and sealed to prevent bacteria from re-entering. Without treatment, the tissue surrounding the tooth will become infected and abscesses may form.
