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


Diagram of tooth and roots | Dentist Barrie ONA 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.
