What is root canal therapy used to treat?

ANSWER

Root canal therapy is a treatment used to repair and save a tooth that is badly decayed or infected.

Root canal therapy is performed when the pulp which is composed of nerves and blood vessels in the tooth becomes infected or damaged. During root canal therapy, the pulp is removed, and the inside of the tooth is cleaned and sealed.
