What does root canal treatment involve?
A root canal is performed when the endodontist removes the infected pulp and nerve in the root of the tooth, cleans and shapes the inside of the root canal, then fills and seals the space. Afterward, your dentist will place a crown on the tooth to protect and restore it to its original function.
Root canal therapy is used to remove nerves from the pulp of a tooth. It is thought to be very painful but is a pain-relieving treatment. The procedure often referred to as root canal is called endodontic therapy.
