Understanding The Benefits of Root Canal Therapy Root canal treatment is necessary when the nerve tissue of the tooth is irreversibly damaged due to decay, trauma, or tooth fracture. It involves repairing and saving the badly infected tooth by removing the pulp and nerves and then protecting it by cleaning and sealing the inside of the tooth. It is conducted under local anaesthesia and the process does not hurt one bit. For more information visit at motivodental.ca. in Public bookmarkswith root-canals
