Root canal means taking the nerve out from the inside of the tooth. Root canal therapy is the treatemt for the teeth that are severely decayed, infected, or broken. Root canal therapy can maintain your teeth life saving them from extraction. The dentist accesses the pulp chamber inside the tooth and locate the root canals contained in the roots of the tooth.
The infected or damaged nerve is removed and the canals are shaped using special files to smooth the walls and ensure no pulp tissue or infection is left. The canals are then filled with a special artificial material that fills and seals off the root canals.
