ENDODONTICS (ROOT CANALS)
Root canals (endodontics) are required to save the tooth if the pulp, the
living, soft-tissue center of the tooth, is dying. The two main causes of death of the pulp are decay (caries) and injuries. Most root canals are done
by entering the pulp through the chewing surface of the tooth, cleaning out decay as well as dead pulp remnants
and bacteria. The pulp chamber and root canals are filed and irrigated with chemicals to clean and sterilize
them. The canals are then filled with a sterile, inert filling material and a sealer.
Teeth that have received a root canal can be filled, crowned and used as
an attachment for a fixed bridge or removable partial, depending on need. Most textbooks say that the success rate of root canals is about 90%over ten years. I have
completed between 2,500 and 2,700 root canals since I began practice in the
Albuquerque area twenty-three years ago. We know of ten failures in that time.
