Root canals are typically necessary in order to avoid an extraction due to extensive decay or following trauma to a tooth. Technological advances in equipment and materials have made root canals less invasive, less painful, faster, and usually completed in one appointment. Root canals are usually done under the same local anesthetic used for fillings but additional options are available for those who have fear or anxiety about dental procedures. During the procedure the canals containing the tooth’s nerve are cleaned out and sterilized. The canals are then filled with a special material to prevent future infections.
Most teeth will require a buildup (permanent filling) and a crown (cap) once the root canal is completed due to a higher risk of fracture. This procedure typically requires no numbing and is completed at a separate appointment.
