Root Canal Therapy:  The living tissue at the center of the tooth can become infected.  This type of dental issue is normally painful, and while antibiotics may alleviate the symptoms, they cannot cure the problem.  The nerve (pulp) tissue must be removed.  This procedure is called root canal therapy.  Dr. Byers utilizes Ozone gas to disinfect the hollowed canal, effectively killing the harmful bacteria.  The canal is filled and sealed, and a cap (crown) will be recommended to provide strength and protection to the weakened tooth.  Root canal therapy can sometimes be performed through an existing crown.  In this case, a restoration (core) will be placed to fill in the access opening.
