If your tooth has severe decay, the nerve can become exposed and infected, and our dentist may need to perform a root canal to restore the health and function of your tooth. Once your root canal is complete, Dr. Greg Cook may place a crown over the treated tooth to protect and strengthen it. For more information on root canals in Alcoa, Tennessee, and to make your appointment at Appalachian Dental, please call us at 865-379-7555 today.
