She most recently completed an associateship with a private practice in Durham which practiced comprehensive general and family dentistry.

Dr. Bass has experience in all aspects of dentistry including esthetic and functional restorative dentistry, Crown and Bridge including implant restorations, Oral Surgery and Root Canals.  She prides herself on valuing patient education and working with patients to find the most conservative way to restore and maintain their teeth.
