A painful or sensitive tooth could be the sign of an infection. Left untreated, that infection could cause further discomfort and swelling. Ultimately you may require an extraction to resolve the issue. At High Desert Dental, our dentist, Dr. Ozzie Rodas, can help you keep your smile intact with root canal therapy in Albuquerque, New Mexico. Call High Desert Dental at 505-888-2606 to plan a visit.
