When you have a severely decayed or infected tooth, you may need either a tooth extraction or root canal therapy. Root canal therapy is a safe, effective alternative to a tooth extraction, and can preserve your tooth by addressing and removing the infected tissue and strengthening the tooth. At Total Dental Arts, Dr. Kourosh and his staff provide stress and pain-free root canal therapy in Centreville, VA. We work quickly to identify and diagnose infections and find solutions that preserve your natural teeth.
