The inside of each tooth contains soft tissue and nerves running from the root to the crown. A crack, deep cavity, or other injury to a tooth can cause the nerve to become damaged and infected. Without treatment, patients can experience pain, swelling and abscesses, tooth loss, and eventually even damage to the surrounding bone. With endodontic treatment, also called root canal therapy, we carefully remove damaged tissue and nerves from the tooth, then gently clean and seal the root canal to protect it from bacteria. It's a completely pain-free procedure and can sometimes be the last remaining option to save the tooth.
