Root Canal Treatment

A root canal is one of the most common dental procedures with well over 14 million performed every year. This simple treatment can save your natural teeth and prevent the need for dental implants or bridges. For more information on root canal treatment at our Manhattan endodontic office, please visit our treatment page.

Root Canal Surgery

Endodontic (root canal) surgery can be used to locate fractures or hidden canals that do not appear on x-rays but still manifest pain in the tooth. Damaged root surfaces or the surrounding bone may also be treated with this procedure. The most common surgery used to save damaged teeth is an apicoectomy or root-end resection. For more information on root canal surgery at our Manhattan endodontic office, please visit our treatment page.

Always caring for our patients with the highest quality of care and patience
