Patient Review by Leslie H

The office atmosphere does not feel like your standard dental office. The staff is very welcoming and helpful with any question I may have had. Dr. Mark made my first root canal as pleasant as one could possibly be. His assistance have all been very welcoming and treated me like I was family. Thank you so much!

Patient Review by Dr. Andrew G

As a referring dentist to Dr. O'banion over the last several years I recently found myself in his chair as a patient. (I needed a root canal on a lower molar due to a cracked tooth). My experience was personable, professional and painless. I will continue to refer my patients and friends to Dr. O'banion now more confidently than ever! Dr. Andrew Gast

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 Capital Endodontics, please visit our root canal surgery page. Call us at Dublin Location Phone Number 614-659-7491 if you have additional questions!
