Dr. O’Banion, a respected endodontist with 15 years of specialty experience, leads an expert team at Capital Endodontics with offices in Dublin and Lexington, Ohio. They provide the finest endodontic care possible in a compassionate environment of professionalism and clinical excellence.

Specializing in saving the natural teeth, Dr. O’Banion feels it is important to attend more than the required continuing education courses annually, to continually learn, and to be the best endodontist that he can be. He strives to learn the newest techniques all the while aiming for excellence and perfection.

A Diplomate of the American Board of Endodontics, he remains a member of the American Association of Endodontics, the Illinois Endodontic Association, and the Edgar D. Coolidge Endodontic Study Club. He has also been a tutor for clinical and didactic dental courses.

As for his academic career, Dr. O’Banion graduated Summa Cum Laude from the Southern Illinois University School of Dental Medicine in 1998 where he was valedictorian.

Endodontics is the dental specialty concerned with the study and treatment of the dental pulp. An endodontist is a dentist who specializes in treatment to help save teeth. They deal with problems with the inside of the tooth: the pulp, which is made up of nerves, blood vessels, and other soft tissues. One of the most common procedures these dental professionals perform is root canal treatment, which involves removing the infected pulp of a tooth and sealing it up.

Outside of the office, Dr. O’Banion enjoys bicycle racing, cycling, running, skiing, drawing, painting, traveling, and playing chess. Most of all, he enjoys spending time with his beautiful wife and three children. The couple enjoy watching their children in swim meets and school events.
