Board-certified endodontists have completed the highest level of education in the specialty. Board certification requires a challenging and lengthy process that spans over several years including written, oral, and case history exams. Becoming a Diplomate of the American Board of Endodontics places one in a distinguished group of endodontists who have demonstrated exceptional knowledge and skill, dedication to continued professional growth, and a commitment to providing the highest quality of patient care. Less than 25% of endodontists are Board-Certified.
