Dr. Dahan is a general dentist with a limited practice in TMJ & Sleep Apnea Management. Dr. Dahan was raised in London, Ontario and moved to the Ottawa region after high school. He graduated from Carleton University with a degree in Science and went on to complete a Dental degree at McGill University in 2005. He practiced general dentistry in Ottawa for five years while simultaneously furthering his education with a Masters in Dental Science degree.

His interest in facial pain management and sleep dentistry lead him to leave his dental practice and pursue a clinical fellowship in orofacial pain at the world-renowned Massachusetts General Hospital located in Boston. While there, he was a part-time clinical instructor at Harvard School of Dental Medicine. Following graduation, he moved back to Ottawa to start his private practice and has been awarded a clinical position at the Montreal General Hospital, where his focus is geared to the treatment of facial pain management.

He currently teaches part-time at McGill University and the Montreal General Hospital as a clinical instructor. Dr. Dahan has published three scientific papers supporting his PhD designation and has lectured at Harvard, Tufts and McGill Universities.

Your visit to our office will reflect his genuine and caring nature that is specific to each and every patient’s needs and concerns.

Dr. Dahan is married and has two young boys and a girl. He enjoys spending time outdoors with his family and is currently authoring a book on facial pain management.   

Dr. Dahan and the Ottawa TMJ & Sleep Apnea Clinic were recently chosen as one of the “Companies To Watch” By the Ottawa Business Journal.
