Dr. Haissam Dahan
DMD, MSc, PhD. Board-certified in orofacial pain and in dental sleep medicine, clinic owner, educator and best-selling author.

Two decades in dentistry, one focus: the jaw, the airway and the people who suffer when they fail.
Dr. Haissam Dahan’s path in dentistry began at McGill University, where he earned his dental degree in 2005. He went on to complete a Master’s in Dental Education at McGill in 2009 and a PhD in Dental Sciences in 2014, with his doctoral work focused on temporomandibular disorders.
He completed a Clinical Fellowship in Orofacial Pain at the world-renowned Massachusetts General Hospital and is board-certified by both the American Academy of Orofacial Pain and the American Academy of Dental Sleep Medicine. He is also a certified Life Coach with the Optimize Institute, which shapes how he guides dentists through changes in their practice and their careers.
Today he owns and practices at the Ottawa TMJ and Sleep Apnea Clinic, the same clinic Mastery Program dentists visit for their two days of mentorship.

Writing for patients made him a better teacher
Dr. Dahan is the best-selling author of Heal Your TMJ, a self-help guide for people living with TMJ disorders. Explaining a complex condition in plain language to patients is the same skill he now teaches dentists and their teams.
He is also a sought-after speaker at local, regional and international conferences, sharing his approach to TMJ and dental sleep medicine with clinicians around the world.
A husband, a father of three, a marathon finisher, and a traveller with his family.
His interest in health goes well past the dental chair. Dentists who train with him find a mentor with deep expertise, a real commitment to teaching, and a genuine wish to see them thrive.
“Dr. Dahan has taken his lessons as a premier TMJ clinic and is able to share them in a clear and simple way with you and your team through group and one-on-one coaching. He takes a complex topic and makes it easy to follow. Also shows how to grow and maintain a sleep and TMJ practice.”
Ten seats. One year.
A different practice.
Each year Dr. Dahan accepts ten general dentists into the Mastery Program. It starts with a conversation about your practice, your team and where you want your career to go.
