Marielle Pariseau, DMD, is a dentist, educator, entrepreneur, and professional speaker whose work reframes oral health as a key to systemic health and prevention. She holds a Doctorate in Dental Medicine from the Université de Montréal, along with advanced certifications in Caries Management by Risk Assessment (University of California, San Francisco), Chronic Disease Prevention (University of Toronto), and Social Entrepreneurship (University of Pennsylvania).

Her TEDx Salt Lake City talk, Teeth: Your Body’s Early Warning System, has reached over one million viewers worldwide and continues to inspire audiences to see teeth with new eyes. Dr. Pariseau has spoken at national and international conferences, engaging healthcare professionals in rethinking the role of dentistry in chronic disease prevention. She was a semi-finalist at Yale University’s Global Health & Innovation Conference and has received recognition as an award-winning speaker.

In addition to her professional practice, Dr. Pariseau has dedicated hundreds of hours to serving underserved populations in Canada, the United States, and Nicaragua. Her work as an inventor, researcher, and change architect reflects a lifelong commitment to bridging dentistry and medicine, challenging silos in healthcare, and advancing prevention at both the clinical and public health levels.

Dr. Pariseau combines her decades of clinical experience, academic training, and public engagement to argue for a paradigm shift: recognizing dental caries as a Sentinel Health Event, a SHE, and using the mouth as a map to better systemic care.
