Toronto Dentist at Yonge and Davisville

Dana G. Colson - DDS, FAGD


At Wellness Based Dentistry clients are receiving dental care that preserves more than their teeth. With a strong belief that the mouth indicates the general well-being of the whole body, Dr. Dana Colson, along with her associates, is bringing together leading-edge technology and natural medicine to give clients award-winning smiles that enhance their lives.

In her own words:
Having graduated from Dentistry in 1977 from the University of Toronto, I was fascinated with how the health of the body was reflected in the mouth.
My interest in dentistry stemmed from my fear of dentists. I chose the profession of dentistry because I was determined to overcome my fear of dentistry and help others. The more I learned about the art and science the more my fears diminished. I believe that our clients need to be provided with significant information about their mouth and the various options that are available to them so that we can co-diagnose and co-explore the different opportunities together.
