On January 23, 1868, a bill was presented to the new Ontario legislature to regulate the practice of dentistry in Ontario. An Act Respecting Dentistry was passed on March 3, 1868, and full powers of licensing and regulating were placed in the hands of the dental profession.

The Act was the first legislation in the world to grant self-regulation to dentists. Prior to the Act, frauds and imposters with little-to-no medical knowledge and skills advertised themselves as dentists. In the absence of any standards and regulations, the public had no means to distinguish good dentistry from bad, and it put them in danger of injury, infection and even death.

Thanks in large part to the work of one determined Ontarian, Barnabas Day, the ODA addressed an urgent need for trained, educated dental professionals, and took action to help bring Ontario’s dental practices out of the dark ages.

Today, the Ontario Dental Association represents more than 11,000 members, or nine out of 10 dentists in Ontario. Read more about our mission and values.
