The ODA has been Ontario’s primary source for dental information since 1867 and represents over 10,000, or 90 per cent, of dentists in the province.

We also advocate for sustainable access to dental care for all Ontarians by working with health-care professionals, governments, the private sector and the public.

The ODA is a voluntary membership organization. Any questions relating to the licensing and regulation of dentists should be directed to the Royal College of Dental Surgeons of Ontario at
