Licensing
Checking a dentist's licence in Ontario
Dentists in Ontario are licensed by the Royal College of Dental Surgeons of Ontario (RCDSO). Its public register shows whether a dentist is licensed, and whether they are a general dentist or a registered specialist.
- Ontario dentists must say in their advertising whether they are registered as a general dentist or as a specialist, and which specialty.
- Testimonials and claims of superiority are not allowed in Ontario dental advertising, which is why no listing here carries ratings or "best" labels.
