Registration

There are over 12,000 registered dental hygienists in Ontario. To practise dental hygiene in Ontario, a person must be registered with the CDHO. Only those persons currently registered with the CDHO may use the title “dental hygienist” or any variety or translation of “dental hygienist”, including the initials RDH (Registered Dental Hygienist).

Registration assures the public that dental hygienists are accountable to the CDHO for providing safe, ethical care that meets the standards of the profession.

Requirements of Registration
The practice of dental hygiene in Ontario is governed under the Regulated Health Professions Act, 1991 (RHPA) and Dental Hygiene Act, 1991 (DHA).

  2. Successfully completed a program of at least two years in dental hygiene that the Registration Committee considers to be equivalent to an accredited program, or
