Your Oral Health Your Registered Dental Hygienist Your Care Your CDHO


Your oral health is key to your overall physical health and your registered dental hygienist is your expert for preventive oral health care.

Dental hygienists work in a wide variety of practice settings including in their own practice, or independently within a dental health team.

Is my dental hygienist registered?
Only those persons currently registered with CDHO may use the title “dental hygienist” or any variety or translation of “dental hygienist”, including the initials RDH (Registered Dental Hygienist).

All Registered Dental Hygienists in Ontario carry a certificate of registration wallet card, and you may ask to see it. Or, look under Find a Dental Hygienist (on our main site) to verify registration.

What is self-initiation?
Registered Dental Hygienists may provide oral healthcare in settings other than a dental office. They may choose to have their own office or travel to their client’s place of residence. Dental Hygienists who are authorized by the CDHO to “self initiate” do not require the client to have an order from a dentist.
