The practice of "dental hygiene” is defined in the Dental Hygiene Act, 1991, as follows:
“… the assessment of teeth and adjacent tissues and treatment by preventive and therapeutic means and the provision of restorative and orthodontic procedures and services.”
The dental hygiene profession is regulated in the Province of Ontario by the College of Dental Hygienists of Ontario (CDHO), an organization that is responsible for regulating the practice of dental hygiene in the interest of the overall health and safety of the public. To practise dental hygiene in Ontario you must be registered with the CDHO. As such, only CDHO registrants with the appropriate certificate or registration can legally use the term "dental hygienist," or a variation or abbreviation of the term, in this province.
The practice of dental hygiene is regulated under the Regulated Health Professions Act, 1991, and Dental Hygiene Act, 1991. All registered dental hygienists in Ontario must comply with a number of regulations. The CDHO website provides applicants with access to relevant legislative information, registration information, and guidelines related to the practice of dental hygiene in the province.
The CDHO registers dental hygienists for practice only within Ontario. There are three categories of certificates of registration with the CDHO:
- General – This category applies to those dental hygienists who meet the registration requirements and do not hold a specialty.
- Specialty – This applies to registrants who have taken an accredited (or considered substantially equivalent) course of study in restorative dental hygiene.
- Inactive – This is usually held by registrants who are taking some time away from practice; for example, a maternity leave. You cannot practise dental hygiene in Ontario while holding an inactive certificate of registration.
There are approximately 11,994 active registered dental hygienists in Ontario (general and specialty certificates combined). They perform some or all of the following procedures in a variety of health care settings, including private practice, long-term care, public health, education, research and administration:
- implement the dental hygiene process of care which includes conducting an initial dental hygiene assessment, planning treatment, implementing the plan and evaluating the treatment
- consult with other health care providers on patient care
- take dental impressions
- instruct patients regarding oral hygiene procedures and disease prevention
- clean above and below the gums to prevent gum disease
- remove stains and deposits from teeth to prevent tooth and root decay
- apply fluoride and/or other therapeutic treatments
- take and develop X-rays
- may perform restorative and orthodontic procedures in collaboration with a dentist
- may work collaboratively with dental assistants, denturists, dental technicians, and or dentists in their health care functions
In Ontario, dental hygiene is considered a separate and distinct health profession from dentistry. If you are a dentist and are interested in dental hygiene as an alternative, please contact an educational institute which offers an approved program in dental hygiene. There is a listing of approved institutions at the end of this document.
Different countries and regions use different terminology to describe dental hygiene and related occupations. For example, the term “dental therapist” is used in the Canadian provinces of Saskatchewan and Manitoba, and in the territories, to describe someone who may perform many of the same procedures as a dental hygienists but who can also drill and fill cavities. While “dental therapists” and “dental hygienists” may have overlapping skills, they are registered separately in these regions of the country and the titles are not interchangeable.
Dental hygienists work with dentists in a variety of practice settings, for example private practice, long-term care, education, research and administration. They may also work with the military and with public health departments. Dental hygienists work with patients of all ages. Work hours are generally 9:00 a.m. to 5:00 p.m. Evening and Saturday work may be necessary to meet the needs of patients.
Dental hygienists may be employed by one dentist or facility or may work for more than one dentist or facility during their work week. In Ontario, if dental hygienists contract their services to a dentist, they are required to meet self-employment criteria set by the Canada Revenue Agency. In some provinces, dental hygienists are restricted from owning their own business, stand-alone clinic or mobile practice offering service to the public, by a legislative requirement. Dental hygienists in Ontario may own their own businesses. Certain procedures cannot begin without an order from a dentist.

Equivalency Assessment Process
Step 1 — Assessing Academic Qualifications
You must first have the National Dental Hygiene Certification Board (NDHCB) assess your course of study and determine whether or not you are eligible to take its national examination.
If you are eligible to take the national examination you are not required to have your course of study assessed again by the Registration Committee of the CDHO. Contact information for the NDHCB is listed at the end of this document.
If you are not eligible to take the NDHCB examination, you can request that your application be referred to the Registration Committee of the CDHO for consideration.
In this case, you must arrange for your college of graduation to send an original, detailed course description directly to the CDHO. Note that the course description must relate to your years of study.
This course description will include:
- a detailed description of all the subjects taught within your course of study
- the number of hours spent in each subject
- the number of clinical hours actually spent on scaling, root planing and prophylaxis procedures
- how many and what types of clients you were required to perform these procedures on during your course of study
It takes approximately three months for the Registration Committee of the CDHO to assess the course of study and come to a decision once it has received the completed application form and all the required documentation
The assessment fee is $250. If your application is successful, the CDHO will credit this amount towards your initial certificate of registration fee.

- you have already successfully completed the NDHCB written certification examination; or
- your course of study has been approved by the Registration Committee and you have successfully completed the provincial written examination
In accordance to the Dental Hygiene Act, 1991 (Ontario Regulations 218/94 – General – Part I, Examinations), if a candidate fails the examination the following guidelines apply:

- Retake the examination for a fourth attempt if he/she submits to the Registration Committee proof of remediation and upgrading approved by the Committee, and the Committee is satisfied with the documentation submitted by the applicant
- If failing a fourth attempt, the candidate is no longer eligible to retake further examinations
