The College of Dental Hygienists of Ontario (CDHO) is the regulatory body for over 15,000 Registered Dental Hygienists in Ontario. CDHO is not a school or an organization that advocates on behalf of Registered Dental Hygienists.

CDHO regulates and protects the public by:

• setting the requirements for becoming a Registered Dental Hygienist so that only qualified individuals are allowed to practise and use the title “Registered Dental Hygienist”;
• maintaining an up-to-date feature on its website, known as the public register, to help clients check if their Dental Hygienist is registered and in good standing;
• developing and enforcing standards and guidance for practice;
• running a Quality Assurance Program that helps Registered Dental Hygienists keep their knowledge and skills up to date; and
• receiving and investigating complaints about Registered Dental Hygienists and taking disciplinary action when necessary.

A Council, similar to a board of directors, sets policies and provides leadership and direction to CDHO. A Registrar and staff carry out day-to-day activities.
