ODHA – providing information and sharing helpful resources to assist members.

ODHA is working with the oral health regulators and associations, providing a voice for Ontario dental hygienists. Ultimately, the College of Dental Hygienists of Ontario (CDHO) provides the guidance, expectations and requirements for the profession.  Guidance is posted on the CDHO website. ODHA will continue to assist members and provide new professional development opportunities to keep Ontario dental hygienists informed.

In addition to its guidance on returning to work, CDHO has also released supplemental guidance on the Inclusion of Tele-dental in Dental Hygiene Practices, the extended use of N95 masks/respirators during a supply shortage and isolation gowns.  ODHA encourages dental hygienists to routinely check for updates to the CDHO COVID-19 page.  You can also check for updates to the RCDSO COVID-19 page.

Questions and Answers about COVID‑19
The Canadian Medical Association, along with the Royal College of Physicians and Surgeons of Canada and the College of Family Physicians of Canada has a website to answer your questions about COVID-19.



ODHA continues to participate in the Ministry of Health Emergency Operations Centre’s updates – these updates are weekly.
