A message from the Royal College of Dental Surgeons of Ontario:

While the Government has decided that masking requirements will be removed in most places on March 21, this does not include health-care settings.

Dentistry is a health care profession and infection prevention and control requirements, including PPE requirements, are essential to the delivery of safe and effective oral health care. The Ministry of Health continues to require that all patients are screened before being treated. N95 respirators (or equivalent) must be used for any patient interactions involving confirmed, suspected or probable COVID-19 cases, as well as for any aerosol generating procedure (AGP), regardless of screening.
