The World Health Organization said Tuesday that routine, non-essential dental work should be delayed until COVID-19 transmission rates drop sufficiently, cautioning against procedures that produce aerosol spray from patients' mouths.

The WHO said check-ups, dental cleanings and preventive care could be postponed, as it released guidance for dentists on how to minimise the risk of transmission during the coronavirus pandemic.
