An oral suction device provides an oral suction screen over the oral cavity of a patient by providing upper and lower suction wings attached to a manifold. The wings are inserted between the upper and lower lips and arches of a patient, respectively, and serve to capture aerosols which would otherwise be ejected from the oral cavity. A tongue/cheek retractor, also in pneumatic communication with the manifold, serves to extract saliva and other products from the oral cavity while also preventing the tongue and cheeks from ingress of the workspace for the dental procedure.
