ABSTRACT:
A respiratory mouthpiece for a toothless person comprising a conduit having an outside open end and an inside open end and adapted to pass untreated atmospheric air from the outside open end to the inside open end. A shield is connected to the conduit adjacent its outside open end to prevent the mouthpiece from being swallowed when the mouthpiece is inserted between the gums of a toothless person. A plurality of perforations in the outer surface of the conduit increase the distribution of inhaled air in the oral cavity. An air filter connected inside the conduit intermediate its open ends purifies the inhaled air from possible pollutants.
