ABSTRACT:
Disclosed is a protective, disposable dental patient face mask that covers the patient's entire face, extending partially around the patient's head and secured by a pair of ear bands. A mouth aperture allows access to the patient's mouth and a nose mask that allows the patient to breathe freely while the air is filtered of impurities and flying debris. The face mask is constructed of a material that protects the patient's face from projected liquid and solid materials.
