A method and apparatus for preventing sleep apnea employs an external clamp that has a first pad that engages the upper lip beneath the nose and a second pad that engages the lower jaw on its underside, behind the mandibular symphysis. The pads are connected to each other by a flexible member, or brace. Preferably the second pad is rounded on that portion that contacts the lower jaw. The clamp is held in place by one or more straps, braces or springs that pass about the patients head. The first pad is held such that it presses against the upper lip while the second pad closes the lower jaw and pulls it forwardly and upwardly using relatively small forces.
