US Patent 10195071 Device and method for the treatment of bruxism

Bruxism, which is a human medical condition characterized by clenching of the jaw and/or grinding of teeth, leads to conditions such as severe tooth wear and Temporomandibular Joint (TMJ) Disorder. Described herein is a biofeedback device that utilizes the human physiological reflex to open the mouth when the nasal airway is obstructed. The device and method blocks the nasal airway while clenching, but allows nasal respiration while not clenching. Clenching of the jaw and breathing through the mouth cannot happen simultaneously while unconscious.
