1. An apparatus for sensing the occurrence of bruxism by a human user, said apparatus comprising:

  • a. a plurality of electrically conductive electrodes;

    b. means for holding said plurality of electrodes in contact with the skin in proximity to the temporalis muscles by positive pressure applied by a band extending around the majority of the circumference of said user'"'"'s head;

    c. sense/amplification means for sensing the differential voltage between at least two of said electrodes and selectively amplifying the electrical signals generated by said temporalis muscles, such signals termed "bruxing activity signals";

    d. a detector that generates a bruxing event signal when said bruxing activity signals satisfy predetermined time and amplitude conditions; and

    e. output means for providing a signal external of said detector that corresponds to said bruxing event signal.
