A one-piece molded bruxism treatment device, which in its upright orientation, includes:
a. an elongated generally flat thin planar flexible strip that has a generally U shape defined by a curved front part and a pair of legs extending rearward from the front part about a central longitudinal axis, each leg having a distal end portion, the front part and the legs having top and bottom edges,
b. two generally planar bite pads oriented generally horizontally, each extending from the distal end portion of one of the legs and extending medially toward the other, each of the bite pads having top and bottom surfaces and adapted to be positioned on one side of the person's jaw between the vertically facing surfaces of a person's upper and lower teeth, and
c. each the bite pads being, at least in part, resiliently deformable when the bite pad is clenched between the person's upper and lower teeth,
d. the device further defining a plurality of apertures extending completely through selected parts of the band and the bite pads.
