Abstract: A mouth guard comprises, in one embodiment, a pair of bite pads joined by a connecting portion, each bite pad having an upper bite surface and a lower bite surface, one bite surface being movable relative to the other bite surface to allow relative movement of a user's teeth and jaws to decrease the impact of bruxism and diminish symptoms associated with temporomandibular disorders and the like. In another embodiment, a single wire is formed into a mouth guard comprising a pair of bite pads joined by a connection portion.

Abstract: A method and apparatus are disclosed for exercising small joints such as the temporomandibular joint connecting the upper and lower jaws, fingers and toes of a user. First and second members are coupled together so that at least one of the members is movable relative to the other member. An expandable and contractible fluid reservoir is positioned between the first and second members so that the first and second members will move relative to each other as the expandable and contractible reservoir expands and contracts. At least one of the members is then positioned to exercise the joint specifically to exercise the jaw, the user will place the first and second members gently into the mouth and then squeezing a fluid source connected to the expandable and contractible reservoir to expand and contract said reservoir thereby moving the jaws or joint to be exercised.
