The invention claimed is: 1. A bruxism appliance comprising a molded polymeric base for placement and fitting to a patient's upper or lower dentition, the molded polymeric base including an abradable overlayer applied after fitting the molded polymeric base to the upper or lower dentition, the overlayer being a different colour to the polymeric base whereby use of the appliance by the patient indicates the degree of bruxism by the patient by abrasion of the overlayer, wherein the overlayer has a hardness softer that the molded polymeric base, and wherein the overlayer includes an acrylic resin blended with a titanium oxide pigment. 2. A bruxism appliance comprising a molded polymeric base for placement and fitting to a patient's upper or lower dentition, the molded polymeric base including an abradable overlayer applied after fitting the molded polymeric base to the upper or lower dentition, the overlayer being a different colour to the polymeric base and selected from any one of or a combination of acrylic resin, natural resin, or composite, whereby use of the appliance by the patient indicates the degree of bruxism by the patient by abrasion of the overlayer, further comprising a pH indicator bound to the appliance for indicating the pH of a patient's mouth during use of the appliance. 3. A bruxism appliance as in claim 2 wherein the pH indicator is incorporated into the abradable overlayer or is chemically or mechanically fixed to the appliance.
