The present invention is a device for reducing or minimizing the symptoms and/or effects of bruxism and/or morsicatio buccarum comprising a single-piece main body having an approximately U-shaped cross section that fits over one or more teeth. The body has an upper surface, a lower surface and a descending skirt one on either side of said main body and parallel to one another. Each of the descending skirts has an interior side, an exterior side, an top portion and a bottom portion. The top portion is integral to the side of the main body and is narrower in width then the bottom portion. The device is affixed to the tooth or teeth through the compression force produced by and between the descending skirts.
