Abstract: A dental guard including a generally u-shaped band having a curved central portion and a pair of opposite aft ends, each of the aft ends of the band including a laterally extending cylindrical protrusion; and a pair of bite pad assemblies adjustably mountable onto the opposite aft ends of the band. Each of the bite pad assemblies includes a longitudinal channel configured for receiving one of the aft ends of the band for adjusting the location of the bite pad assembly on the band to adjust the length of the dental guard. Each of the bite pad assemblies also includes an elongate slot defined in a sidewall of the bite pad assembly adjacent to and open to the channel, the slot being configured to receive the laterally extending cylindrical protrusion of the aft end of the band and the slot including a plurality of spaced apart receivers for fixedly but releasably receiving the protrusion to enable adjustable positioning of the bite pad assembly relative to the aft end.
