ABSTRACT:
A uniquely constructed mouthguard designed to minimize discomfort and speech interference associated with conventional mouthpieces includes a pair of posterior portions for encompassing the posterior teeth that are interconnected with a front wall. The front wall overlays a substantial portion of the front surface of the anterior teeth but terminates at a predetermined distance from the lower edge thereof. Accordingly, a wearer's tongue is free to engage the exposed lower edge of the anterior teeth so that the wearer can speak clearly while the device is being worn. Each posterior portion includes an inner and outer wall with the inner wall terminating at the gum line so as to minimize discomfort to the wearer.
