ABSTRACT:
An improvement to a customizable scuba-diving mouthpiece having a passageway-forming front member extending from a proximal in-mouth end to a distal outside end, and a U-shaped thermoformable back member having a forward middle portion, flanges and bite portions configured to provide moldability at substantially all points of contact between mouthpiece and teeth. The improvement includes the forming of a concave inner and outer surface on the leg portion in order to reduce jaw fatigue, the rearward termination of the inner upstanding flange substantially lateral to the diver's first molar and the tapering of the rear portions of the leg members so as to provide a more comfortable fit.
