  • Patent number: 6932088
    Abstract: A mouthguard (10) has a U-shaped base (11) having an upper surface (16) and a lower surface (18). An inner wall (19) extends upwardly from an inner margin of the base upper surface. An outer wall (21) extends upwardly from an outer margin of the base upper surface. The inner and outer walls defined with the base upper surface a trough adapted to receive a person's upper teeth. The improvement comprises a recess (24) that extends into at least one of the inner wall and base proximate the wearer's front or incisor teeth, and extends between the base upper and lower surfaces. The recess is so positioned, configured and arranged as to enable the wearer to suck fluids from the trough through the recess when the mouthguard is installed such that the mouthguard will fit more closely then if such fluids were present in the trough.
