Abstract: A dental device is provided with a mouth prop for selectively retaining a patient's mouth in an open position while holding the distal end of a suction tube at a desirable location within the patient's mouth for removing fluid and debris. The mouth prop may be provided with a hinge to permit the mouth prop to move between open and compressed positions. The mouth prop may be provided with bump-stops to permit movement of the hinge without crimping the suction tube. Different apertures are provided for coupling the suction tube with the mouth prop., in a variety of positions.
