Abstract: The denture with suction attachment is an upper or lower denture plate having a floor with at least one suction cavity formed therein, at least one check valve for sealing the chamber formed by the suction cavity and the user's mouth when the denture is installed therein, and at least one suction passage extending between the valve and one suction cavity. The suction cavity may have one or more cavities extending generally across the span of an upper plate, or along the gum line of a lower plate. The suction cavity or cavities are preferably provided with a peripheral seal of a soft, resilient silicone material, or other suitable seal. A suction pump is also provided for removable attachment to the check valve. A magnetic attachment is preferably provided for securing the end of the interconnecting suction pump line to the check valve of the denture.
