Abstract
Abstract A pad for artificial teeth which is disposed between a dental plate (either upper or lower) and the gum of the user to hold the plate in proper secure position without discomfort. Two pads can be used when a complete set of artificial teeth is required. The pad is a thin soft flexible cushion of material which does not irritate mucous tissues and has a plurality of spaced indentations or recesses in each of the two opposite major surfaces. The recesses in one surface are out of alignment with the recesses in the other surface and act as suction cups.
