Dentures are formed having a spring steel frame with a curved base and on one side of which pairs of diverging flanges extend at missing tooth positions. Barbed pins extend through the base at the missing tooth positions, and the frame is encased in a resilient, flexible plastic which is molded and colored to resemble the gums of a wearer. Artificial teeth are impaled on the barbed pins. The denture is a generally horseshoe shaped structure which provides a flexible support for the artificial teeth. The diverging flanges of the frame are resiliently deformed so as to grip the gums of a wearer when the dentures are worn. The upper denture requires no stabilizing structure extending across the roof of the mouth of a wearer.
