Abstract
A mass producible therapeutic device for massaging gingival tissue is disclosed. In the body of the device, oppositely oriented arcuate channels are formed comprising respective recesses generally suited to the conformation of the teeth and adjacent structures. The channels are generally defined by respective pairs of substantially parallel thickened longitudinally extending sidewalls connected through a common interior lateral extension. The body of the device is interiorly slotted or channeled for carrying a fluid, such as air, and the material thereof is sufficiently impermanently deformable so that as a user reciprocably chews into the arcuate channels the effects of fluid redistribution within the body and the elastic character thereof cause the thickened longitudinal sidewalls of the device to flex inwardly against the crowns of the user's teeth for frictionally removing plaque therefrom.
