Abstract: A tongue scraper formed of a handle having a spoon shaped head at one end. The head has a relatively sharply rounded tip and increases in width from the tip to a mid-portion of the head. The head has substantially flat front and back surfaces. A scraper blade projects from the front surface and extends along the edge of the head from the tip to the mid-portion of the head. A plurality of scraper pins project from the front surface of the head and are arranged in a plurality of rows. The scraper pins have tapered top surfaces to provide them with a scraper edge. A plurality of holes extend through the head and are arranged in a plurality of rows. Each of the holes is of an area which can hold a liquid by capillary action.

Abstract: A holder for an interdental toothcleaner of the type having a substantially rigid but flexible stem and cleaning means on the stem. The holder includes a neck having a tip projection radially therefrom adjacent one end thereof and a slot extending longitudinally therealong from the one end and diametrically opposite the tip. A hole extends through the tip and transversely across the neck to the slot. A cap having a passage therethrough which is open at one end and closed at the other end is on the neck and slidable therealong. The cap has a first slot therethrough which extends from its open end and in which the tip slides. The cap has a second slot therethrough diametrically opposite the first slot. The second slot is closed at both ends with the ends being spaced from the ends of the cap. The stem of a toothcleaner passes through the hole in the tip and projects beyond the groove in the neck and through the second slot in the cap.

Abstract: A device for removal of dental plaque from the furca, cemento-enamel junction, and gingival pockets in between two adjacent teeth, the device having a dental arm with a detachable dental brush having a malleable spine supported substantially perpendicular from the arm, the arm imparting a tiny mechanical vibratory action from a motor driving an eccentrically mounted cylindrical weight through contact of the brush with the furca, junctions and pockets in between the adjacent teeth. The brush having a conical shape defined by a cross section representing an isoceles triangle having an apex angle of approximately 30.degree. wherein the surface of the brush is contourable and the bristles are splayed by the tiny vibratory action into the furca, junctions, and pockets.
