Abstract: An interproximal dental stimulator and cleaning apparatus having a handle and a flexible member, the flexible member including two wing-like structures which project outwardly from the longitudinal axis of the flexible member, the amount of projection tapering from the base of the member to the tip of the member, so that the member has the general shape of an arrowhead and so that when the member is inserted between adjacent teeth, the wing-like structures conform to the shape of the interproximal gingival papilla, and the structures are thus permitted to occupy the dental sulcus between the papilla and associated teeth.
