Abstract: A toothbrush is provided with a plurality of bristles arranged perpendicular to the working surface of the brush head, and a further plurality of bristles arranged at an angle with respect thereto of preferably 45.degree.. The angled bristles extend from a working platform which is installed on the working surface of the brush head and which provides a further working surface. Such angled bristles promote cleansing of the gingival margin and the gingival sulcus, without requiring the toothbrush head to be canted during brushing. In a highly advantageous embodiment of the invention, further angled bristles are provided extending from a region near the juncture of the working platform and the first working surface of the brush head. In addition, soft perpendicular bristles are arranged to extend from the further working surface.
