ABSTRACT:
The invention is a double sulcus toothbrush having two groups of sulcus bristles which diverge at an angle relative to one another laterally of the toothbrush so that these groups may bear against the upper and lower teeth, inside or out, with the bristles entering the sulci at an angle appropriate for their cleansing, these bristles being optionally forwardly inclined, cut at a taper to facilitate brushing of the rear sulci or separated by a group of conventional bristles which are shorter than the sulcus bristles for brushing the crowns of the teeth.
