ABSTRACT:
A toothbrush having an elongated handle, the handle defining a center plane containing the longitudinal axis. A pair of bristle-bearing segments, each segment containing a plurality of bristles mounted therein, is connected to the handle by a pair of short arms. The arms, bristle-bearing segments, and the handle form a fork having two prongs, each prong containing one bristle-bearing segment and one connecting arm. The prongs are located on opposite sides of the first center plane and below a second center plane perpendicular to the first center plane. The bristle-bearing segments have mutually facing inside surfaces sloping toward each other in a gable-manner and intersect above the upper side of the handle at a first angle of less than 55.degree.. The free ends of the bristles bound a gap and define side surfaces sloping in a gable-manner toward each other intersecting above the gap and at a second angle which is less than the first angle.
