Toothbrush

A toothbrush having a rigid handle, a head on one end of the handle and a multicellular, resilient, compressible sponge pad fixed on a pad mounting surface of the head, said sponge pad having a configuration of a hexagonal cylinder of which a section perpendicular to the mounting surface of the head is hexagonal elongated along a line parallel to the longitudinal direction of the handle, and upper side-surface parallel to the mounting surface of the hexagonal cylinder, said upper surface having a concavity of relatively large area along the axis of the hexagonal cylinder to form two planar top surfaces on opposite sides of the concavity, the under side-surface of the hexagonal cylinder contacting the pad mounting surface being provided with at least one groove through the pad along the axis of the hexagonal cylinder, and the pad being located on the mounting surface so that one of the longitudinally projecting parts between the top surface and the under side surface of the pad extends beyond the free end of the head.
