Abstract: A toothbrush has a shank portion with the brush head carried at one end thereof and a handle at the other end. The shank has a passageway which communicates a paste-holding cavity in the handle to a plurality of bristles mounted on the head end of the toothbrush. The paste-holding cavity of the handle mounts a piston which is axially movable within the paste-holding cavity of the handle in response to a rotatable threaded member so as to compress the paste within the cavity and force the same through the passageway for communication with the bristles. The head has a valve means movable between a first position closing off communication between the passageway and the bristles and a second position permitting such communication.
