ABSTRACT:
A disposable toothbrush molded from a flexible plastic material and having a brush head carried at one end of a handle. The brush head has a paste-holding cavity and a plurality of hollow bristles molded in and extending from one side of the brush head such that the interiors of the hollow bristles communicate with the paste-holding cavity. A sealing film which functions to maintain the paste within the cavity is punctured upon manual compression of the brush head, such that paste may be squeezed through the hollow bristles to the top end thereof for use. In the second embodiment of the invention the bristle head is disclosed as being separable from the handle.
