Abstract
A toothbrush with a liquid-storing sponge structure formed with a thickness diminishing to a pointed head which projects outwardly longitudinally from the bristle head. The sponge structure is in contacting engagement with the bristles whereby the stored liquid may be introduced into and along the rows of bristles. The sponge structure carries more liquid than the bristles alone and thereby generates a cleansing foam to the teeth.
