<p>A toothbrush with liquid-absorbing sponge structure (70) formed with a thickness diminishing to a pointed head which projects outwardly longitudinally from the bristle (50) whereby the absorbed liquid may be introduced into and along the rows of bristles. The sponge structure (70) carries substantially more liquid than the bristles alone and thereby irrigates the mouth while brushing and particularly upon repeated wetting of the brush.</p> |
