Abstract
A toothbrush comprises a grip portion and a brush base portion having bristles implanted thereon. The bristles each have a spherical tip. The grip portion has a storage chamber for a fluid material. A communicating passage through which the fluid material may be fed extends from the storage chamber to the bristle-implanted portion so that the fluid material can be fed through the communicating passage. A polishing material may be contained in the tips of the bristles. A medicinal material for oral health or a gingiva-massaging medicine may be contained in the storage chamber.
