ABSTRACT:
A toothbrush is provided with a hollow interior cavity adapted to contain liquid dentifrice therein. The toothbrush includes a plurality of minute air apertures for equalizing the air pressure within the cavity and at least one dispensing hole in the bristle region of the toothbrush for dispensing the liquid dentifrice to the bristles. A threaded cap is provided at an open end of a handle of the toothbrush to prevent the dentifrice from escaping from the interior cavity. The cap can be removed to allow the refilling of the interior cavity with the liquid dentifrice.
