Abstract: A toothbrush unit allows for storage of a dentifrice within a cavity defined within a toothbrush body. The stored dentifrice is dispensed onto the bristles of the toothbrush head by actuating a bushing drive unit that is also disposed within the body cavity. The bushing drive unit of the toothbrush allows for two-way movement of a compression piston axially along a threaded drivescrew. Upon movement of the piston toward the bristlehead of the toothbrush, in which a plurality of openings are provided, the dentifrice is forced through the cavity, through the bristlehead openings, and onto the bristles. As the supply of the dentifrice is depleted, or at any time refilling is necessary, the piston is moved toward the posterior end of the toothbrush to allow for injection of additional dentifrice into the body cavity.
