<p>Toothbrushes (10) are provided which incorporate in a handle portion (40) of the toothbrush (10) a volume of a beneficial agent that may be dispensed using an included manual pump mechanism (50). The volume of the beneficial agent provided in the brush and the dispense rate of the beneficial agent may be widely varied. The toothbrush (10) may be constructed to have a beneficial agent volume and dispense rate that are estimated to provide approximately three months of usage to correspond to the length of the effective life of toothbrush bristles (22), thus allowing the entire unit to be disposable upon dispensing of the last of the fluid.</p> |
