A toothbrush which is adapted to contain a significant quantity of toothpaste therein and to dispense the toothpaste onto the toothbrush bristles. The toothbrush generally comprises a hollow handle having a brush head formed integrally on its top end, a disposable toothpaste containing cartridge supported within its interior, and a piston mechanism threadably attached to its bottom end. The piston mechanism is adapted to force the toothpaste out of the handle into a conduit formed through the brush head. The conduit leads from the interior of the handle to a plurality of outlet holes disposed below resilient valves in a rubber gasket layer which supports the bristles. The valves allow toothpaste to flow from the conduit onto the bristles of the toothpaste while preventing water or other fluids from flowing into the conduit to contaminate the toothpaste supply.
