A combined toothbrush and toothpaste dispenser, and a disposable toothpaste cartridge for use therein, comprising a brush having a hollow neck and a base with a non-circular opening adapted to receive a complementary non-circular mouth on a disposable toothpaste cartridge. A split tubular element is adapted to be assembled to the brush base and is rotatable with respect thereto. Ribs on the tubular element are disposed so as to clamp the mouth-remote end of the toothpaste cartridge so that rotation of the tubular elememt with respect to the brush base squeezes toothpaste from the cartridge and through the brush neck to the brush head. A tapering shoulder on the toothpaste cartridge adjacent to the mouth cooperates with a ledge on the split tubular element for preventing sliding removal of the mouth from the brush base opening during use. In one embodiment of the invention, the split tubular element forms the handle of the combined toothbrush and toothpaste dispenser, while in another embodiment the handle is integral with the brush and the split tubular element is slidably telescopically received therewithin.
