A dentifrice-dispensing toothbrush having a handle defining a cavity that is at least partially open at one end of the handle, a dentifrice cartridge located in the cavity and defining an opening located proximate the cavity opening, the opening closed with a cap or temporary seal. There is a head carrying brushing bristles and adapted to be removably engaged with the handle at the cavity opening. The cartridge is fluidly connected to and so delivers dentifrice to the bristles. A roller located in the handle cavity is manually moved to compress the cartridge and so dispense dentifrice; the roller is moved through a roller actuator mechanism coupled to the roller and extending outwardly from the handle.
