Abstract: Exemplary devices and methods facilitate a modular dental device including cartridges. The modular dental device includes an energy storage module, dispensing unit, motor, controller, button, and tube, configured to dispense a compound at a dispensing port. The modular dental device includes a chamber that may receive cartridges containing different compounds, and may serve different functions including cleaning and whitening. The modular dental device may be reconfigured to perform different functions by combining different dental device sections, or by changing the order that different dental device sections are connected in.
