A wireless teeth whitening system includes a mouthpiece that is devoid of any electrical circuitry so that it may easily be cleaned and sterilized. A control module may be coupled to the mouthpiece. This module has an electrical circuit board with LEDs and heating elements mounted on it. When the control module is coupled to the mouthpiece, the system may be used to whiten teeth. The control module includes a battery that may be inductively charged, and may be wirelessly controlled via Bluetooth from a mobile application.
