Technologies are generally described for systems, methods and devices relating to sonic toothbrush and whitening compound. In some examples, systems may comprise a sonic toothbrush. The sonic toothbrush may include a head section and a handle section. The head section may include a head at a first end and a connector attached to the handle section at a second end. The head may include bristles, a blue light emitting diode (LED) and a white LED. The handle section may include a sonicator configured to vibrate the head. The handle section may include controls to provide power to the sonicator, to select a speed of the sonicator, to provide power to the blue LED, and to provide power to the white LED. The systems may comprise a whitening compound including hydrogen peroxide. The hydrogen peroxide in the whitening compound may be activated when exposed to light emitted by the blue LED.
