摘要：
Devices for whitening teeth of a user that include a pulse width modulation circuit or a light source and a light delivery mechanism or reflector. The light source may deliver light to the user's teeth and may be located outside the mouth of the user when the device is being used to whiten the teeth of the user while the light delivery mechanism or reflector may be located inside the mouth. The pulse width modulation circuit may drive the light source. The light source may include LEDs or independently-controlled light sources. Intensity of the light source may be controlled, or the device may be controlled wirelessly, for example, using a separate electronic device or hand gestures (e.g., with a gesture sensor). The device may include two antennas or an infrared receiver.
