摘要：
Devices for whitening teeth of a user that include a color sensor that detects color of the teeth or that collects data from light that is reflected from the teeth and that controls a teeth-whitening process using the data (e.g., color or shade of the teeth). The device may include a light source (e.g., cool and/or warm light-source elements) that emits light that is reflected by the teeth or to whiten the teeth. Intensity of light may be controlled, e.g., using a processor, learning algorithm, or pulse width modulation circuit. There may be independently-controlled light sources or multiple sensors that sense color in different areas of the mouth. The light source may be located outside the mouth, a reflector may be located inside the mouth, or both. The device may be controlled wirelessly, using a separate electronic device, or with a gesture sensor (e.g., sensing hand gestures).
