摘要：
Devices for whitening teeth that include at least one sensor that senses whether the device is in the mouth of the user, an electro-magnetic field (EMF) array, or an accelerometer. The sensor(s) or EMF array may enable operation of the device only when the device is in the mouth, turn on the device or a light when placed in the mouth, turn off the device when the device is removed from the mouth, or not allow the device to operate when the device is not in the mouth. A timer may turn off the device. The time may be adjustable, automatically adjusted (e.g., by the device), or adjusted based on color or shade of the teeth. Some embodiments have multiple sensors or EMF arrays or include a wakeup device or accelerometer. The accelerometer may wake up the device when the device is shaken.
