Tooth whitening device

The light source may be in the form of an array, powered by either a direct electrical connection to a power supply or by battery power, for example, with a battery pack worn by the user. The light source is thus located in proximity to the tooth surfaces regardless of head movement or orientation, increasing user mobility and comfort.
