LED whitening at home is safe but not as effective as in-office treatment. However, one benefit of the light is that it actually acts as a timer to help keep patients keep the whitening product in contact with the teeth for the right amount of time.
This is because the US, rightly or wrongly, consider all LEDs to be safe! 60825-1 sets accessible emission limits (AELs) for classes, which are used to give an indication of the risk from the beam of the laser or LED. Class 1 is by definition safe, and the majority of LED products fall either into this class or are exempt. LED and laser products are exempt from 60825-1 if the emission level does not exceed the AEL of Class 1 under all conditions of operation, maintenance, service and failure.
