This is the Bixdo W60 system I tested as my daily brush—sonic cleaning plus 460nm blue light designed to activate PAP whitening toothpaste while you brush. The whole point is convenience: whitening that runs in the background because you’re already brushing twice a day. In my use, the results were gradual but noticeable, and I didn’t get the sensitivity spike I’ve had with some peroxide-based options.
