Does light-activated bleaching really exist?
Real light activation of bleaching gel can be induced only by incorporating photosensitising agents.
Light activation uses light energy (photons) to accelerate the break-up of hydrogen peroxide into oxygen. The light energy, consumed by the photosensitisers, does not generate heat, preventing tooth dehydration and sensitivity.
Exception is made for some bleaching gels with light activators activated by special and expensive lasers: up to today, no system has been able to light activate a bleaching gel using traditional light sources (multiple wavelengths) and low-power LEDs.
BlancOne® technology for the first time has created real light-activated teeth bleaching using the lights normally used in dental offices, overcoming the concentration-time paradigm of traditional bleaching treatments.
