Review on 🦷 CRI Whitening Toothbrush with Advanced Clinical Technology by Barbara Robinson

This toothbrush is designed to whiten teeth simply by irradiating it with light (no bleach). Put simply, it's impossible. LEDs alone do not make teeth whiter. LED bleaching can definitely work, but only in combination with whitening products. Blue LEDs are only effective when combined with something like hydrogen peroxide. They activate hydrogen peroxide and speed up the bleaching process. But a toothbrush that simply throws LEDs at your teeth while you brush will not help whiten your teeth. I photographed my teeth before and after using this brush and didn't notice any difference. I will also say that the sonic toothbrush performance of this brush is way worse than other much cheaper sonic toothbrushes I've tried. It just doesn't brush as hard or clean my teeth as hard as my other sonic toothbrushes. The LEDs are actually quite bright so I was impressed by that aspect, but then again, blue LEDs can only whiten teeth when combined with peroxide gel. or other bleaching agents. If you really want to try LED whitening, get an LED whitening kit that combines a mouthguard-type LED device with a whitening gel. But this LED toothbrush does not whiten your teeth.
