Lumineux Non-Toxic Teeth Whitening Strips are a hydrogen-peroxide-free way to whiten your teeth. If you suffer from tooth and gum sensitivity, Lumineux whitening strips are a gentle, convenient and effective way to whiten your teeth. Read my review after trying the strips for 10 days. Yes, but do not expect your teeth to whiten by more than a few shades. They do not whiten as well as Crest 3D Whitestrips, but they are a gentle whitening option that won’t cause tooth and gum sensitivity. For the most part, the Lumineux Non-Toxic Teeth Whitening Strips also stayed on my teeth. I experienced a little slippage of the strips on my bottom teeth, but the strip was easy to put back in place. As far as the taste, I found the strips to have a mild lemon and sage flavor, which I didn’t mind at all.
