This didn't make my teeth any whiter.
I purchased two of these and I have used one. I used it as the instructions told me and it did nothing for my teeth at all. I tried it again and left it on for much longer than the instruction stated and it still did nothing at all. I was very excited about this purchase and couldn't wait to try it but sadly it did not help whiten my teeth at all.
