Review (5/5): The cheapest bleaching system
I first used the CREST WHITESTRIPS when one of my friends had them. The first day I used them I could see that my teeth looked a couple of shades whiter. It has been the best thing on the market as far as a bleaching system. I loved it. I not only noticed the results myself but I also had people complementing me on how white my teeth were. So I had told them about the product and now they are satisfied. The only thing that I have heard bad about them was how sensitive you teeth get after you get done using them but it usually goes away with in the hour or so. They are great!!
