It didn't work after 2 months
After I read a lot of good reviews I decided to give it a try. I've been using it for almost two months but the results are not similar to what the product's description says (unfortunately), in fact my teeth color are exactly the same. I don't smoke (at all) or drink coffee/wine often.<br /><br />No any gum sensitivity is caused by this product (I have gum recession).<br /><br />I would like to ask for a full refund but the return window was closed one month ago.
