Crest Whitestrips Dental Whitening formula 56 Strips, 14 Day Treatment Review

It is a good product, kind of expensive for me. You can look for coupons in the Internet. Are very flexible, virtually invisible strips. You need to be worn for 30 minutes twice a day, wich could be a lot for people like me. But it is OK: I am a smoker, and after just one 10-day whitening kit, I could see a big difference. I am not an American, and I feel... weird with my teeth if I do not used this product.
