Crest White Strips Review

Crest white strips are such a great product. Having bought several whitening products in the past that did absolutely nothing, I was dubious about these. So I bought 7 strips off of E-bay for £9.00 to test them out. They're brilliant. I had extremely yellowed teeth due to smoking and drinking coffee, but they are now mostly white with a slight hint of yellow There is a little sensitivity, but I find that it goes not long after removing the strip. However, I've just ordered more as I've seen incredible results from just 1/4 of a full course and would recommend these to anyone.
