For the past few years I have been dying to try Crest Whitestrips, and Shoppers Drugmart had them on sale, so I picked up a box of "Advanced Vivid" box. It comes with 14 pouches (each pouch contains one mouth SET). I`ve been using them on and off for the past few weeks. The only difference I`ve been able to notice is how sensitive they make my teeth. I have yet to find them actually whiten them. I will probably not repurchase.
