the best whitener
i have tried several different brands, with mixed results. this product does what it claims. after a few applications you really can see a difference. i had absolutely no sensitivity issues when applying the gel. with so many brands on the market, my advice is to stick to this one. it works well, so much so that i receive many comments from people, who are amazed when i tell them i am a smoker and coffee drinker. my wife was so impressed with my results that i have ordered her a kit for her birthday.
