THAT IT WORKS
I was 65 when I bought this. My teeth weren't dark but I guess you would say mildly stained. It did whiten them noticeably. It can seem a little messy but so is brushing your teeth anyway. My teeth do look whiter and I am happy with the results. When I use I brush my teeth afterwards with my regular toothpaste. Extra brushing is good.
