I use this product everyday. I have gotten many, many compliments on how amazing my teeth look and I have both Supersmile and my dentist to thank for that. I use this toothpaste as well as whitening kits. The funniest thing is, I had to have a filling done and when my dentist tried to match the filing to my tooth, he was stunned because my teeth were whither than his whitest fillings. I, of course, was proud, although I would have rather not needed a filling. My point here is, this product has definitely worked well for me.
