Before I was using this I was always having cavities when I went to the dentist and now after using this for almost half a year I don't have any cavities. YAY It does its job and it doesn't have a bad aftertaste like so many do. I would definitely recommend this. I have used the colgate optic white before but I have to say this is a better mouthwash from colgate because the optic white has a bad after taste so that's why I switched to this and it has a much better taste. You could just feel your mouth being cleaned its awesome. And it keeps my breath fresh. This product is the absolute best and so I recommend buying it to try it for yourself. Another great thing about this product is that it doesn't have that burn of alcohol feeling. Also each week the managers usually send out money savingoupons in the sunday paper each week that will save you money on top of the already great prices!
