This toothpaste is quite a bit more expensive than others (for a smaller tube, too!), but when I saw it on special at the supermarket, I thought I'd try it out anyway.
The taste is quite nice - it's a lot mintier than my regular toothpaste, and I felt as though it really cleaned my teeth. I'm not sure about a whitening effect though - I used it for a month, and there wasn't really a noticeable difference.
This toothpaste is ok, nothing great. It created a weird warm feeling in my mouth, and also made my gums start to peel. I think its a good whitening product but takes time to see results, other Colgate whitening toothpastes work just as well and arent that harsh on gums
