Disappointed + Why are there cosmetic sparkles?

This toothpaste makes a lot of promises but doesn't really follow through. I have not seen any difference in the whiteness of my teeth, and I get a lot of staining from coffee that should be easily dealt with. I don't care that much, it's just toothpaste, but then I saw it contains mica. WHY is MICA (cosmetic sparkles) in a toothpaste? Really unethical, unnecessary, and unhealthy.

Didn't totally love this product.

Although I've had good experiences with other Crest whitening products, this toothpaste just doesn't seem any different than any other toothpaste. It works, in that my mouth feels clean and fresh after using it, but I don't think it whitens noticeably. Especially because of the price difference, I don't think this product is worth it. Also, do not use this product if you have sensitive teeth! I had a friend who used this toothpaste and it was such a painful experience for her.
