Crest3D White, Whitening Toothpaste Arctic Fresh, 3.0 Ounce

I have to say, this toothpaste is amazing! Why do I say that? BECAUSE the minty feel in your mouth lasts for hours and hours! For example, I brushed my teeth at 10:30 am one day and my mouth STILL felt minty in the late afternoon!! What is IN this stuff? I have NEVER yet come across a toothpaste with capabilities like that. As for whitening, I just used whitening strips, so it's hard to tell how effective this is, but I feel like it probably does something.
