love it
I used a toothpaste whitening kit by some brand i forgot the name a few months ago and that did not work for me at all. But now I'm using Crest Whitestrips (i have about 4 days left), and I love how white they've left my teeth. I used to just wear chapstick to not bring attention to my mouth, but now i wear red lipsticks without fear! I love it, and if you're really looking for a whiter smile use this instead of the cheaper not very good products out now.
