Do you whiten or attempt to whiten your teeth?
If yes, what do you do and does it work?
I am currently trying out Crest Whitestrips PREMIUM. I'm on day 1, application 1. I may be crazy, but my top teeth look whiter already. I had trouble applying the lower strip, and I removed it after only 10 minutes instead of the recommended 30. Now I believe I"m gonna have to put my mouth in a ridiculous position to do the bottom row.
