Argh, my teeth!

I am obsessing about my teeth: They're so brown! I just had them cleaned six months ago, but I'm kind of mad at the hygienist because she didn't scrape all of them. It's like she spot-scraped them or something. I go back in about three weeks. I'm going to ask what she can do to make them whiter. My teeth have always been white; I don't want brown teeth. Grrr. It doesn't help that I drink so much coffee either...or red wine...or dark chocolate...
