I drink a fair bit of coffee.

While at my dentists yesterday he suggested a procedure called "zoom" for whitening teeth. It costs 700 bucks the first time and then you "freshen it up" every year or so for another 200.

I read the brochure but am a little skeptical. I would hate to lose a layer of enamel just for the sake of cosmetics.

Anyone have any experience with this?
