In a few days I'll be done with my first box of Crest Strips, but I had started using them last month, then stopped and resumed again a few days ago. I've seen a difference on my top teeth... the bottom strip doesn't seem to stay on my teeth as well. I've been thinking about trying Crest Night Effects (the paint at night) just because they're on sale now. But I'm afraid that since I'd be painting it on myself that my teeth could come out different shades if not applied evenly.
There's an article in June's Consumers Digest about whitening products. It favored dentist-dispensed take-home bleaching trays or one-hour in-office bleaching-- it said those are "the only procedures that get into the dentin and bleach the teeth." It said that "while over the counter products may remove surface stains and temporarily whiten teeth, 'they never bleach or change the color of teeth, because they never reach the dentin,'" according to a a dentist and consumer advisor for the American Dental Association. Dentin's the layer of the tooth under the enamel that has the most color, according to the article.
I think I'll give my teeth a rest for a while after I finish the box... my parents keep saying my teeth are fine but I want my teeth to be as white as Jessica Simpson's-- have you seen them, they're so white!
