Do Teeth Whitening stripes really work?

You know, those that you can buy at any pharmacy, I've seen them in Wal-Mart too. I was wondering if there's anybody that uses them can you please tell me if they work for you? If so, How much should I expect to pay for them? and What brand is the best? Thanks in advance everyone =D

I would stick with Crest WhiteStrips. They're going to give you the best results. The do work, but not as quickly as or as well as something you could get from your dentist. I believe they are approximately $30-50 when you buy them at Walmart or a pharmacy. Some things to keep in mind: Whitestrips are going to work best on someone who has pretty perfectly straight teeth. Because they are not able to get into the contours between your teeth, you'll see less than desirable results if your teeth are crooked or crowded. Also, don't eat/drink anything that could stain your teeth for approx 24-48 hours after bleaching.
