Crest White strips are a great way to whiten your teeth safely and with out spending a ton of money. My only complaint was that my teeth were more sensitive when I wore them, but returned to normal within a few days of completing them. I actually only used 5 days, rather than 7, because I was afraid of wearing down the enamel (don't worry, it wont. Completely safe). Even with a shortened time, they worked great, and i still get compliments 5 months later about how white they are. Try 'em out.
*Money saving tip: Crest puts out a ten dollar off coupon fairly often so it is easy to get the strips for around 30 dollars. Happy Whitening!
