The best thing you can do for your smile
I bought the Crest Whitestrips when they first came out and I was extremely happy with their results. I admit, they were a little expensive at first (10 bucks more than they cost now), but well worth it. I've tried the other products like Simply White or the Crest Night Strips because they were cheaper, and they cannot even compare. It probably has to do with the direct contact of your saliva with the whitening gel. I'm really disappointed in the other products, even Crest Night Effects. The Crest Whitestrips are your safest and best bet when searching for a better, whiter smile.
