Quick little post here. I got a free sample of Crest 3D Whitestripes in the mail a few days ago from Walmart.com. They only sent me two strips, one for my top row of teeth, and one for my bottom row. I’ve never really thought that a little strip of plastic could really whiten your teeth, so I would have never purchased these for myself. Thinking that they don’t work I went ahead and tried them anyway. Directions were simple, peel, place, and forget. The strips weren’t extraordinarily comfortable but they weren’t unbearable. The directions say to have them on for 30 minutes so that’s what I did, and to my surprise after the 30 minutes, my teeth were really a brighter shade of white! Now I’ve never had really yellow teeth, but this is definitely an improvement, and it was only after one use! 

I know this blog post sounds a lot like a commercial for Crest, but I would have to strongly recommend these for anyone who wants to whiten their teeth. They’re slightly pricey though at $43.97, but if a whiter smile is what you want then I would have to say these are worth it.
