Frugal Tooth Whitener

I found this Natural White 5-Minute Tooth Whitener at the local Dollar Tree store. The clerk told me that one customer had come back in and purchased 11 packages of it! As your trusty frugal guinea pig, I had to buy it and try it. It is made in the U.S. and has the standard tooth whitening ingredients. You are supposed to use it 2x per day for five minutes. However, I am lazy, so I use it 1x per day while I am in the shower (~15 minutes). My teeth are fairly white to begin with, but I do believe it is working. I particularly like it because it whitens slightly further back into my mouth than Crest Whitestrips do. When I went back to purchase another package of it for future use, I found that they were nearly sold out, but you may be able to find some at your local store. They were located with the toothpaste.
