This may be old hat, but I went to Target on Sunday and found Crest Whitestrips Premium on clearance. I picked them up.
I was not thinking anything spectactular would happen. But, I have to say, 3 days in to this and I am can really see a difference. Verging on a big difference in the color of my teeth.
They're really simple to use, there isn't any nasty taste and the film is tasteless. I just go about doing whatever I do (I'm actually wearing them now) - twice a day for about 30 - 40 minutes and I don't even think about it.
Just wanted to throw it out there if there's anyone on the fence about it!
