seems to be working great
I think this product works pretty well.  I took some before and after pictures and there is some whitening of my teeth.  I did not notice it but I asked my husband and he said he notices a difference. I have only been using the product for a few days so I am very optimistic that I would have a change even I could see by the end of the tube.  I am very glad that I was given the opportunity to try this product at a promotional price in exchange  for an unbiased and honest review.
