Title: Beauty hurts but it works
Review: Me, my husband and my daughter all used this product. We took before and after pictures. Yes, this products works. I could not use it because I didn't like how it made my teeth so sensitive. My husband is addicted to it. His teeth were always sensitive. He says it only (minor) hurts while it's on then the sensitivity goes away. My daughter said the same. It really took years and years of stains off of his teeth. My teeth were already pretty white so I didn't really see a difference in the few times I used it.
