Nope
I was unfortunately born with a slight yellow enamel on my teeth, I had high hopes for this product, sadly I was disappointed. I made sure that my teeth were squeaky dry with cotton swabs in both my front upper lip and front bottom lip . I applied the first coat it was a little thin in substance but I thought that it would maybe dry whiter nope it did not I then reapplied a second coat let it dry and yes it was whiter but not noticeably white, I waited for the second coat to dry and applied a third coat yes finally it was much whiter looking however third coat of product got blotchy and didn't spread over teeth evenly and just looked like that I had a lot of horrible plaque build up on the fronts of my teeth. I don't know maybe I didn't wait long enough in-between coats. I do plan on trying this product again. I'll update post on my second attempt.
