Don't hide those pearly whites!
I saw results after a week. Read the instructions carefully and keep using this item.
I started using this product about a month ago and it works fairly well. It's probably a little harder for me to tell since my teeth are generally fairly white. So overall, it's a good maintainer. It doesn't cause my teeth to be sensitive, which is something I have to worry about with whitening products. It tastes good too.
