Works as described. Doesn't make my teeth sensitive. Great product.

Easy and convenient to use. I can see the difference when I use the pen.

Great product, great price.

[This review was collected as part of a promotion.] My 14 year old decided he was using it. He loved it and we have already bought more. It actually helped whiten his teeth from where he had braces and you could see the little marks.

keeps my smile white

[This review was collected as part of a promotion.] This is a great way to brighten teeth at home! I’ve been looking for a way to get whiter teeth and this worked so well for me! My teeth can be sensitive, but I followed the directions and this didn’t cause any sensitivity at all for me.

[This review was collected as part of a promotion.] I love this product!! I have definitely seen a difference after a few weeks of using the product one a day. It will definitely take time to see true result but i can see my teeth are brighter and less yellow-y. Great product!!

Works pretty well but well

I’m still in the process of using these. So far I’ve not noticed much difference. The product is easy to use. Great price

I tried using this pen several times, but each time my teeth got worse instead of whiter. Not happy at all with this product.
