[This review was collected as part of a promotion.] I was a little hesitant at first as I wasn’t sure if it would cause teeth sensitivity. I have not had any issues and if you use it consistently then you will notice a small difference.

[This review was collected as part of a promotion.] Overall, I’m quite happy with the level of whiteness from pen. After consistent use for a week, I would say that my teeth are at least two shades lighter with minimal sensitivity.
