Opalescence 20%

Product Review (submitted on July 26, 2020):

This product works very well. I've been using it for ~2years and am very happy with it. I use it once weekly for a few weeks before stopping for a period of time. With repeated use it can cause some sensitivity to the teeth and improper placement of the product in the mouthguard can cause gum irritation. Overall, my teeth are absolutely whiter and the price can't be beaten.
