I purchased the White Brite teeth whitener unit & ordered the gel pens to go with it: this review is for the gel - however have to mention the little mouth brighter is AMAZING! Works as well as getting 500$ whitening at dentist! 🦷 … The gel is a perfect match for it…I used continuously for one week - saw a 85/90% Highly recommend the mouth whitener & gel pen!
