I have never used that before, but I do love keeping my teeth white, so I have used Crest Night Effects and Aquafresh White Trays, and they both work really really well. Just make sure if you have sensitive teeth, to brush w/ a sensitive toothpaste to make sure your teeth don't get too sensitive....that's what I have to do. Good luck!
