Hi everyone,
I just realized a couple days ago that I hadn't picked up a 2 week Crest whitening kit for my engagement pic session this Sunday. Has anyone had any luck with the 2 hour version? If so, what brand was it? I know sometimes whitening kits can make your gums tender, but I haven't had a huge problem with that using the Crest 2 week ones. Is it bad with the 2 hour ones?
