It's worked on my veneers. I have a weak spot for red wine and noticed that my veneers weren't liking it as much as me. But, this stuff has whitened them up considerably. Also, if you have any sensitivity issues, like I did after veneers, Supersmile really, really helped in that area also. I use the whitening rods with the pastes, maybe that's what helps with the sensitivity, I don't know, but yeah this stuff seems to work.
