Anyone try that neon light that you place in your mouth to whiten your teeth?

If yes, did it work and what was the name of it? Thanks so much.

No, sorry, i don't. I tried looking for what you were talking about. I know what you mean, but all i found were the strips. http://ecx.images-amazon.com/images/I/51… Anyways, i know crest and colgate are good. NEVER buy no-name brands!!
