This is an "Anti-Aging" thread - you might want to check the link below, which will take you to the most recent discussion of "teeth whitening", under "Off-Topics". It discusses a range of approaches but if I recall correctly some UV methods are mentioned. You might want to raise your question again over there. Just a suggestion.has anyone heard of or used U V teeth whitening at a tanning salon. apparently you paint this stuff on your teeth and a small device that holds your mouth open and while you tan your teeth also get whitened!!!
