UV light-enhanced tooth bleaching is not only a con, but is dangerous to your eyes and skin, says a Royal Society of Chemistry journal.

The light treatment gives absolutely no benefit over bleaching without UV, and damages skin and eyes up to four times as much as sunbathing, reports a study in Photochemical & Photobiological Sciences.

Those looking to match Tom Cruise's glittering pearly-whites would be better off ignoring claims of better bleaching with UV light treatment.

UV whitening doesn’t work? Damn. That means UV vasectomy is off the table too.

My neighbor is a dentist and I remember him saying the same things a few years ago.

Did anyone see the episode where McGee over whitened his teeth? so funny
