A recent British study is making some cosmetic dentists and their patients think twice about the way they approach teeth-bleaching treatments.
According to researchers, whitening treatments that implement UV light cause more harm than good. The team found no evidence to support the idea that UV light improves the performance of the bleaching agent that is applied to teeth. Furthermore, it could damage skin and eyes at least as badly as an afternoon of summer sunbathing, and possibly four times as much.
So, does this mark the beginning of the end for light-based bleaching treatments? Until further studies are conducted to prove these researchers’ claims, availability will likely remain high, but additional precautions may be taken.
