I keep seeing ads for led teeth whitening kits so - do they work?
My friend used one (maybe more than he should have done, not the type to read the instructions) and his teeth have gotten really sensitive ....
I suggest you forget the do it your self kit and talk to a dentist about getting it done.

Thanks for your replies. Was just looking at it as a cheap option, as I can't afford to go to the dentist! But I hve read a few things now about people getting sensitivity, so I think I'll gve it a miss!
