Does it work? And how much does it hurt? How long does it last?
And experences to share please....

I didn't have much luck with zoom whitening. I've had as much success with at home bleaching treatments, as long as you use them regularly. After the Zoom treatment, your teeth are very sensitive and ache for a few days. It can cost from $500 to $1200, depending on how many teeth are being whitened. If you do it, remember you still have to stay on top of keeping them white, via some at home treatment, because whitened teeth will still stain overtime too.
