Has anyone had laser teeth whitening at the dentist's office? Is it really more effective than bleaching? I've actually had good luck with at-home whiteners but sometimes I do experience a little sensitivity. I am wondering if laser whitening is better for those with sensitive teeth.

I've had the zoom treatment at the dentist's office. It's a good way to get started, but you still need to keep bleaching at home to maintain it and to keep lightening. I too have sensitive teeth and to tell you the truth I'd rather use GoSmile than go thru that treatment again. Both in terms of effectiveness and comfort.
