My teeth whitening experience was wonderful. I'd been wanting to do it for over a year, but had heard so many horror stories about pain and expense that I kept putting it off. Then I heard about affordable teeht whitening with DaVinci and decided, despite my reservations, to take the plunge. It's one of the best things I've done for myself and my career. I'm in sales, and having a bright white smile, and the confidence that comes with it, makes all the difference. And, the best thing - no sensitivity!
