I went to Dr. Morris for the first time with an Amazon Local coupon for the Boost teeth whitening treatment. Dr. Morris seems like a nice guy, and performed the treatment quite well. I have done in-office teeth whitening once before, so knew enough not to expect a miracle with my red wine and coffee assaulted(did I mention old?) teeth. That said, the hour long treatment resulted in a noticeable(if not dramatic) whitening of my teeth — and I consider myself pleased. The process lasted about one hour, was only mildly uncomfortable at the time(bring a smart phone to play with!) and had no after effects beyond a slight sensitivity while brushing for a couple of days. Would this treatment have been worth $ 600(the full retail price)? Well, not to me, but it was a quite reasonable value at a discount. Based on my experience I would be happy to see Dr. Morris for this or other work again.
