The service was excellent, as usual, but as I was having a cracked crown replaced that Dr. Zourdos had installed, I was expecting to get some sort of discount if not an entirely free replacement. I expected this, because I was one of Dr. Zourdos' early patients here in the Milk Street office, and I was wary of the new Cerec systems for making crowns of ceramic blocks, because I was not sure of their longevity. He assured me that these new crowns were great and would last a long time, and that if I ever had a problem, he would take care of it. Well, I had a problem, and the crown cracked for some unknown reason after 7 years. My older crowns never cracked. The front desk said they could not give me any discount, so I was not pleased that this office would not stand behind their products and services as Dr. Zourdos had assured me. Before this incident, I had recommended this office to others. Now I am not so sure.
