I have to amend an earlier review. I am sorry that, the crown that Dr. Perretta put in so painlessly and excellently, needs some minor adjustments. On the day it was put in I felt uncomfortable and told him and he looked at it and said it's fine. I put up with a too high crown for too long, adjusting to it. Eventually the jaw pain got worse. I asked for an adjustment. He quickly and hurridly shaved a bit off. The problem persists.. I went back and he has argued with me, insisting that the crown is perfect, even though I feel slight pressure on it. After arguing with him, he did some work on the crown to make it slightly wider, and it feel much better but not completely. He refused to do more. I cannot understand this. He is a good dentist but does not care how people feel. My discomfort means nothing--only his opinion of how the crown looks to him. It is disappointing, (the crown is just a bit narrow inside and is pressing on the lower tooth--this is simple stuff and should have been fixed immediately). I must withdraw my recommendation of this peculiar doctor, who is so good and yet so callous towards his patients needs and feelings.I cannot call this experience pain free anymore. Doctors need to have a heart.
