Hello Dr. Moore. I recently got porcelain crowns on my front two teeth. I think they look a little big. Can they be shaped now that they are in place? I have always hated my two front teeth because they looked too big and I would preferably like them much smaller. I was hoping that the crowns would have made them look smaller. If they try and shape them now will it dull them and is there any chance of them cracking or breaking? Any advice you can provide will be very helpful and I look forward to your reply. Thank you.
