I heard the new crown crack while being installed. She gave me another shot and left for a while. She returned and installed the new crown. The crack seems to run across the middle from right to left, in the valley area of the tooth. I can see that the new crown is cracked on the side and that she filled the top of the tooth with some white filler. I am unhappy about this. I don't think she should have replaced an old cracked crown with a new cracked crown.
