Q. Hi there, I just had a crown fitted (6 upper left!), when the dentist pushed it in I heard a crack!, I thought maybe it broke in half, but he did not say a thing about it. Then he applied some “cement” and my crown has a 45 degree “cemented” line across it??? I believed crown should cover the whole of the tooth. When I went back 3 days (for a filling, on the other side of my mouth) later and questioned him about it he said that it was because of the angle of the crown to fit the remaining tooth. So basically I would like to know if there is such things as “half” crown basically, also the base of that crown is not very “tooth shape”, but he told me that was fine… Could you enlight me regarding this matter. Thank you for your time and consideratin.,
