I had a crown put in that did not fit my mouth. It stuck out the side and hurt the inside of my mouth! He did put a new crown in, however, not only it gave me a crossbite where I did not have one, the color is nothing near the color it should be. Its almost as if they went from one extreme to another. My new dentist has said that the crown was very badly done and has caused decay in the next tooth due to a gap that should have not been there...I also need to replace the crown he has put in.
