A. Hi H, many thanks for your enquiry, this is a very simple problem to rectify. The dentist that has done the work, needs to remove the single crown which is out of place, take a new impression send it to the laboratory which the other crowns were made, he will then place a temporary crown on your tooth. A week later the new crown should arrive and this can be then fitted and all should be good. Hope this is helpful.
