Crowns can also be removed using lower cowhorn forceps..try loosening the crown with a crown remover..if it doesnt come out, engage one beak of cowhorn on the buccal margin of the crown and the other occlusally and the give it a lingual pull..in case of a PFM crown there’s a tendency for the ceramic to chip off when using this technique..if still the crown doesnt come out then it has to be cut and removed..
