When it comes to durability, the winner is gold alloy. This might not be good news for you if you wanted a tooth-colored restoration, but don’t worry—today’s ceramic crowns are stronger than ever before! Still, if you need a crown on one of your back teeth and you have a habit of grinding your teeth or clenching your jaw, you might want to consider a gold alloy crown, especially if you’d like to avoid ever having to get it replaced.
