Crowns or “caps” are one of the most common restorations that dentists place. These are covers or “hats” that go over an entire tooth. They are used when there is no other choice and a filling or porcelain veneer will not do the job. They come in various materials, sometimes with a metal coping or thimble covered with porcelain and sometimes without metal, depending on the situation and need for strength and esthetics. Gold crowns are the strongest and most long lasting and are used often in this practice.
