Crown or ‘cap’ is a permanent device that is placed over a tooth to cover it to restore its appearance or to protect it from further damage. It is a hollow tooth like structure placed on a damaged tooth to protect it from breaking or to cover severely distorted or discolored teeth. It can also be used to replace a large filling if not much of the tooth is left or to cover a dental implant or a root canal treatment. The crowns are made of stainless steel or metals such as gold or an alloy or all resin or porcelain fused to metal or all ceramic. A tooth with a crown looks and feels exactly like a natural tooth and requires good oral hygienic practices to prevent wear and tear of the crown.
