When a tooth is badly decayed, cracked or damaged, a crown can restore it to its original strength and shape. A crown is a permanent covering that fits over the tooth. They can be made with gold, porcelain fused to gold or entirely of porcelain. Porcelain crowns provide an extremely realistic appearance, and consequently are the most popular type. Crowns can be used to whiten, reshape and realign existing teeth, creating a healthy vibrant smile.
