In comparison to fillings which just cover a small portion of a tooth, a crown (or cap) encases the entire visible portion of a tooth. In effect, the crown acts as the tooth’s new outer surface. A dental crown is implemented when a tooth is broken or decayed to the extent that fillings cannot repair the problem themselves. The crown offers a protective shell around the damaged or decayed tooth to help strengthen it, as well as to enhance the appearance of the tooth. They can also help restore a tooth to it’s original shape, which are commonly used for teeth that have been broken. While crowns come in different materials, the most common crowns typically have some mixture of porcelain to give them a look and feel similar to a natural tooth.
