Compared to fillings, which just cover a small portion of a tooth, a crown encases the entire visible portion of a tooth, effectively acting as the tooth's new outer surface. A crown is used when a tooth is broken or decayed beyond repair. The crown is able to provide a protective shell around the damaged or decayed tooth to strengthen it and improve its appearance. While crowns come in different materials, the most common ones typically have some mixture of porcelain in them to give them a look and feel similar to a natural tooth.
How it's done
The first visit to Dr. Cozzi involves reshaping the tooth and taking impressions to create the crown. Typically a portion of the tooth will have to be removed in order for the crown to fit properly. After Dr. Cozzi reshapes your tooth, she will create an impression of it, which will be sent to a laboratory so they can make a permanent crown. Dr. Cozzi will provide you with a temporary crown to cover your tooth in between visits.
When you return to you dentist, she will remove the temporary crown and fit the new permanent crown. Before cementing the permanent crown in place, she will ensure that it fits comfortably and matches the color of your teeth.
