Compared 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 used when a tooth is broken or decayed to such an extent that fillings aren't able to repair the problem. The crown is able to provide a protective shell around the damaged or decayed tooth to strengthen it, as well as to improve the appearance of the tooth. They can also help restore a tooth to it's original shape, are used commonly for teeth that have been broken. While crowns come in different materials, the most common crowns 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 involves reshaping the tooth and taking scans to create the crown. Typically a portion of you tooth will have to be removed for the crown to fit properly. We will use a digital scanner to capture the details of the prepared tooth. This scan will be sent to a dental laboratory to be made into a permanent crown. Before sending you home, we will provide you with a custom temporary crown to cover your tooth in between visits.
When you return to you dentist, we will remove the temporary crown and fit the new permanent one. Before cementing the permanent crown in place, we will ensure that it fits comfortably and matches the color of your teeth.
