A dental crown is used to restore an existing tooth and is cemented into place to cover the entire portion of the tooth that is exposed above the gum line. This "new" tooth surface is usually constructed with porcelain, metal (gold or other metal alloy), or a combination of both. Some people may also refer to crowns as "dental caps" or "tooth caps."
If a tooth needs a crown, it is first recontoured to allow for the crown to fit over it. Then, after an impression is taken, a crown is custom made to fit perfectly around the prepared tooth. While the custom crown is being made, a temporary crown is placed on the tooth to protect it and prevent sensitivity. The crown is then secured in place with a special cement.
Why do teeth need crowns?
There are numerous reasons that a tooth or series of teeth would need to be restored with crowns. Some of these reasons are listed below:
- To restore a tooth's original shape - To support a tooth after root canal therapy - To prevent a tooth from fracturing - To improve the aesthetics of your smile
