A crown or a “cap” as it is sometimes referred to is a laboratory constructed restoration that is placed when a tooth is too badly broken down to receive a filling. Teeth that have fractured received root canal therapy or are badly decayed often times require a crown.
Crowns are made of many different types of materials from gold to porcelain depending on the functional and esthetic desires of the patient. In addition, crown onlays and inlays are a more conservative way to fix broken down teeth with a less aggressive preparation. They are made of tooth colored porcelain and protect the tooth from fracture. This allows the dentist to conserve more of your tooth structure and still provide a strong long lasting restoration.
