Traditional dental restoratives, or fillings, may include gold, porcelain, or composite. Newer dental fillings include ceramic and plastic compounds that mimic the appearance of natural teeth. These compounds, often called composite resins, are typically used on the front teeth where a natural appearance is important. There are two different kinds of fillings: direct and indirect. Direct fillings are fillings placed directly into a prepared cavity in a single visit. Indirect fillings generally require two or more visits. These fillings include inlays, and veneers fabricated with ceramics or composites.
Crowns are a restorative procedure used to improve a tooth’s shape or to strengthen a tooth. Crowns are most often used for teeth that are broken, worn, or have portions destroyed by tooth decay.
A crown is a “cap” cemented onto an existing tooth that usually covers the portion of the tooth above the gum line. In effect, the crown becomes the tooth’s new outer surface. Crowns can be made of porcelain, metal, or both. Porcelain crowns are most often preferred because they mimic the translucency of natural teeth and are very strong.
Crowns or onlays (partial crowns) are needed when there is insufficient tooth strength remaining to hold a filling. Unlike fillings, which apply the restorative material directly into the mouth, a crown is fabricated away from the mouth. A crown is created in a lab from your child's unique tooth impression, which allows a dental laboratory technician to examine all aspects of your child's bite and jaw movements. The crown is then sculpted just for your child so that his or her bite and jaw movements function normally once the crown is placed.
