Crown and bridge restorations fall under the category of fixed restorations. Meaning, these types or restorations are cemented permanently into the mouth and are not removed. A crown is used to restore a single tooth to its normal shape and size, allowing it to function normally. A bridge is a restoration that includes multiple units and teeth in order to replace a missing tooth and restore a group of teeth to their normal size and shape. Both crowns and bridges cover or cap the teeth to be restored. This allows us to restore function and aesthetics.
