Both crowns and most bridges are fixed prosthetic devices. which you can take out and clean daily, crowns and bridges are cemented onto existing teeth removed by a dentist. Crowns and bridges are a fixed solution to missing or damaged teeth. This restorative procedure uses prosthetic devices to return your smile to its natural state. A crown is used when the tooth structure is damaged or fractured. A bridge is used when one or more teeth are missing.
A crown is used to entirely cover or "cap" a damaged tooth. Besides strengthening a damaged tooth, a crown can be used to improve its appearance, shape or alignment. A crown can also be placed on top of an implant to provide a tooth-like shape and structure for function. Porcelain or ceramic crowns can be matched to the color of your natural teeth. Other materials include gold and metal alloys, acrylic and ceramic. These alloys are generally stronger than porcelain and may be recommended for back teeth. Porcelain bonded to a metal shell is often used because it is both strong and attractive.
