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. Bridges are commonly used to cover a space if you’re missing one or more teeth. They are cemented to natural teeth or implants surrounding the space where the tooth once stood. Bridges and crowns can be used to improve a tooth’s appearance, shape, alignment and dental occlusion (bite).
