Crown and bridge
Crown
A crown is used to restore a very damaged tooth or one that is weakened by cavities, breaks or cracks. It also allows changing the shape, colour, alignment or length of a tooth, which will first be trimmed, as if proceeding with the complete replacement of the enamel layer. The crown is later bonded to the trimmed tooth. A crown can be made of many kinds of materials.
Bridge
A bridge is used to replace one or more missing teeth, to fill the spaces, without the use of a removable partial denture. In fact, a bridge is a series of linked crowns that are bonded onto trimmed teeth.
