Crowns are casings that are cemented on top of damaged teeth. They are durable, long lasting, and shade-matched to look as natural as possible. A bridge is used to fill a gap where there is no teeth. A bridge contains two components – the pontic teeth occupy the gap, while the two teeth on either end are used to anchor the bridge. Both bridges and crowns are prepared in a dental lab using a custom impression taken from you. They can be made of a variety of materials, such as porcelain, gold, and metal alloys, and the chosen material is based on patient preference, function, and esthetics.
