Dental Crowns

As we age, many of us find ourselves with teeth that are no longer structurally sound. Root canals, lost fillings, decay below a filling, chipping and cracking of the enamel are all things that can lead to large scale defects in a tooth's surface. A dental crown is needed when a tooth is badly broken down - either a cusp has broken off, or there are large old fillings or a large portion of decay. A filling is used to fill a small portion of the tooth - a crown when the tooth has extensive damage. There are basically two types of crowns, those all porcelain/ceramic (metal free) crowns and porcelain fused to metal crowns.
