Crowns or caps are used to repair teeth with extensive damage. The damage can be caused by decay (cavities), fractured fillings, root canals, cracked or fractured teeth. Most often in these cases a dental filling is not enough to provide you with long term success. Generally, the only way to completely restore these teeth is a full coverage crown. Most of the crowns used in this office are made of ceramic materials, which make it look and feel very natural.
