Dr Scott Overholser DDS on Using Crowns as Protective Coverings no comments
Dr Scott Overholser DDS: Many dental patients in the United States either have had a dental crown placed in their mouth or are in need of one. Many times a crown is used to cover a tooth that has had a very large filling which is breaking down and very little healthy tooth structure remaining. In this way, crowns can be used before a weakened tooth actually fractures, or after this happens. But, being proactive and placing a crown prior to the tooth fracturing can avoid other complications such as a root canal or gum surgery.
Dr Scott Overholser DDS: There are several different kinds of crowns. A full-coverage crown covers the entire tooth, whereas a partial coverage crown is more conservative and covers most of the tooth but leaves certain healthy enamel exposed. Inlays and onlays are usually smaller yet and usually replace older fillings without a need for extensive tooth coverage. Finally, there are several basic types of materials used to make crowns. One of the first materials used in dentistry was gold, which is still used today, but primarily in the most posterior molars where esthetics are not the primary concern. Porcelain-fused-to-metal crowns are often used today in posterior crowns. They have a metal base for strength with porcelain completely covering the outer surface for esthetics. The other type of esthetic crowns used are all-porcelain crowns. Typically, they cover anterior teeth, but can also be used for posterior teeth as well.
