Crowns are designed to protect a tooth from breaking by covering the tooth on four sides, top, back front and two sides. They are recommended after a tooth breaks, is in danger of breaking, has extensive decay, or has had a root canal, Crowns can be made from metal (precious, semiprecious, non-precious), porcelain fused to metal, porcelain alumina, porcelain zirconia, dilithium silicate porcelain,  plastic or all  feldspathic porcelain. A crown is made by removing tooth structure to compensate for the thickness of the crown. The thicker the crown the more removal of tooth, In this way the crown will be about the same size as the original tooth. Cast metal crowns have been used in dentistry for over 100 years. They do not break and are not abrasive to the opposing teeth. However, they are not esthetic, and therefore, are used in non-visible posterior areas. Delmarva Dental Services only uses precious metal for their all-metal crowns since it is the best. Porcelain are made of different types of porcelains.. The most popular is  porcelain fused to metal crowns.  They are tooth colored with a metal framework under the porcelain for strength. They have been the predominate porcelain crown for over 50 years in the U.S.  Newer metal free frameworks have been developed such as fledspathic, alumina,  zirconium and dilithium silicate.   The most natural looking crowns are E-max (dilithium sulfate).  They are also very strong.  Felspathic and alumina porcelain crowns are weaker and sometimes break especially.  Zirconium porcelain crowns and porcelain fused to metal are stronger and are less likely to break.  Porcelain crowns can wear the opposing teeth and should be highly polished. All plastic crowns are not used much in dentistry because they tend to lose their shine and wear significantly over time and do not offer many advantages over porcelain.Types of Crowns
