A crown is a manmade cover that protects the top of a tooth. It may be used to restore and preserve a decayed, broken or cracked tooth. Crowns can also correct some cosmetic tooth problems, giving you a more aesthetically pleasing smile.
Types of Crowns
A crown is made of gold, other metals or porcelain. It can also be made of resin or porcelain and metal. When choosing a crown, think about how it will look and how long it will last. Talk with your dentist about the type of crown that may be best for you.
Metal Crown – This crown is made of gold or other metals. It is very strong and won’t break. Because this type isn’t tooth-colored, it may not be the best choice for a front tooth.
Tooth-colored Crown – A tooth-colored crown is made of porcelain or reinforced resin. It comes in a range of shades to blend with your other teeth. This type of crown may be more likely to chip than a metal crown.
Combination Crown – Porcelain is fused on top of metal, making this crown appear tooth-colored. The metal at its base makes the crown stronger than a porcelain or resin crown. But it is not as strong as a metal crown.
