The terms “crown” and “cap” describe the same thing. It is like a “helmet” that covers and protects a tooth.
This cover fits over a tooth that has been damaged by decay, fractured, or is aesthetically not pleasing. The tooth is “prepared” by your dentist, and usually requires more than one visit to complete.
A crown can be made of acrylic, metal, porcelain, or porcelain bonded to metal. Porcelain crowns look more like your natural teeth, and therefore are usually used for front teeth, while porcelain bonded to metal is stronger and better for crowns in the back of the mouth. Sometimes all-metal crowns are used for back teeth because of its increased strength.
