A dental crown, also known as a cap or a covering, is a tooth-shaped shell made of porcelain or metal that covers and protects the entire tooth. A crown can be used to cover and protect an individual tooth (a single-tooth restoration) or several teeth (a multiple-tooth restoration). Crowns are commonly used to protect teeth from damage caused by decay, fractures, cavities, gum disease, and other conditions.
What is the goal?
The goal of this treatment may be to prevent the loss of the natural teeth. The goal might also be to add support for weak or decaying teeth or replace missing teeth due to injury, illness, or extraction. A bridge replaces missing teeth in a row with artificial ones.
