A dental crown is a tooth-shaped “cap” that is placed over a tooth to cover the tooth to restore its shape and size, strength, and improve its appearance.
The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies above the gum line.
A dental crown completely covers the tooth above the gum line and protects it. Crowns are made of gold or porcelain or a combination of both.
The combination crown has been the primary material of choice, however the usage of all porcelain crowns are now rapidly on the increase due to stronger porcelains being available. These crowns look much more lifelike.
