In dentistry, a crown refers to the upper part of a tooth protruding from the gingiva.
On the other hand, the term dental crown stands for a type of dental restoration, which completely caps a tooth or implant.
Crowns are often used to restore the health of a tooth that is threatened for example by a large cavity or damaged by accident. Crowns are anchored to the tooth using dental cement and can be made of a variety of materials.
Metal is a common material choice, as well as crowns made of plastic, ceramic or porcelain.
