Dental crowns are fixed dentures made by a dental laboratory that adhere to/on top of the structure of your natural teeth. Crowns are usually needed when teeth are broken and a lot of tooth structure is lost, eg. a broken tooth cavity or filling that is drilled together with a part of the tooth structure.
To get a dental crown, a tooth is made and a matrix is made. The crown is cemented directly into the natural tooth structure. This is done to protect the remaining integrity of the tooth and to extend its life and longevity.

What is the difference between porcelain crown and veneer?
Porcelain veneers are usually applied to the front teeth and resemble artificial nails. Dental laboratories make very thin shards of glass or porcelain that are glued to the front of the teeth.
The teeth under the veneer give strength to the veneer. The veneer itself is not at all strong against the crown, which is the strength that comes from the thickness of the porcelain or metal that underlies the crown.
A crown usually lasts a person's lifetime if it is well placed and the person has good oral hygiene. Insurance companies allow crown replacements every five years, usually longer. The crown usually lasts for several years.
