A dental crown is a type of dental restoration that completely covers or "caps" a damaged or weakened tooth to restore its function, strength, and appearance.

There are different types of dental crowns, including porcelain, ceramic, metal, and a combination of materials. The choice of material depends on the location of the tooth, the amount of stress the tooth will be under, and the aesthetic considerations.

The process of getting a dental crown typically involves several appointments with a dentist. The first appointment involves preparing the tooth for the crown by removing any decay or damage and shaping the tooth to accommodate the crown. An impression of the tooth is then made to create a custom-made crown. A temporary crown may be placed on the tooth until the permanent crown is ready.

During the second appointment, the temporary crown is removed, and the permanent crown is fitted and cemented onto the tooth after making any necessary adjustment.
