A dental crown is a tooth-shaped "cap" placed over a tooth to restore its shape, size, strength, and appearance. Crowns are made from a variety of materials, including porcelain, metal, and ceramic. They can also be used to protect and strengthen a weak tooth, cover a dental implant, or cover a discolored or misshapen tooth.
When a tooth is damaged by decay or injury, dental crowns and bridge treatments can be used to restore the tooth's normal shape and size. The crown completely encases the entire visible portion of the tooth above the gum line. If the tooth is severely decayed or damaged, the dentist may need to do a root canal before placing the crown.

Crowns can also be used to anchor a dental bridge, cover a dental implant, or for cosmetic reasons. If a tooth is severely discolored, a crown can be used to make it look like a natural tooth again. If a tooth is misshapen or has an unusual size or shape, a crown can be used to make it look normal.
Crowns can be made from a variety of materials, including porcelain, metal, and ceramic. The type of material used will depend on the location of the tooth, the amount of wear and tear it will experience, and the patient's preferences. Porcelain crowns are the most popular choice because they look like natural teeth.
