A dental crown is a tooth-shaped "cap" that is placed over a tooth to restore its shape, size, strength, and appearance. Crowns can be made from a variety of materials, including porcelain, metal, and resin. They are typically used to protect a tooth that has been damaged by decay, fracture, or wear. Crowns can also be used to improve the appearance of a tooth that is discolored or misshapen.
Crowns are an important part of restorative dentistry. They can help to prevent further damage to a tooth and can improve its function and appearance. Crowns can also be used to anchor dental bridges and dentures.
