Dental crowns are a type of dental restoration that encases the entire tooth in order to protect it from further damage. Crowns can be made from a variety of materials, including porcelain, ceramic, or metal. In some cases, a combination of these materials may be used.
Crowns are usually placed after a tooth has been damaged by decay or injury. They can also be used to support a dental bridge, cover a dental implant, or enhance the appearance of a misshapen or discoloured tooth.
The specific material used for a crown will be determined by its intended purpose. For example, porcelain crowns are often used for cosmetic purposes, while metal crowns are more durable and frequently used to restore back teeth.
The placement of a dental crown requires two dental visits. During the first appointment, the tooth is prepared and an impression is taken. This impression is then used to create the custom-made crown.
At the second appointment, the crown is placed on the tooth and cemented into place. With proper care, dental crowns can last for many years.
