A dental crown is a type of dental restoration that completely covers a damaged or decayed tooth. It is often made from materials like porcelain, metal, or a combination of both, providing strength and improving the tooth's appearance. Crowns are used to restore the shape, size, and function of a tooth, making them an essential option in dentistry. The process of getting a dental crown typically involves two visits to the dentist. During the first visit, the tooth is prepared, and an impression is taken to create a custom crown. A temporary crown may be placed until the permanent one is ready, which is then cemented in place during the second visit.
