Dental crowns, also known as caps, are custom-made restorations that are designed to cover or replace damaged, decayed, or misshapen teeth. They can be made from a variety of materials, including porcelain, metal, ceramic, or a combination of these materials. Crowns are typically recommended when a tooth is too damaged or weakened to be restored with a filling or bonding, or when a tooth needs to be replaced with a dental implant. The crown is cemented onto the existing tooth structure or implant, providing a strong, durable, and natural-looking restoration. With proper care and maintenance, a dental crown can last for many years.
