A dental crown (also referred to as a cap) is a fixed prosthetic object that is cemented onto a tooth. Only a dentist can remove it once it's in place. The main purpose of a crown is to cover a damaged tooth, but it also strengthens it, improving its overall appearance and alignment in the mouth.
Porcelain-fused to metal – This crown provides a stronger bond than regular porcelain because it is connected to a metal structure. It's also extremely durable.
