Two different jobs
What is the difference between a crown and a bridge?
Think of a crown as a helmet for one tooth. Your dentist shapes the damaged tooth slightly, then a cap made from porcelain, ceramic or a metal alloy is cemented over it. The cap takes the biting load, holds a cracked tooth together and restores its shape and colour. Crowns are common after a large filling has failed, after root canal treatment, or when a molar has split along a fracture line.
A bridge is several crowns working as a team. When a tooth is missing, the teeth either side of the space are prepared and crowned, and a false tooth (a pontic) is joined between them, so the whole unit is made and fitted as one piece. It stays in your mouth permanently and is cleaned like your own teeth. If the neighbouring teeth are healthy and you would rather not cut them down, the same bridge can sit on dental implants instead.
So the short answer is this: one damaged tooth usually points to a dental crown, and one or more missing teeth points to a bridge, an implant or a denture.
