Crown (tooth)
Crown (tooth)
A Crown (pronounced: /kraʊn/) is a type of Dental restoration that fully caps or encircles a Tooth or Dental implant. Crowns are often needed when a large cavity threatens the ongoing health of a tooth. They are typically bonded to the tooth by Dental cement. Crowns can be made from many materials, which are usually fabricated using Indirect methods. Crowns are often used to improve the strength or appearance of teeth.
Etymology
The term "Crown" comes from the Old French word 'corone', which itself derived from the Latin 'corona', meaning 'garland, crown'. In the context of dentistry, it refers to the top part of a tooth, visible above the gum line.
