A crown is a technique used in dental restoration when a remaining tooth structure or implant is completely encircled by a “tooth-like” ceramic crown. A crown is recommended for patients who do not have enough healthy tooth structure remaining to support a filling. Crowns are typically made from either ceramic or porcelain material.
If tooth decay becomes severe enough that large portions of a tooth must be removed, crowns are often used to restore both the function and appearance of the decayed tooth. Crowns can be used for purely aesthetic reasons as well when staining and discoloration in teeth become so serve other techniques may not be effective.
