Definition of Crowns and Bridges Crowns and bridges are common restorations in modern dentistry.A crown is an artificial restoration that covers a damaged or missing tooth and is intended to restore the tooth's appearance and function.A dental bridge is also a form of restoration that replaces one or more missing teeth by attaching to adjacent healthy teeth or implants to secure the bridge.

　　Difference Between Crown and Bridge

　　There are some distinct differences between crowns and bridges in what they are used for,when they fit,and how they are performed.Here is a detailed comparison between them:

　　1.Purpose

　　Dental crowns are primarily used to restore the shape,function and appearance of a single damaged tooth.It can cover the outer surface of the tooth,including the visible part of the tooth and the part below the crown.While a bridge is used to replace one or more missing teeth,it involves the restoration of multiple teeth.

　　2.Structure

　　A crown is usually a separate free-standing structure that covers a tooth.It can be fixed by dentin or implants.In contrast,a dental bridge is made up of multiple crowns,at least one of which is an artificial crown to replace a missing tooth and the rest to be secured to healthy teeth.

　　3.Operation method

　　Fitting a crown involves grinding part of the damaged tooth so that the crown can fit tightly and restore function.The dentist will make a model of the tooth,and a dental technician will make a crown from the model.In contrast,installing a bridge requires molaring adjacent healthy teeth in order to secure the support of the bridge.

　　Crowns and bridges are two common types of dental restorations.Crowns are used to restore a single damaged tooth,while bridges are used to restore multiple missing teeth.A crown is a single structure while a bridge consists of multiple crowns.Installing a crown requires grinding and making a model,while installing a bridge requires grinding adjacent healthy teeth in order to secure the bridge.According to different tooth conditions and individual needs,the dentist will give appropriate restoration suggestions.
