First, a crown is a surgical treatment to improve the appearance and function of a tooth. It is usually used for people with chipped, unevenly colored, and poorly shaped teeth. A crown can cover the surface of a tooth with a layer of artificial tooth to restore the shape and color of the tooth, as well as improve the chewing function and aesthetics of the tooth.
Braces, on the other hand, are a type of orthodontic appliance that is mainly used to straighten teeth. Doctors recommend braces when teeth are misaligned or when the bite needs to be adjusted. Braces move the teeth by applying force to align the teeth and improve the bite. Braces are usually made of materials such as metal, ceramic or plastic, and the appropriate material is selected based on the patient's specific situation and the doctor's recommendation.
In addition, the duration of use differs between crowns and braces. Crowns usually take only a few days or weeks to be fabricated and fitted, while braces take months or longer to gradually move teeth.
In summary, both crowns and braces are tools used to improve dental problems, but they differ in their purpose, application and duration of use. When choosing to use crowns or braces, patients should select the appropriate treatment based on their specific situation and the doctor's recommendation.
