Crowns are a type of dental treatment that can be used for multiple purposes. They are commonly recommended by prosthodontists to repair teeth that have been broken or severely decayed. This is because crowns can provide additional support and protection to the affected tooth, helping to prevent further damage or decay. In addition to this, crowns can also be used to protect weak teeth from further damage, as well as to improve the appearance of teeth that are misshapen or discolored. Overall, crowns are a versatile and effective dental treatment that can help to restore the health and appearance of damaged teeth.
