A Crown is a fixed restoration that generally covers the enamel part of a tooth. It can be used in many different tooth restorative situations. Some common uses for a crown include the restoring of a tooth that has had root canal therapy, a fracture, or a large filling. It also is used to improve a discolored or poorly shaped tooth. Dental implants also are finished with a crown. The use of a crown is a great way to help you maintain the proper function and beauty of your smile.
