Dental crowns are used to cover a tooth that might be likely to break or is too damaged and decayed to be fixed with a filling. A crown is an aesthetic covering or a tooth-shaped “cap” that is placed over another tooth to provide it stability. Crowns are generally used to improve the strength or appearance of teeth. When a large cavity threatens the ongoing health of a tooth, a crown is a good option. Crowns are also used to restore the shape and size of chipped or damaged teeth. They are typically bonded to the tooth using dental cement. We only recommend dental crowns for children when it is absolutely necessary.
