Worn out fillings often lead to further decay and place teeth at high risk for fractures. A crown (or ‘cap’) fits over the remaining part of the tooth, allowing you to keep your tooth. The restoration is strong and provides the cosmetic look of a whole, natural tooth. If you have a missing tooth, replacing it with a bridge is an option. In general, a bridge is a false tooth that is held in place by the teeth on either side of it. Most often, these adjacent teeth will need to have crowns affixed to them.
