The Crown and bridge treatment is a long-term method of replacing missing teeth. A crown is placed on an individual tooth (somewhat like a thimble over your finger) when there is no longer sufficient tooth structure to support a filling.
A bridge spans a space where one or more teeth have been lost in the dental arch. The teeth on either end of the span are crowned, and referred to as abutments. The false teeth in the bridge span that joins the abutments are referred to as pontics.
