Bridges, are a permanent type of restoration. This type of restoration is used for people who still have many remaining natural teeth. A fixed bridge can be made of porcelain or of porcelain-covered metal.
American Dental Association answered
Sometimes called a fixed partial denture, a fixed bridge replaces missing teeth with artificial teeth and literally “bridges” the gap where one or more teeth used to be. Bridges can be made from gold, alloys, porcelain or a combination of these materials and are attached to surrounding teeth for support. Unlike a removable bridge, which you can take out and clean, a fixed bridge can only be removed by a dentist.
Bridges can help restore your smile or improve chewing or speaking.
