If you're missing one or more teeth, you may notice a difference in chewing and speaking. Bridges can help restore your smile. Sometimes called a fixed partial denture, a 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.
