If you're missing one or more teeth, you may notice a difference in chewing and speaking. There are options to help restore your smile. Bridges help maintain the shape of your face as well as alleviating the stress in your bite by replacing missing teeth. Sometimes called a fixed denture, a bridge replaces missing teeth with artificial teeth, looks great and literally bridges the gap where one or more teeth may have been. The restoration can be made from gold alloy, porcelain or a combination of these materials and is bonded onto the 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. An implant bridge attaches artificial teeth directly to the jaw or under the gum line. Depending on which type of bridge your dentist recommends, its success depends on its foundation. So it's very important to keep your remaining teeth healthy and strong.
