Bridges (also called fixed partial dentures) are the historic "go-to" treatment for replacing a missing tooth when there is a tooth in front of and behind the missing tooth space. Other treatment options for replacing a single missing tooth is a removable partial denture or a dental implant. My patients will typically choose the bridge over a removable partial denture because it feels more like the tooth since it doesn't move around--you can chew better with it. The downside to the bridge is that I have to often times remove perfectly good tooth structure on the teeth next to the space in order to create the room necessary for the bridge to fit over them. Whereas with the dental implant, I typically don't. In most cases I prefer my patients to have a dental implant instead of the bridge or removable partial denture, but sometimes it makes just as much sense to do the bridge (see my Before & After case). One big challenge with bridges that you have to be ready for is that they require more work to get floss under them to clean the teeth in this area. If that is neglected, then almost always you will develop a cavity under there which I typically have to fix by replacing the entire bridge. It's doable though, and many people have had great success with them.
