Understanding how dental bridges work and who they are recommended to will help you determine whether or not this is the optimal choice for you. Of course, the dentist’s recommendations will also help in the process. Normally, they are used to bridge or close a gap. If you have a missing tooth between two solid teeth, a bridge looks like the ideal option. You practically end up with three crowns that are mixed together. They are cemented and attached to restore your smile and masticating functionality. A bridge can be made from more materials, yet most people choose porcelain over composite materials.
