The primary purpose of dental bridges is to replace missing teeth. Patients with one to three consecutive missing teeth are good candidates for bridges. They must also meet the following criteria: Generally in good health Must not have gum disease Both teeth adjacent to the gap must be sufficiently strong and healthy Patients with gum disease should undergo gum disease treatment prior to getting dental bridges. If you prefer an implant-supported bridge, you must also have sufficient jawbone density. Before a dental bridge can be placed, a bone graft procedure could be performed.
