A dental bridge can help prevent the shifting of your existing teeth, which can lead to further damage and misalignment. It also helps maintain proper jaw position and prevents bone loss in the area of missing teeth, helping to keep your other teeth from becoming loose. A dental bridge may be necessary if you are missing one or more teeth due to periodontal disease, birth defects, injury, or severe tooth decay. A bridge can also help in cases where the patient has an uneven bite or a misaligned jaw joint.
