Patients who have many missing teeth or severe deterioration of most teeth, may require a full mouth reconstruction using a combination of restorations, veneers, crowns, bridges, dental implants or partial dentures. The oral cavity is a dynamic environment where changes constantly occur, sometimes quickly but more often slowly over time. Changes can be due to a traumatic accident, periodontal disease, shifting teeth, a lifetime of neglect, a destructive habit such as grinding, or a lifetime of dentistry focusing on one tooth at a time and leaving the mouth resembling a patchwork quilt.
