Prior to initiating any esthetic treatment, it is important for the dentist to examine and diagnose the overall esthetic condition of the patient. Performing a smile analysis includes an evaluation of how the teeth are positioned in the face and their relationship to the lips, as well as a tooth-by-tooth analysis and treatment. We will examine the principles of smile analysis, esthetic re-contouring for natural teeth and restorations, and periodontal and orthodontic considerations for maximum esthetics.
