INTRODUCTION: A gummy smile (GS) affects the esthetic and the psychological status as it usually decreases the self-confidence leading to hidden or controlling the smile. A smile with more than 2 mm exposed gingiva is called gummy smile. It may be due to one or more of the following etiologies; altered passive eruption of teeth, dentoalveolar extrusion, vertical maxillary excess, and short or hyperactive lip muscles. The treatment of gummy smile should be planned according to its cause/causes...

OBJECTIVE: Oral rehabilitation often requires a multidisciplinary approach including restorative dentistry, prosthodontics, and periodontology to fulfill high esthetic and functional demands, frequently combined with changes in the vertical dimension. The presence of gingival recessions can be associated with numerous factors, such as brushing or preparation trauma and persistent inflammation of the gingiva due to inadequate marginal fit of restorations. Because gingival recessions can cause major esthetic and functional problems, obtaining stability of the gingival tissue around prosthetic restorations is of essential concern...

A smile is a mesmerizing expression of joy, success, courtesy and reveals self-confidence. The harmony of the smile is determined not only by the shape, position and the color of teeth, but also by the gingival architecture. Gingival tissues form an important part of what we can consider to be a pleasing smile. The elegance of this pleasant smile could be, affected by highly pigmented gingiva. This gingival pigmentation occurs as a result of melanin granules, which are produced by melanoblast. Although melanin pigmentation does not present a medical problem, demand for cosmetic therapy is commonly sort by people with moderately pigmented gingiva...
