Summary
A smile is supposed to express one's feelings and expressions, for that there has been an awakening concern for the appearance of gummy smile. Gummy smile is the appearance of about 2mm or more of the gingiva during smiling. It may affect the quality of life of individuals affecting their self-esteem; patients desire to look good not only while resting but while dynamically expressing themselves too. Variable factors contribute to this gingival display whether skeletal, dental or muscular. Variable treatment modalities are done solely or in adjunction to each other for the treatment of gummy smile including both surgical or nonsurgical procedures.
