An excessive display of gingiva resulting from a high lip line and abnormal gingival overgrowth often complicates treatment planning and can compromise the final esthetic result. Gingival morphology is being considered as an important factor in smile designing. One significant feature of gingival morphology is the gingival line, which is defined as the line joining the tangents of the gingival zeniths of the central incisor and canine. The gingival zenith is the most apical aspect of free gingival margin. With the current emphasis on cosmetic concerns and esthetics in dentistry, lasers are increasingly being used to accomplish esthetic treatment goals.
