Abstract

Background: The pursuit of esthetic excellence has become a major goal in the dental treatment. Gummy smile is one of the complaints of the patients, since such a situation can influence self-esteem and social relationships. The beauty of the smile is not only constituted by the shape, position and size of the teeth, but also based on the characteristics of the gingival tissue and conformation of the lips, which should be as harmonious as teeth. The development of new more conservative techniques may provide a better therapeutic option than surgical procedures, such as the application of botulinum toxin, in the treatment of gummy smile. Purpose: to present the case of a patient who presented dentogingival discrepancy caused by gingival overgrowth and gummy smile, treated by gingivoplasty and complemented by application of botulinum toxin.

Results: The gingivoplasty resulted of the improvement of gingival arches and the application of botulinum toxin promoted the dehiscence of upper lip, reducing the gingival exposure. Conclusions: The application of botulinum toxin, associated with gingivoplasty, is an important tool at the management of gummy smile, optimizing smile harmony and achieving improved self-esteem and quality of life.
