To be considered beautiful, a smile should have harmony among teeth, gums and lips, when this smile is not common, and has excessive gum exposure, it is considered a gummy smile, which can affect an individual's self-esteem and social relations. The treatment for the gummy smile will be according to its etiology and severity. Botulinum toxin is a widely used tool as a complementary or exclusive method in the correction of the gummy smile, and because it is a less invasive treatment, it is indicated for patients who do not wish to undergo surgery. When performing this treatment on the patient, the dental surgeon should inform about its risks, limitations, durability, and results. The objective of this work is to perform a literature review on the etiology and treatment of the gummy smile, as well as to report on its indications. The methodology used was bibliographic research of scientific articles in databases such as PubMed, SciELO, and Google Scholar. We conclude that the use of botulinum toxin is a safe, effective, fast and conservative procedure. Its correct diagnosis of the cause and adequate selection of the technique are fundamental to its importance in the success of the treatment
