This work presents an Integrative Literature Review (ILR). Botulinum toxin type A (BTX-A) is widely used in the treatment of gummy smile, characterized by excessive gum exposure when smiling. This literature review analyzed the main advantages, disadvantages, and efficacy of this treatment. BTX-A works by blocking the release of acetylcholine, temporarily inhibiting the contraction of the upper lip elevator muscles, thereby reducing gum exposure. The study reviewed articles published between 2015 and 2024, using databases such as PUBMED and GOOGLE SCHOLAR. The methodology included the selection and analysis of 12 articles that met the established criteria. Studies indicate that this technique is minimally invasive, safe, and offers rapid recovery, providing satisfactory aesthetic results for patients seeking a conservative and less painful solution compared to corrective surgeries, such as gingivectomies or osteotomies. However, its effects are temporary, lasting three to six months, requiring periodic reapplications to maintain results. Additionally, it is essential for the professional to have a deep understanding of facial anatomy and muscle dynamics to avoid complications and asymmetries. In conclusion, although BTX-A is a promising alternative, further studies are needed to assess its limitations, long-term safety, and impact on patients' quality of life.
