The aim of this study was to evaluate the effect of applying botulinum toxin type A (BTX-A) as a therapeutic alternative for the treatment of gingival smile. Four selected categories of female gender, aged 28–38 years, with gingival smile exposure between 4 and 9 mm, were selected. The evaluation was carried out 15 and 30 days after the initial application. All participants responded to a structured scored interview of initial and final satisfaction. All patients related satisfaction with the final gingival exposure, providing an improvement of their self-esteem. The gingival smile can be treated with botulinum toxin type A as an adjunct to treatments that involve ortho-surgical facial rehabilitation. Although the result is completely reversed after a complete elimination of the product, it can improve the patient’s self-esteem. More clinical trials are important to confirm the results.
