Gummy and asymmetric smile was affecting patients’ selfconfidence and life standards. Immediate, nonsurgical botox applications delivered painless and rapid solution to the patients. It has been shown that botulinum toxin type A (BTX-A) injection, which is used in correcting excessive gingival display caused by hyperactive upper lip elevator muscles, is quite effective in gummy and asymmetric smile cases. The patients were reasonably satisfied with the outcomes of the treatment. In spite of the transient effect of BTX-A, even after 6 months of treatment, it was revealed that the gummy and asymmetric smile was within normal limits and did not fully return. For this reason, depending on the needs of the patient, BTX-A injection can be used as an alternative procedure for faster and minimally invasive treatment of gummy and asymmetric smile cases. The purpose of this study is to evaluate the efficacy of conservative treatments like BTX injections in asymmetric and gummy smile cases.
