Botulinum toxin for gummy smile: treatment regrets
This study looks back at patients who had a gummy smile treated with botulinum toxin (Botox) and checks if they regret their decision after three months. It aims to help doctors and patients understand satisfaction with this cosmetic procedure.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- Your gummy smile (more than 3 mm of gum showing when you smile) is caused by an overactive upper lip, not by jaw or teeth issues.
- You previously received a specific botulinum toxin injection at the Yonsei point (a standard treatment spot).
- You have complete dental records and photos from before treatment and at 3 months after treatment.
- You didn't have any other gum surgery or lip repositioning at the same time.
- You didn't have a nerve or muscle disorder (like Myasthenia Gravis), and you weren't pregnant or breastfeeding during treatment.
