                                            Botox is an effective, non-surgical treatment for a gummy smile caused by hyperactive upper lip muscles. Injecting a small amount of botulinum toxin relaxes the muscles that lift the upper lip, causing it to cover more of the gums when smiling. 
How does it work?
A gummy smile, or excessive gingival display, can be caused by various factors, but Botox addresses cases where the upper lip muscles are overactive. 
A practitioner injects Botox into the targeted upper lip muscles, such as the levator labii superioris alaeque nasi (LLSAN) and levator labii superioris. The injection is often at the “Yonsei point,” where these muscles converge.
The Botox temporarily blocks the nerve signals that cause the muscles to contract excessively.
By relaxing these muscles, the upper lip’s movement is limited, preventing it from pulling up too high when you smile. 
What to expect
Procedure: The treatment is quick and minimally invasive, typically taking under 30 minutes. A fine needle is used for the injections, and some practitioners may use a topical numbing cream to maximize comfort.
Results: Patients may begin to see initial improvements within a few days, with the full effect visible around two weeks after the procedure. The result is a more balanced, natural-looking smile with less gum exposure.
Downtime: There is no downtime, and patients can return to their daily activities immediately.
Longevity: The results are temporary, lasting approximately 3 to 6 months. Periodic touch-up treatments are necessary to maintain the effect.
