I would like to inquire about Botox for gummy smile, where the gums are excessively exposed when smiling.

Hello. I am under immense stress because I suffer from a so-called "gummy smile," where my gums show excessively when I laugh. This causes me to cover my mouth whenever I take photos, making my facial expressions look awkward. Gum surgery is too daunting for me, so I am writing to inquire after hearing from a dermatologist that this can be improved with Botox. I am wondering if injecting Botox into the muscle that causes my upper lip to rise too much when I smile would naturally correct the gummy smile. If I proceed with the procedure, I would appreciate it if you could explain in detail when the effects appear, how long they typically last, and whether there is any risk of side effects such as an awkward appearance when smiling or moving my mouth afterward. I know you are busy, but I would be grateful for a kind response as soon as you review this!
