Frenectomy: Yay or Nay? Would it lift my top lip in the middle, or would it cause me to have a gummy smile? (photos)

I’ve been contemplating whether to get a frenectomy or not. My dentist has mentioned getting it a couple of times however I’ve heard it’s just a way for dentists to get more money out of your pocket. I was wondering whether it would lift my top lip in the middle, or would it cause me to have a gummy smile? My smile is naturally pulled down in the middle of my top lip, is that because of my heavy frenulum or how my smile is?
