I have bad gums. Will contour surgery be okay?

Maybe it's because I had orthodontics when I was young,
 or maybe it's just something I was born with
 , but my gums are
 really bad
. If I eat things like grapefruit, lemons, tangerines, or vitamin drinks, they swell and itch within a few hours at the most, and in
 severe cases, my gums recede and become sore.
 
I receive gum treatment regularly, and my gums are receding. There are a lot of (sinking down) here and there, and
 I removed 4-5 areas that were so bad that they were sore.
 
But I know contour surgery is done by making an incision through the gums,
 but I'm afraid it's okay to have surgery. If I
 do, I think I'll do 2.5 types (cheekbones + square jaw) + Front chin trimming)
 
If it has a negative effect on the gums, it's better not to do it.
 If the gums get worse, I'm really going to have all my teeth pulled out... ㅠㅠ
 
But I don't know if it's okay because there isn't much talk about the gums. I
 went to a hospital and asked, and they said it didn't matter. I can't believe this because this is what the counselor said...;;

If you know someone who has had surgery or know someone well, please respond.
