(Question) Will my gums become weaker after orthodontic treatment?

I had orthodontic treatment about 30 years ago.

At the time, I was a high school student and didn't pay much attention to my gums, but now that I'm in my late 40s, my gums seem to have weakened.

I don't know if this is because of the braces or my age.

I had 4 teeth removed during braces, 2 on top and 2 on bottom.

It's nice that my teeth are neat, but I'm worried that my gums will get worse as I get older.
