(Concern) Swollen gums and sensitivity

I had orthodontic treatment a year ago, and now I am living without any problems.

Recently, when I feel tired, I experience tingling and swelling in my gums.

When I get braces, some areas where the teeth move and the roots become slightly exposed feel a bit sensitive.

They said it's an unavoidable part due to the orthodontic treatment.

It's bearable now, and after a while, I felt better.

I'm worried that it might get worse as I age.
