Can wearing braces cause gum swelling?
Yes it is normal. Your gums could be irritated from a number of things, not flossing, flossing too hard, just getting your braces tightened. I think it happens to everyone. I have braces right now and certain parts of my gums get swollen, but they go down after a while. But if your gums are swollen, and stay swollen for a long time, then I’d talk to your orthodontist.
