Hi, i got braces about 4 months ago, and everything was fine untill about 2 weeks ago when i went in to get them tightened and a larger wire, btw i had spaces on my top two front teeth but about a week ago i felt my gums because they were hurting especially behind my 2 top teeth and i looked in the mirror and it looks like my gums got squished together or something and they look swollen, i just got scared because i thought it was something bad, and it hurts when i brush behind there, do you think there’s anything i can do to get rid of it ?
