<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have had braces for two years. For the past year my gums have swelled really bad on top. No one knows why its happening. Very clean teeth. I got my braces tighten recently and the gum between my teeth is being squeezed really bad. What can I do to reduce the swelling?  <response>: Hello, thank you for consulting with Chat Doctor. Actually because of braces there is debris accumulation below the gums. Which a person is unable to clean with normal toothbrush. And this debris causes inflammation of gums because of which they are swelled up. You have to go for oral cleaning with a dentist, as he will do it with specialized machine which will solve the problem. Hope it will help you.
