How do I get rid of my swollen gums with my braces on?

This is about the 4th straight day that my gums have been swollen, they have swollen all the way down to the brackets of my braces, I've been brushing 2 times daily, using mouthwash 2 times daily, and doing the best I can to floss 2 times daily, but it is only getting worse I've even been gargling my mouth with warm salt water, It can't be the toothpaste because when it started I got new toothpaste and its not helping and I got the mouthwash when it started to swell so its not that either that's causing the swelling. I've tried just about everything and nothing seems to help can someone please help me out?
