I'm having an issue with the gum above one of my braced teeth. Just in the last few days it has been bleeding a hell of a lot when I brush and it is really sore, when I look at it it looks more red than the rest of my gum and it looks like it is covering more of my tooth, if that is even possible. When I use my little in between brush thingy (sorry I don't know proper terms) it is hard to fit it up there because it pokes into the gum.. I swear it didn't do that before.
I'm guessing I have some sort of infection or something, but I don't understand how I got it or why. Has anyone had anything like this before? It's starting to drive me mad, the pain isn't severe, but it's starting to bother me and now I'm scared all my teeth are going to fall out!

I'd love to hear from anyone who has experienced something similar :S
