I've had braces for a little over 3 months or so, and i admit i haven't really flossed them, but my gums..

they keep reddening and look as if they're fluffy or something and everytime they're touched they redden and look as if they have peeled, except no blood comes out. (i dont know if the description is accurate enough) Is this normal? and i have a hard time flossing too..so when ever i try to, it leaves a sort of stining/aching feeling.
