If you can't afford to go get one of those kits at Wal-mart then I have found if you mix baking soda and peroxide and brush it on like toothpaste. It tastes HORRIBLE, but really works...and if you notice your gums turning white right after, don't worry. It is just the peroxide killing the germs (same as if you poured it on an open wound). Just keep rinsing and it will go away.
