I have braces which means food gets trapped really easily but it is difficult to floss. As a result I have inflammed gums, which often bleed, despite brushing after every meal. Now I use a HUGE scoop of baking soda in a sip of water (so its like a runny paste) and swished it around in my mouth for a couple of minutes. My swollen gums went back to normal imediatly after and have stopped bleeding. It leaves a salty taste in my mouth but I avoid rinsing after the baking soda.
