After a serious of bad choices and some dumb mistakes i lost my job and couldn't afford my monthly trips to the orthodontist, (never choose Western Dental) if you don't pay they won't see you... So after a few months my gums were bleeding and my teeth were shifting and I was in tremendous pain.. A friend suggested hydrogen peroxide and after I tried it. it worked wonderfully and my teeth stopped bleeding after a few days. I heard from some people it even helps whitten your teeth. I can't tell with all this metal but I know my teeth are not bleeding and I feel so much better...
