Ever have any harsh effects from mouth wash? Last few nights I've had a little blood when I brush my teeth. Of course thats not a crazy thing seeing as I scrub my gums a little as I should. But 2 nights ago I didn't scrub them hard at all, and when I spit out my toothpaste, the saliva came out bloody. I mean like nosebleed, run down the back of your throat, full on blood. It wasn't coming from my stomach or throat as best I could tell but I could NOT identify the source. I didn't even hit a tender spot or hurt myself at any point while brushing. Last night was a little pink again(little more then the usual gum thing). This morning I was sitting in class and felt something odd in my mouth. I moved it with my tongue and realized it was skin off my gums. I pulled it off and confirmed it was just that. Now the reason I say this is, I just switched to a new mouth wash a few weeks ago. Its Listerine(which I've always used) but its a pre-brushing whitening stuff. Only thing I can figure that is causing this stuff is the mouth wash. It doesn't even burn the gums or tongue as much as the normal mouth wash is the odd thing. But it foams up big time. So again, anyone ever had a similar situation and figure it to be mouthwash or something else? I don't chew tobacco(did very very infrequently a while back but not for a long time) and I very rarely smoke(had one this past week which was probably the first in 6 months).
