Natural Canker Sore Remedies: Quick Relief & Healing

Ok I had this terrible sore on my upper lip. I wear braces, so the braces were digging into it making it even more painful. I tried the vinegar and q-tip thing and it really worked! It's been about 2 minutes since I tried it, and I can't feel anything anymore. Thanks so much.

i have two canker sores , one small one on my upper lip and a big one on my lower lip. i used saltwater but it just tasted nasty, stung, and didnt help at all. i put regular vinegar on a q-tip and held it on each sore for a minute. it stung but after another minute it stopped hurting. i could finally put on my chapstick with out using my finger to spread it. i just tried it so im still waiting to see if itll last until tomorrow
