I came across this site and followed the suggested remedy. I used ACV on my canke rsore last week, I had 3! I had to use 2 Q-tips, each dipped in apple cider vinegar, and placed them directly on my canker sores until they went numb. It took about 6 minutes and it hurt a bit but the numbing really soothes the pain(that night and the next day). My inner lip turned a grayish color and my mouth tasted like vinegar for a bit but the next day, I barely felt the pain. My discoloration went away and the canker sores developed sort of a skin, like when they are healing. I did the procedure the next night and 2 days later(with hardly any pain), all 3 went away!
I have been dealing with these darn things for a long time, most of my life, and I never found a decent remedy. I've tried salt water, baking soda, and various other remedies but none of them helped at all. I can't believe a simple product like apple cider vinegar actually works and quick. I will always have ACV in my cupboard since I am one of the lucky ones to be blessed with these darn annoyances!!!

I must say I was a little skeptical at first. But the ACV truly works with the pain and discomfort. I was so AMAZED at how quickly I was able to relax afterwards. I used the Q-Tip method. Hold on ulcer for 30 sec's, spit, repeat 2 more times. It stung at first, but my pain was gone in less than 10 mins.

Some Ulcers are caused by acid. In this case, ACV will make it worse. For me, the Apple Cider Vinegar fixed mine in 45 mins. Mine was so horrid, it hurt so badly I couldn't even breathe right. This fixed it.

I start taking apple cider vinegar in a glass of apple juice every morning because I had just heard that it was good for you and thought I'd try it. Well I always had about 3 canker sores in my mouth at a time, it was seldom that I didn't have at least one, I have been drinking the ACV daily for about a year now and I hardly ever get them, if I do, they don't last. If I skip a couple days I am sure to have a canker sore. It doesn't make since that drinking something that acidic keeps them away but I'm so thankful that it does!

Apple Cider Vinegar for canker soresI drink ACV for digestive purposes a glass each evening. I have had a hurting canker sore on the tip of my tongue for almost a week and today it was as painful as day one. Slowly drinking vinegar and water combo this eve I noticed that it didn't even burn the sore and actually made it feel better. I held sips in my mouth for a few minutes a couple of times over about a half hour and the pain is far less. Just a couple table spoons in a glass of water. To think I am 60 and am just now finding a remedy of this life long ailment.
