This website is great! I went to google looking for a cure to my nonstop reoccurring canker sores and i found this site that recommended Apple Cider Vinegar so i went out and bought it and after a few treatments of the q-tip they were cured. I just want to say thanks again for finally giving me a way to cure my canker sores. I will be recommending this site to everyone

Okay so I have the hugest canker sore between my gums and cheek... I love acv for everything. But when I tried this tip last night my mouth was in so much pain I couldn't sleep! I felt the pain right down to the root of my teeth, even my hair hurt. Finally I had to rinse my mouth with warm salt water. So if this works for you then great but personally it was NOT a good experience. However I will continue to take it for other things.

First, I want to say that ACV worked like a charm on my recurrent mouth cankers, and using a toothpaste w/out SLS keeps most from recurring. Second, I want to address Ted in Mt. Horeb, Wisc and his Nay vote on ACV: I too had what Ted talks about, but it turned out to be a tumor, which eventually turned cancerous. He may want to keep an eye on that mouth sore.

Putting apple cider vinegar, or any vinegar on a canker sore will only make it worse. Apple cider is very acidic, and acid makes the sores worse. You should avoid orange juice, tomatoes, vinegar, etc.

Vinegar contains malic and acetic acid, but causes an alkaline response in the body. You need to dilute it before applying.

Do some research please before spreading untrue recommendations. I have cured many conditions using apple cider vinegar, but you need to use care and use quality vinegar that has "the mother" (culture) in it.

Read the other posts about cures. Maybe you had something other than a canker sore? Proper diagnosis is important to proper application of cure.

Be well.

I am prone to canker sores when under lots of stress. While recovering from my first bad illness in 4 years (I almost never get sick) I developed several nasty canker sores in my mouth. I saw that many people had success with ACV, applying it with q-tips and cotton balls. Since I had 4-5 canker sores and was impatient, I decided to just gargle with ACV for about 3 minutes, thinking that would be more effective. Well, the canker sores certainly got better, but the prolonged exposure to ACV burned my tongue and every surface of my mouth. Now it's the day after and I can barely taste anything, eating is an unpleasant chore and anything acidic or spicy is quite painful. When not eating, the inside of my mouth feels like it was soaked in tannins, which is also really unpleasant. So, if you're going to use ACV for canker sores, be smart and apply it ONLY to the sore as it will burn your healthy mouth tissue.

I am so glad I found this site! I had a terrible canker sore on the side of my tongue that kept hitting my molars, could barely eat or talk it hurt. I put _____'s apple cider vinegar on a qtip and held it on the sore for about 1 minute and then repeated twice and then again before bed. I did this 2 days in a row and it is now gone. I felt immediate relief and I could see it healing right away - it only took 2 days to heal and it has taken over a week before. Thanks for this article!

I had a terrible canker sore and used so many over the counter medicines. I found this article and tried the vinegar. It DOES work.

I've been suffering from a tough and very painful sore for over a week. It made me irritable because I couldn't eat, sleep, talk or even smile. I tried Hydrogen Peroxide, Zilactin-B (made it worst to me), wet tea bag to no avail. What worked? Holding my head to let a tablespoon of ACV sit on the sore for about 30 seconds, spit then repeat. The healing began immediately. It is amazing and I'm a happy person again!

I'm a big believer! I couldn't sleep one night because the pain of the canker sore was just too much! So...I got online and sure enough found another reason why apple cider vinegar is so awesome! I used a Q-tip to dab some of the ACV onto the sore spot and then went back to bed. By morning...VIOLA! The pain was gone. I could see that the sore was still there but that the healing process had already begun. AWESOME! I will be recommending this site to everyone! Thanks EARTHCLINIC!

I used the cider vinegar, and it worked! It tasted and burned really bad, but literally took 2 seconds to stop hurting! .....P.S. Don't listen to any nays, it works great! to answer that one dude's question, i don't smoke anything.

Contrary to this person's advice, you -should- read -all- information that's here. Why? ACV can cure your ulcer if it's an infection; if not, the acid'll make it worse. Try it, but take care :)

So, I've tried the salt water rinses, the peroxide rinses, and I've also tried the baking soda paste applied directly to the canker. Despite my efforts I'm currently going on day 5 of my (first ever) canker sore, and I'm a little sad to report that it's only continued to get bigger and bigger with each passing day. I decided, tonight, to try the organic unpasteurized ACV on a Q-tip, since I've had good results with ACV for other ailments (colds, allergies, acidity/candida overgrowth) in the past. However, when I put the ACV on the Q-tip and applied it to the sore, it just began bleeding all over the Q-tip. I've done it twice and both times it's bled. I mean, it definitely FEELS better, but I'm just a little worried about the bleeding, since it hasn't bled during the entire 5 day run, up until the ACV. Is this normal? Has anyone else experienced this side effect, or should I be concerned? Any feedback is greatly appreciated. Good Luck to everyone in your search for natural cures. I hope you feel better soon!

I tried ACV several times on the ulcers I get very often in my mouth and it never fails. It is amazing. However, I would like to know where I can find the raw organic ACV in the UK. Does anyone know?

I don't know what you people are smoking, but Apple Cider Vinegar doesn't heal canker sores at all, it hurts to use it at first and the relief is only temporary. I actually started to get more Canker Sores from using it. Why do you think an acid is going to help when eating acidic foods is one of the causes?

I tried acv on 3 small canker sores which weren't too painful but bothered me most in the evening. The next morning I got up and they were all bigger and hurt like crazy all day. The acv definately made them worse.

A little different (and more appetizing) then apple cider vinegar, I've found that drinking warm apple cider completely takes away the pain from my canker sore for a good amount of time.

I have a canker on my tongue. It hurt soooo bad. I read this site to try the apple cider vinegar. I left for the store and came home and put the vinegar on a q-tip and put it on my sore. I can NOT believe that it made it feel better right away! The sore is still there (of course) but the pain has subsided considerably!!! AMAZING!

I have suffered from chronic canker sores in my mouth for years. I am now taking apple cider vinegar along with using a toothpaste without sodium lauryl sulphate in it and I am canker sore free!

Apple Cider Vinegar mixed with a 1/2 cup of warm water - swish around in your mouth for 30-60 seconds 2x a day and it will be gone quickly!
