Okay, i have tried everything under the sun... including almost all of the remedies shown here but didn't get any real relief of prevention until i tried one thing... a supplement called lactobacillus acidophilus. i use the extra strength one. it is amazing! i used to get 5 even 6 sores at a time! i stayed with several all the time. now after being on this supplement i rarely get any. it has now been three weeks and i am still canker soar free. if i do get one it barely bothers me and is gone in no time. i have done alot of research on this and i promise it truley works. i was told by a doctor that canker sore also come from a build up of in yeast in your system so i was told to eat yogurt everyday but i felt i needed more (i also got tired of eating it everyday) so i found what was in yogurt (probiotics) and found an extra strength formula because my outbreaks were so bad and it really worked!!!!!! please try it....you will be amazed! remebmer to keep the bottle in the refrigerator and give it a few weeks to really start working...also remember to take it every day!!!! good luck!
Green Tea

I noticed my relatively new habit of drinking green tea is drastically affecting the frequency at which canker sores appear in my mouth. They now seem to form only in the upper part of my mouth. Swishing tea on the sore greatly reduces the time it takes (24-36 hours) for it to heal. It's amazing to find this out after years of dealing with them.

Take one capful of H202 and hold in your mouth for 10 minutes daily, then spit it out. No more canker sores and your teeth will be whiter without expensive pastes.
L-Lysine

My daughter and I would get canker scores often, until a friend told me about Lysine. We both take one a day, and if ever one starts to appear, then take 2 pills and the scores are gone. I told a great friend who had very dry lips and the lysine has worked for her as well! Love it! The pain is gone!

L-Lysine

My 5 year old daughter came down with a horribly serious case of canker sores. Her mouth had several sores on her tongue, cheek, and gums. Her gums were so red and swollen you could barely see her little teeth. Her breath was absolutely terrible and she barely ate or drank a thing. Finally after a week of different attempts, we had her gargle with 6 drops of tea tree oil in 4 oz. of water three times a day, gave her half an adult dose of L-lysine crushed up into water once a day, gave her a homeopathic every hour and had her drink 16 oz. of water with acidophilus/FOS throughout the day. We kept her completely off of sugar, dairy and meat and mostly she ate cottage cheese and plain yogurt. Within one day she was so much better and finally eating and within 3 days totally better!

My nurse practitioner recommended L-Lysine for my debilitating canker sores. They would last for weeks and were so bad that the pain extended to my neck and lymph nodes. I couldn't even eat without excruciating pain. When I feel a canker sore coming on, I take 1 gram 3 times a day and the sore is gone within a day or two.
Tea Bags

My husband told me to put a tea bag on my canker sore. It definitely took away the pain! As for curing it, I think it speeded up the process. The tea bag remedy is good for any type of mouth sores because of the pain relieving effect. I usually use black tea, simply because that's what I have around most of the time. Green tea also works, and I'm sure any kind will probably do the trick. It is not necessary to steep the tea first, however it does work better if the bag is already wet before applying. If the strong taste is too much for you, drinking brewed tea also works if you swish it around over the canker sore while you drink it. However, it's been my experience that the tea bag directly on the sore is much more effective.

I had cankers until I started eating yogurt with active bacterial cultures. It really works. One small yogurt a day & once there gone, keep eating the yogurt & they won't come back. I have done it.
Cloves

I used many different things for the big sore on my tongue. Nothing would work, until I started to use the clove powder.. It started to work immediately.
I've learned that canker sore can be caused by bacteria or many other causes. In my case, it was bacterial, from a tooth infection. In 2 days it shrunk 80%..another 2 days later it was gone.
Peppermint Oil

Peppermint oil seems to have shrunk the canker sore I had. I was putting a drop of the oil in my mouth once a day. That was three days ago, the sore is gone. It had been there about three days before I used the oil.
I mixed several drops with tea tree oil in a capsule and inserted it to see if it would get rid of what appears to be hpv on my cervix. That was 12 hours ago and my period has just started a week early.
CBD Oil

I had nasty canker sore on the roof of mouth. I tried everything on here for relief. It all helped some. Then I remembered that I have some cbd oil balm. I loaded up a Q-Tip with it and placed it everywhere I felt pain or tenderness. Went to sleep. Woke up pain free. Like it went away over night. That stuff is the best for any type of skin lesion.
Avoid SLS Toothpaste

Avoid Sodium Laurel Sulphate in foaming toothpaste, cleansers etc. I am a 58 year old female and have suffered on and off with canker sores (aka mouth ulcers) since my teens, although sometimes going for long periods with none. However I have recently had two cankers on the gums of my lower front teeth which just will not go away. Normally a canker sore would last about a week, but I have had these for approximately six weeks. I have been doing extensive research and believe I have discovered the cause : sodium laurel sulphate (SLS). I was using hydrogen peroxide on the sores for healing and also using a purchased baking soda toothpaste,, but did not realise the toothpaste contained SLS. I have also been using a foaming cleanser with SLS on my face which may or may not contribute to the issue. I believe I have developed a sensitivity to SLS and will now need to avoid it. Just thought that might help someone.
Folic Acid

Folic Acid doesn't work for canker sores. Makes them sorer.
Oil Pulling

Hmmm Arnezi, coconut oil had always only given me temporary relief. But this past outbreak disappeared after drinking Oregano tea for a few days. Just 1 teaspoon of plain oregano from the spice jar in a glass of boiling water.
