[YEA]  Probiotics for Mouth Ulcers: This is so painful at first, if you're dealing with a large ulcer, but it works everytime. Open up your probiotic capsule(s) 1 or 2 is good, pour onto a dish, add only a few drops of water at a time to form a kind of paste, then, using clean hands, use your index finger to scoup up some of the paste and push it up into the sore. Try and keep from swallowing for a bit (you'll get a little drooly) between 2 and 5 minutes is good, but the longer the better I suppose. You want to do this 3 or 4 times/day.... but I've never had to do it for more then a day, once I had one about the size of a quarter on the roof of my mouth and that was nearly gone after the second treatment! It does hurt terribly bad, but only while your pushing the probiotics into the wound.

[YEA]  I use probiotics 2 capsules a day to control canker sores. I used to get them from eating any kind of nuts or bread/pastry with nuts. For 2 months now I have been eating the nuts without the canker sores.

[YEA]  Hi, from Georgia (Rep. of).

Here is the best and only remedy for canker sores in your mouth - dry Sage leaves. Chew just a few of them each time and all day long if you like and all year long if you like with no side effects. Don't use a dried stem of Sage to avoid scratches that can worsen situation and prolonged healing. You WILL get rid of canker sores from a few hours to several days in severe cases. Repeat treatment if any. Good luck!

[YEA]  Just tried the salt-on-canker-sores. I had read that it is to be put on every 15 minutes.

So I dabbed a bit of Celtic Salt on it every 15 minutes, for as long as I could stand (about 10 seconds) before rinsing my mouth . At the hour and a quarter point, meaning 5 applications, the skin there started feeling a bit rough, so I stopped, and now it feels much better!

[YEA]  I'm subject to ulcers on the roof of my mouth. I try to avoid prescription meds. I recently discovered that swishing warm salt water in my mouth after brushing was very effective. Bananas are quite effective too. Recently, my gums and roof of my mouth both hurt horribly! Out came the salt water. I'd also read in "You, the owner's manual,"that taking 81mg. baby aspirin is extremely helpful. The problem is nearly gone, and I'm sleeping better, too! I can't ask for more!

[YEA]  I occasionally get canker sores every now and then. One day about 6 years ago I asked my grandmother, "grandma do you know how to get rid of a canker sore?!" She told me to either gargle some salt water or dab a little bit of salt directly on the sore. Of course it will burn and sting enough to make you want to possibly just bite your tounge, but after a minute or two the pain from the salt and canker sore subsides. Keep applying the salt each time the pain may come back, and soon enough your canker sore will be gone.

[YEA]  I think that if you put on enough salt at night, by the morning it should be gone. I use sea salt though!:-) if you use table salt it might be different.

[YEA]  I had several canker sores on my tongue and cheeks which made eating difficult. It was painful! I tried the salt-water remedy and in 3 days, the sores are gone! Thanks

[YEA]  two words: salt water! Don't believe me, try it

[YEA]  What you do is get a cotton swab with salt it won't cure it for a while but it will make it stop hurting. Also you can light up a match, blow it out and then put it on your canker sore and it will be gone in one to two days.

Silver Nitrate Sticks

[YEA]  I work in a dentist office and whenever I get a horrible canker sore I use Silver Nitrate Sticks. It burns for a little bit but then forms a wet scab over the area. I asked one of the Dentist at the office I work in why this works; and he said he had heard at in a CE class that it's because the canker sore is cause by a virus and the body does not heal the virus it just runs its course, so the Silver Nitrate injures the area, causing the body to heal itself. Although it stings and makes your mouth taste a little like an ashtray for about five minutes, it's totally worth it.

Where can I obtain silver nitrate sticks?

[YEA]  When I underwent chemotherapy, I would also get mouth ulcers. The doctor gave me a prescription for a mouthwash, but it was useless. Rather than suffer for days with mouth ulcers, I decided to cauterize them using silver nitrate sticks. Yes, this is painful but only for seconds as compared to 10 days of daily suffering with mouth ulcers.

Sore Throat Spray

[YEA]  I used a generic sore throat spray with antiseptic in it. Sprayed it right on my canker sore, and it stopped hurting right away, a few hours later, it was slowly shrinking... about 24 hours later, it was completely gone. It also helps that the pain goes away almost instantly with it too, since it is a numbing solution.

[YEA]  Hi All ; It's been a 45 yr. search for me. I hope to shorten your suffering. I'll just give you the answer first, or the one that worked for me. Folate/Folic Acid. I need extra, more than the RDA of 400 mcg. , I need 800 mcg. daily in a supplement.

Canker sores are a common sign of B12 deficiency, so that's another supplement to consider, especially when one takes Folate, because they are interdependent. Sublinguals are easier for the body to use than oral types. I take large quantities, but I believe most people may need less. Supplements work best when we find our own numbers. My guess is that most people will respond to 500-1000 mcg. daily.

Zinc is another supplement that is suggested for canker sores. The RDA is approx. 15 mg. Daily. When I look at the zinc content of foods, it seems difficult to consume that amount, so I supplement with it, 15mg. 2-3 times weekly. But I'm considering a test just to see if I'm in the range somewhere.

Folate may also help with other lesions/ulcerations along the GI tract, I've read.

I wish I could give this information to my 10 yr. old self, when I lay crumpled on the bathroom floor with a stick of silver nitrate that only made the pain worse....
