Baking Soda

Since childhood I have suffered from mouth ulcers. Usually rinsing with H2O2 works by rinsing several times a day and before going to bed. The next day the ulcer is nearly gone or completely gone. But not this time! Sometimes when my seasonal allergies kick in I get a patch of ulcers. This spring has been the worst ever. Ulcers popped up on the left side of my mouth on the cheeks, gums and under the tongue. So painful and the H2O2 was not working at all. So I came back to this site where I have learned so much over the years -- thanks to all the contributors! Decided to attack the ulcers by taking Echinacea, Lysine 2000-3000 mgs per day on an empty stomach and applying baking soda to all the areas. The first day I got immediate relief from the pain and inflammation on the left side. Kept applying baking soda all day. Slept better that night. Next day the left side was on the way to being healed BUT new ulcers emerged under the tongue and along the gums on the bottom row of teeth as if they were marching to the uninfected right side of my mouth. Yikes! Continued the above protocol plus brushed my teeth with baking soda and continued to place a half teaspoon under the tongue and between my bottom lip and lower gum. Good news. The new ulcers begin to recede with each application of baking soda. Thanks Earth Clinic -- God bless you all!

Thanks for those sharing about the baking soda remedy, I have been bothered with several canker sore in my mouth and cheeks in the last few days and they were very painful and have lost my appetite in eating. After trying a few solutions, they didn't really work for me and out of desperation, I applied some baking soda paste over the sores last night, while they haven't gone away, it did reduce the level of pain and hopefully they wil go away soon. Big thanks for sharing!
Iodine

The best for canker sores is Lugol's Iodine 5%. Take 5 drops in the morning on empty stomach for about 2-3 weeks, they will never come back.

My 6 year old son got a canker sore a few days ago. The pain was getting progressively worse. I tried rubbing some coconut oil on the sore at bedtime... it was gone by morning. Would use it again as he gets canker sores frequently.

Raw natural honey worked very fast for me. I had a very painful canker sore for over a week. I tried salt, baking soda and collodial silver with no improvements. I read on here to try raw honey and I noticed relief the very first day. Within two days of dabbing raw honey on it several times per day the sore was almost gone. It was a huge relief and a yummy remedy!

I always take lysine for canker sores. Recommended by my Dr 40 years ago. Also use peroxide. Usually goes away within 5-7 days.

Canker sores - I started getting them when I was 5 yrs. old. I was eating alot of chocolate. I had a mouth and throat full of canker sores. This progressed as I got older. Early twenties, I would eat hot dogs and bologna....and more canker sores came. I started noticing the connection. I also started doing alot of research on this and many other health related things. What I came across was a book on Amino Acids and how they work and what symptoms you may have if you are depleted. Aha, when you have too much Arginine and not enough Lysine...they will come.
At the tiniest of inklings that I'm getting a canker sore, I take L-Lysine 2 grams (4 - 500mg) capsules on an empty stomach, 3 times a day. I have had a bit of runny stool, but it goes away. The next day, the canker sore has disappeared. I am so grateful for Lysine.
Folic Acid

Folic Acid doesn't work for canker sores. Makes them sorer.
Avoid SLS Toothpaste

I don't know if I am allowed to say here, but it is Swanson toothpaste. It is really good and affordable. The taste is much better than other I have tried.

What toothpaste did you switch to? I'm looking for a good toothpaste, and if it can help us stop having canker sores, that would be great!

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.

I get huge canker sores that are extremely painful sometimes, and this last one I swished coconut oil 1 tablespoon with 1 drop of oregano essential oil for 10 minutes in my mouth and then spit it in the trash. The pain was gone. I did this 2x a day for 2 days and it was gone. I was so happy I found something that worked.

I had suffered for more than 20 years with moth sores or canker sores. I talked to so many doctors. Some of them talked to me about drinking more water or taking some vitamins. I tried everything. Nothing worked until one day I read somewhere about SLS (sodium laureth sulphate) which is a chemical that makes the toothpaste more foamy. I switched to sls free toothpaste, and guess what? I have never got them again.

Magnesium Citrate

Regarding mouth & tongue ulcers, the round white ones that hurt and take some time to resolve:
I am not used to having such ulcers but a change in diet, and an unforeseen minor setback in health status, and I experienced mouth pain bad enough from one of these ulcers to cause me complete physical discomfort including headache. I tried numerous remedies that have worked for others, got minor temporary relief-- but the ulcers remained unscathed, and the pain came back intense as before. Then I held a QTip coated with magnesium citrate powder directly onto the ulcer for about 2 or 3 minutes. Ulcer went away within 24 hours.
A month later, on the other side of my mouth, another ulcer, smaller, and with the exact same result when I dipped my finger in the Mg citrate and then rubbed it on the ulcer: No pain within a day.
This may be useful for others.
Salt
Posted by Grace (Hardy, Va) on 01/19/2016
Use 1/2 teaspoons of salt and mix it with 1/4 a cup of water and the pain will go away. It doesn't get rid of the canker sore, but the pain goes away long enough to eat. I suggest doing it right before eating, but you can do it however many times you want to during the day. It really helps.
Garlic

I had a canker sore in mouth right where my gums and cheek meet. I chewed one garlic clove in the morning and once at night and within three days it was non-existent.
Salt

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!
L-Lysine

Lysine, an amino acid, is brilliant to alleviate mouth ulcers, just use recommend dose on pack, usually about 2 X 1000 mg tablets. You can use them continuously to help prevent ulcers if you are prone, or else just when you get an ulcer. I've tried everything, including soluble steroids but listen works brilliantly. Within two days the ulcer will have virtually gone. Corsodyl mouthwash is also quite good for bringing instant relief.
