Avoid SLS Toothpaste

I have had canker sores for a while and had tried a lot of different things to help them. My daughter started to get them at a young age too. We looked around and found that SLS can cause canker sores and we found that it is in a lot of toothpastes. We started using Baking soda for toothpaste and we have not had any more canker sores for over 6 months except for my daughter 1 more time. She missed the toothpaste flavor and she used some of a gel mint flavor toothpast that had SLS in it and the next day she got a canker sore. She went back to the baking soda and it was gone in 2 days and didn't come back. Before she was getting 1 -2 every week now none in 6 months. We just get a small bowl and put some baking soda in it and wet the toothbrush in water and dip it in the paste 1 time and then brush. I learned about it from my grandpa many years ago but never used it. He past away at 94 years old and had almost all of his teeth.
B Complex, Vitamin C

I used to get canker sores, but then I started taking vitamins, particularly a multi-B, plus C and I've never had them since. My doctor recommended the multi-B, plus C supplement. The B also has a nice side effect of improving my complexion overall. For a quick cure, however, I used to put salt on them - it would burn like heck, but then the sore would go away the next day. I also think a crushed vitamin C tablet would be good.

Brush With Baking Soda for Canker Sores
There is an actual phisical layer of pathogens in the canker sore. If you just put the products like baking soda there, you will not be able to penetrate through this layer. Hence the best approach would be to brush your canker sore with your baking soda, or whatever product you want to use to kill the pathogens. Using this technique will kill your canker sore instantly.

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!

I had a canker sore in my mouth last night. It was red and inflamed and had a white patch in the middle. But my son had just put a coat of finish on my kitchen floor and I couldn't access any of my herbs, charcoal, etc, since they were in the kitchen. I was looking around my bathroom for something I could try and saw my home made tooth powder. Baking soda!! I put some on the spot three times before bed. Tonight I realized it must have worked. I looked in my mouth and saw no sign of the sore! For the record, my tooth powder also has bentonite clay and peppermint essential oil in it. But I think it was the baking soda.

I tend to get canker sores when I eat too much sugar or if I eat corn syrup at all. I recently went on vacation, ate out a lot, and inevitably got a sore. This one was worse than usual and progressively worsened over the course of a week.
When I returned from vacation and ceased any excessive sugar intake I decided to try treating it with baking soda. I applied a small amount of baking soda directly to the sore in the morning. Twice throughout the day after eating I mixed baking soda with water and rinsed out my mouth. Before bed, I applied baking soda to the sore again. The last application caused it to start bleeding! By the next morning my sore looked more inflamed than before and I even had another one forming!
Needless to say, it didn't work for me. I hope others have better luck with it.

My husband has suffered from Canker sores for many years. They would pop up almost immediately with certain tomato products and raw red high acid tomatoes. When we learned about baking soda for balancing pH, the logical conclusion was to use it to fight the canker sores. I can testify that if he knows one is on the way, the baking soda water will stop it in its tracks.

Using baking soda worked for me. I had a canker sore that kept getting worst despite the fact I was applying hydrogen peroxide. So I looked online and saw that baking soda also worked as a treatment for some. I applied baking soda once or twice a day for three days and it completely healed the sore.

Had tried many of the suggestions here, so I was an 'experienced' patient. But this last episode was getting agonizing, allergies caused me to bite my tongue 3 wks ago. Had been to the clinic and got a little relief. Called Primary Care Physician and got a little more relief several days ago. Today .. Nothing had really helped and pain was getting worse. FOUND THIS SITE. Had not heard of the alum/baking soda cure and since I was in no shape to go pick up some alum, used my handy large size of baking soda to try that out. Did it once .. Seemed to help a bit. Waited a little while, rinsed with salt water (which I had been doing from the beginning) and applied more baking soda. This time it Burned - but not for too long. Now my throat is sooo much better. I can swallow again and the pain is not radiating down my neck past the lymph nodes - one morning I was awakened dreaming I had the mumps again. I know that the yogurt works. I had gone so far as to make it myself when my kids were little - it was not as readily available as it is today. I was just too far run down this time for any of my usual remedies to kick in. Thank you for this site. It was just what I had hoped to find when I started looking days ago!!

I have these last couple of months been getting canker sores. I have never had them in my life, but have just started getting them out of the blue. I found this website and i have tried everything on here, all but the baking soda i tried that last. Let me say NONE of the other things worked for me, but oh my gosh the baking soda works wonders!!!!
The pain was very VERY bad and i didn't know what else to do, i even tried over the counter things and they didn't work in anyway, but the baking soda did.I also found the baking soda helps if you have a toothache too, in short baking soda is amazing and i would try it before anything else.

Baking soda cured my canker sore within 24 hours. I had major pain on the side of my tongue to find a canker sore it was so sore I couldn't hardly swallow. I took 1tsp of baking soda and 1 tsp of water and kept it in my mouth as long as possible. I did this 3 times within an hour went to bed and did the same the next morning by dinner time the canker sore was gone! Thank you for this site its a great help.

Out of the blue 4 days ago I got a canker sore that was 1.5 inches large on the side of my tongue. It was excruciating! Last night before bed I tried putting a baking soda paste on it and I woke up this morning and it's almost gone! I am so glad I found this website!!!

Thank Goodness I found this page. I started with two small canker sores a week after my flu shot. I hardly ever have a canker. So, I used Ambesol Max Strength. It burned, numbed, but things got much worse today. Almost two inch long canker on the side edge of my tongue. And three more scattered on my inner front and side lips. I rinsed with the pure apple cidar vineger. It didn't releave the pain. So I tried the baking soda paste. The paste started to tone down the pain. I was at a 10 most of the day. After the baking soda treatment, I am currently down to a 4. maybe less.ahhhhhh

I ran a quick search over the weekend on treatments for chronic canker sores on behalf of my boyfriend who has suffered these painful occurrences since childhood. I came across this site and he decided to try the baking soda paste. It stung at first, but it helped him heal within five days and he's so happy to have found this treatment. Thanks.
