I used to get canker sores every once in a while.

I cut out SLS by purchasing Toms toothpaste, and that helped a lot.

I would still get them though, maybe twice a year.

The thing that finally fixed it was almonds. I stopped eating almonds and I’ve never had a canker sore since.

No idea about canker sores but cold sores outbreaks (caused by the herpes virus) are linked to almonds consumption because they are heavy in arginine and don't have much lysine.

Same effect for me. SLS toothpaste gives me canker sores. Or at least prevents their healing

I also had to switch from SLS toothpaste. I used to use a thing called Rembrandt gentle, but they stopped selling that so I started using something called Squigle, which has atrocious branding but is just fine.

I have some amount of uncooked nut allergy and chocolate allergy that causes similar effects to SLS toothpaste. I'm still trying to figure it out.

I wanted to pass along this product I found a few years ago that really changed the game for me though, check out "Durham's Bee Farm, Inc. Canker-Rid."

This has been a problem for me since I was a kid, and all we had back then was Campho-Phenique and pain killing gels. Those things were / are awful. This bee stuff is absolutely amazing. 10/10 check it out.

I'm also SLS sensitive. I found "Verve" toothpaste on Amazon. Reasonable minty taste, cheap, and SLS-free. There are options out there but you really have to search hard for them.

I've had mouth ulcers (canker sores) all my life.

Things I've found that cause them:

- Pineapple

- Lemon/Lime juice

- Chilli

- Sometimes Chocolate

Things that prevent/reduce them:

B6/B12/Folate

Same here. Took me two decades to figure it out.

Hardly ever get them anymore since when it was a weekly occurrence before.

There aren’t many SLS free toothpastes. In Europe I found Elmex and in the Americas Sensodyne (not all, check ingredients)
