I know this is an old thread, but hopefully this will help someone.
I have finally found a cure and a preventative for canker sores. I have suffered from canker sores my whole life (I used to get at least one or two bad ones several times per month), and so have several members of my family. This has worked for all of us after discovering this 6 months ago.
I put a small dab of toothpaste on my toothbrush, then scoop it in baking soda to get a big clump, and then brush normally. Alternatively, swishing with baking soda in water solution helps, but I find that brushing with it is more effective for me.
No canker sores in at least 5 months! Plus, my teeth are getting whiter and whiter, and my dentist has noticed tartar build-up between dental cleanings is very minimal. It's definitely the way to go - dentists should be telling everyone to do this.
Other things that have worked, but only if you catch them early:
*Baking soda applied directly to ulcer
*L-Lysine 500-1000mg at first sign (not always effective, but has worked many times); twice per day.
*Full spectrum CBD oil applied directly at first sign. (This worked the best for me, until discovering baking soda.)
Hope this helps...

Wow! I never heard of that I Marianne and I’ve had in my whole life. They
say it comes from your mom or dad. It’s a virus. That’s amazing. I’m gonna
try it because I’ve suffered since I was a child my sister, does not get
them, but I have a twin brother and we both get them. I’m 70 now and I’m
still getting them when I get stressed. Thank you for yourwonderful news.
