I've always thought I was mildly allergic to some brands of toothpaste, wonder if this was related.
My symptoms were sores in the corners of my mouth/gums - took a couple weeks before they'd show up and the only way to get them to go away was heavy rinsing with water after brushing (which is not recommended because of fluoride mineralization)
Switched to Tom's toothpaste (with fluoride) a few years ago and have had 0 issues since

make more foam when you brush
I always buy a specific brand toothpaste (turns out it is SLS free) but broke from my routine and bought crest or colgate or something. I use a small amount but I have to empty my mouth of foam midway through brushing. I hate it. Gross.
I also have a canker sore but have been brushing my teeth more often (with the crest) thinking it would help. I guess not.
I have another toothpaste (clinipro) which is not foamy enough, I always feel like I'm running out of toothpaste as I'm brushing.
After JASON discontinued the toothpaste I had been using for quite a while, I found Burt's Bees and liked it. However, I recently found out by scanning it with the Yuka app that the Burt's Bees paste had some other bad ingredient. So now I've switched to Hello toothpaste which seems to be pretty clean. If you ever get interested in trying another paste I would suggest Hello.
I'm quite attached to sensodyne since I have gum/cavity issues (genetics..). I want the science in my mouth. I don't know how much of that belief is just good marketing but I'm afraid to test it.
I totally understand! After some people mentioned Sensodyne on this thread, I looked it up and indeed some Sensodyne "flavors" (but not all?) are SLS-free. From what I recall, there really is an ingredient in Sensodyne that reduces sensitivity. I don't know about gum/cavity issues though. Maybe your dentist can confirm. Take care!
I'd be curious how others feel but personally painfully brushing the sore causes it to heal the quickest in my experience.
Not joking
I have found mouthwash to be the best solution. If you feel one coming on or bite you mouth and think you might get it, mouthwash ASAP.

you should also know that people in the past would just brush with a fresh twig and maybe some salt, and their teeth were absolutely fine within the limits of not having any sort of dental care beyond "pull a bad tooth out with pliers".
and nowadays we have fancy electric toothbrushes that are way more effective than a twig, so really i see little reason to use toothpaste beyond society as a whole having been convinced that if your mouth doesn't taste like mint it's DISGUSTING.
