I don’t know what they are either but I know exactly what you are talking about. It is just like a pimple/bump on inside of cheek or lip. It is not the flat, very painful canker/cold sore which will last for a few days. It pops up so quick, it seems, and then disappears in a few hours. But I generally pop it because it is so annoying. I have often wondered what causes it/what it is.
Assuming they are canker sores, one anecdotal way to help is to switch your toothpaste. Most common toothpaste brands have sodium lauryl sulfate in them which helps make them foam. It can be an irritant for many people so switching to a brand that doesn’t contain it might help.
In my case I used to have at least one canker sore almost all the time but I switched to Sensodyne Pronamel toothpaste and now maybe get one or two canker sores a year.
