Well, can you describe this ulcer a bit? Mout ulcer may be from candida, Crohn's disease, celiac disease, vitamin deficiency, anemia...
Any other symptoms?
Some basic blood testing would be needed.

I think it's time you get an appointment with a gastroenterologist. If it is candida, it may be because of lowered immunity, yes. But it could be an unspecific ulcer which often occurs in Crohn's disease for example. This would need further examination, stool and blood tests are usually done first.
There's no way to say, try this remedy and it will help. You need to find out what's behind.
