Ohmygod I use that Rembrandt toothpaste too! It's the only thing I've found that works. But even though it's crazily expensive, I think it's worth it, to avoid having those damned canker sores, which used to torture me all the time. Man. I never thought I'd be so into a product, but I am. Canker sores begone!

But now I'll look for Welleda, just to try that out.
