I have a mouth ulcer caused by my dental brace. My brace has been broken a bit anyway (this did not cause the ulcer) so I'm calling them tomorrow to get it fixed, which means I won't be seeing them till probably next week, so I can't get some of that wax stuff they give you any time soon. Bonjela DOES NOT WORK. I live in the UK so please don't suggest anything that you get in America. Like home remedies? Remember, the brace is going to constantly rub against the ulcer
