My bf is suffering from canker sores 24/7. Currently, he's carrying more than 7 HUGE ones in his mouth (5 on his cheek and lip and 2 on his tongue). What's wrong with him? At my advice, he went to see numerous dentists and no one seemed to have answers for his never-disappearing canker sores. He can't eat spicy food, never mind being kissed by me... It sucks. Is there any cure or solid treatment he can get? Somebody please help us or ME!
