A. welcome to my life! every time the air get's a little dry i get 1-3 aphthae and can't eat for the next 4-6 days. so i investigated a little, and i'm sorry but right now no one really knows what causes them. they know that from some reason the body get's an immune reaction in the oral mucosa and that causes an ulcer. but a friend of mine went to an Ayurveda therapist that told him to stop eating tomatoes and eggplants (in any way, cooked,baked,fried) and he says he stop getting aphthae. so you might try Ayurveda for prevention. it could help...
