But then I read about sodium lauryl sulfate found in most of toothpastes was one of the reason for Cankers. I stopped using those toothpastes and thank God I do not get it very often, as I was use to get it about twice a month.
But once in a while I will get it. This time it was on my tongue I read it on this website about Alum and bought it from Food basics. Used it once and seems to be very helpful.
