What could be the cause of a large and bleeding sore on roof of mouth? - list walk in clinics toronto

My father noticed a sudden red large, shallow wound on the back of the roof of the mouth. He began to bleed and he is now a walk in the clinic. What could be the cause of the disease so quickly? He started a new medication, but I am clearly right when it started. But, he says, medicine is not a list of a pain in the mouth as a side effect, so who knows. I just hope that all is well with him. It is in a few drugs.
