I think that is highly unlikely. If there is as you say no sharp edges anywhere or anywhere that she could have gotten hurt, then I would say to check for FinRot or just watch her closely, but I don't think that bettas could reach their pectoral fins. (Unless they are "Big Eared" or "Dumbo Eared")
As you can see in the pictures the "dumbo" gene is just a gene that extends the pectorals and makes them larger.
