I don't want to stress you anymore but personally Id be getting a vet and Xrays asap.
Anything involving the head can potentially be very serious, and although it may look worse than it is, but may also not look as bad as it could be. If that makes sense.
My TB was kicked in the jaw by my little paint 2 years ago and he ended up with a fracture. He was on antibiotics for close to 3 months and the only way you could tell that he had an injury was a slight swelling and tiny bald spot under his chin.
