Hi there and thank you for your post! With what you are describing, I would think either behavioral or that something is going on inside his mouth or with the jaw itself. I would have your vet take a look at him to figure out the cause. If something is wrong with his mouth or jaw, your vet may want to take some x-rays of his head to make sure there are no major concerns. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns.
