I'ld say that the resulting broken jaw would be as empirical as it comes.
If you wish to take that and still say "it could all be an illusion and I'm just a brain in a vat!", I'ld say "fine... now go to bed".
As I said: insofar as I can prove anything.
If you are going to simply call literally everything a subjective experience because anything and everything you can see, hear, feel, etc is inevitably going to find its way to your brain through your senses, go right ahead.
I think it's a pretty useless way to play the game.
Go to bed.
