Our jaws can only bite upwards. So you can’t actually bite down.
Our jaws have evolved to be able to open wide and move up and down to chew food. Because of the shape of our teeth, the jaw is only able to move upwards and cannot move downwards. This means that our jaws are not able to actually bite down.
