How Much Force (PSI) Do the Teeth Apply to Each Other when Chewing?

What causes the bone to deteriorate after teeth are removed? Does pressure on bones increase the density of the bone? What exactly attacks the bones in the jaw that can cause tooth decay? I sincerely appreciate your time & answers.

What is the average biting force ?

Average bite force is somewhere around 150-500psi.   This s a lot of force and its higher on the back teeth.  The bone that holds teeth deteriorates after extraction because the bone is not being stimulated.  Bone resolves when it's not stimulated with some force.  The skeleton of an astronaut weaken due to lack of gravity in space in a similar manner.
