Not exactly your question, but it is well established that chewing/gnawing as a (young) child is directly proportional to jaw length (I guess you could say prognanthicism to some degree) - but specifically the amount of space available in the mouth for teeth. People who chewed/gnawed on ie a rug or something as a child are less likely to have crowding in their mouth and more likely to have eruption of wisdom teeth without an issue. This makes sense - using your muscles in these ways especially during significant developmental stages changes the release of trophic factors which in turn change development.

Really it’s no different from how someone who uses their body differs from someone who is sedentary all the time but in this case the timing of the ‘intervention’ causes big downstream changes
