anekdotal evidence of a related principle - after several years of regular hiking i had noticed some slight bone shape changes - a bit larger kind of protrusions where tendons/muscles attach to the bone, so it doesn't sound surprising that the chin bone would respond to the chewing load, especially in the younger years when the things have much higher plasticity. It is also pretty known that a loss of tooth is with time followed by a local bone loss.
