Seems plausible, I’ve wondered if the outward-pulling force you get when you try to rip off a piece of big chewy food has any effect, but I don’t think it’s been studied and it doesn’t seem super likely. (Healthy people chew with a rotating jaw motion, not an up-and-down motion, so any chewing should have outward-pushing force because of that.)
Does chewing sugar-free gum suffice? Seems simpler
I chewed sugar-free gum all the time growing up and didn’t need braces or wisdom teeth removal
