Chewing & chin projection

[mtcut3plush]

I was wondering if chewing hard gum (with molars) promote better chin projection / froward growth ? and if anyone has noticed any improvement in chin projection with chewing
thanks in advance

Maybe if you're young you can guide healthy growth but as far as I know chewing will only help with jaw width projection through training masseters. You'll need some form of surgical intervantion or jut frauding for chin projection
