Mastic gum Vs Jaw trainer

[HONEYISGOOD]

Title
Want to know whats better for Massaters and jaw development, I heard Bojack say mechanical constant stimulus grows jaw but he calls mastic gum cope which is weird as its constant mechanical stimulus.
Are both the options cope if not whats better?

furthermore is their anyway to get forward growth or jaw devlopment through other routes perhaps hormones
