Not likely: Your jaw muscles would tire out before any hint of broadening. However if you chew gum constantly it may increase the size of your jaw muscles which would give the impression of a broadened jaw.

No.: You can chew all the gum you want but it will not broaden your jaw line. Why do you want to broaden your jaw line?

No: It can build up the jaw muscles. A lot of gum chewing can contribute to TMJ problems. I would keep the gum chewing to a minimum. If you must chew gum, chew one that has xylitol as the sweetener. It is a natural sweetener that helps to reduce cavities.
