There has been no evidence that sugar free gum actually whitens your teeth. Regular toothpaste does that.
It can be, particuarly if it's a "sugarfree" or low-cal gum.
Gum with sugar, because the sugar provides flavor to go in the holes of your saliva. Sugar free gum goes away faster because there is less flavor in the sugar free gum.

The reason why you are not allowed chewing/bubble gum is mainly because of it sticking to your brackets (the bit attached to your tooth), not because of the sugar content. However, the sugarfree gum tends to be less sticky and so you would have less chance of it getting caught in your brackets. But I really don't recommend chewing gum of any kind whilst wearing braces..been there, done that! Hope this helps (:
Gum with sugar has real sugar and sugar-free gum has a sugar substitute but it tastes like sugar.

Sugar-free gum typically keeps its flavor longer than regular gum. This is because sugar-free gum uses artificial sweeteners like aspartame or xylitol, which are more stable and do not break down as quickly as sugar. Regular gum, on the other hand, uses sugar as a sweetener, which can dissolve and lose its flavor more quickly through saliva and chewing.
