What is the difference between Gum and Sugar free Gum

       I have heard that you can have Sugar-free gum with braces, but is that really true? I have seen and tasted the difference between gum and sugar-free gum and there isn't really a difference, actually Trident suger-free gum is sweeter then regular gum. As you can see you can't really tell the difference between sugar-free and regular gum.
