Sugar-free gum is a type of chewing gum that does not contain sugar. Instead, it uses artificial sweeteners like aspartame or xylitol to provide sweetness without the calories associated with sugar. This makes it a popular choice for those looking to reduce their sugar intake or manage their weight. Chewing sugar-free gum can also have dental benefits. It stimulates saliva production, which helps neutralize acids in the mouth and can reduce the risk of cavities. Many people enjoy it for freshening breath and as a convenient way to satisfy cravings without consuming sugar.
