Chewing gum is a soft, cohesive substance designed for chewing but not swallowing. It is typically made from a mixture of gum base, sweeteners, flavorings, and softeners. The gum base is often made from synthetic materials or natural latex, which gives it its chewy texture. People chew gum for various reasons, including freshening breath, reducing stress, and improving concentration. Some types of chewing gum, like sugar-free gum, can also help prevent cavities by stimulating saliva production. Chewing gum is available in many flavors, such as mint, fruit, and cinnamon.
