Humans chew gum primarily to freshen their breath, combat bad tastes, or simply as a pleasurable habit. The act of chewing gum stimulates saliva production, which helps to wash away food particles and bacteria from the teeth and gums. Chewing gum can also help to neutralize acids in the mouth, reducing the risk of tooth decay. Additionally, some gums contain ingredients that can help to whiten teeth, strengthen enamel, or provide a cooling or tingling sensation. Chewing gum is a popular and convenient way to maintain oral hygiene and freshen breath.
