This document summarizes the history and benefits of chewing gum. It discusses how ancient Greeks and Mayans chewed resins and saps as early forms of gum. The first commercial gum was produced in 1848. Modern gum uses chicle from sapodilla trees. Gum comes in four main flavors and has oral health benefits like freshening breath, strengthening teeth, and reducing plaque.
