Chewing gum can be used for fresh breath when brushing is not possible, it has some medical benefits, and can be enjoyed for fun in different flavors. Sustainable gum options are becoming available that use more natural and biodegradable materials with less sugar. While chewing, gum provides flavor and can have utility like whitening teeth. After use, gum is challenging to decompose and can become litter, though some turn it into art or find other innovative reuse approaches like adding stickers. Developing more sustainable and recyclable gum options could help address this issue.
