How do you keep gum fresh?
What causes bad breath (and how to get rid of it)
Storing Gum at Home. Keep the gum in its original packaging. Gum is packaged to maintain freshness, so it makes sense to keep it that way until you're ready to chew it. If your gum package is sealed in a plastic overwrap, keep the overwrap in place until it's time to grab a piece of gum from the package.
