Gum flavoring can come in a variety of flavors, including spearmint and MINT. Spearmint is a flavor of MINT that has a slightly sweeter taste than regular MINT, and is often used to flavor gum. MINT, on the other hand, is a flavor that is more commonly associated with toothpaste and mouthwash, but can also be used to flavor gum. Both spearmint and MINT are popular flavors for gum, and can be found in many different brands.
