Enjoy a fresh approach to oral care with Underbrush Gum’s Mastic Mint. This hand-crafted gum blends xylitol and erythritol—shown to help maintain tooth mineralisation when used in place of sugar—with a crisp spearmint taste. The natural tree saps create a satisfying, long-lasting chew, while the botanical blend brings a clean, refreshing feel to your daily routine.
Perfect for life on the go, Mastic Mint is gluten-free, cruelty-free, and designed to fit seamlessly into your oral care habits. Chew your way to a cleaner, fresher mouth—anytime, anywhere.
Underbrush Gum was created to be a natural, effective alternative to conventional gum—free from plastics and synthetic chemicals. Founder Nathan spent nearly two years perfecting the first remineralising gum, designed not just to freshen breath but to actively support dental health. Made with hydroxyapatite, mineral-rich clays, and natural tree resins, it helps strengthen enamel and promote oral wellness. More than just gum, Underbrush is a symbol that small, consistent changes lead to lasting benefits.
