Everyone wants a healthy, radiant smile, but few know how to naturally support their enamel without harsh chemicals or expensive treatments. Remineralizing gum is becoming a go-to solution for people who want to rebuild and protect their teeth while on the go—without compromising on purity or performance.
At Nathan & Sons, we believe oral care should align with the body’s natural systems. Our handcrafted gum, Underbrush®, is designed to be more than just a breath freshener. It’s a daily oral health ritual that promotes enamel restoration, fresh breath, and cleaner teeth—all through the simple act of chewing.
What Is Remineralizing Gum?
Remineralizing gum is a functional chewing gum infused with natural minerals and plant-based ingredients to help restore the minerals lost from your tooth enamel. Every day, your teeth face acid attacks from food, beverages, and bacteria. This leads to demineralization, weakening enamel and increasing sensitivity. Remineralizing gum helps reverse this process by supplying minerals like calcium, phosphorus, and hydroxyapatite directly to your teeth.
Underbrush by Nathan & Sons is crafted with these principles in mind. We blend ancient ingredients like tree resins and modern science-backed minerals to offer a gum that goes beyond fresh breath—it’s an act of care for your smile.
Powerful, Clean Ingredients
Nathan & Sons focuses on whole, clean, and effective ingredients. Our remineralizing gum contains:
-
Nano-hydroxyapatite: This mineral mirrors the composition of tooth enamel, helping to strengthen and rebuild it.
-
Xylitol & Erythritol: Natural sweeteners that help prevent cavities by starving harmful bacteria.
-
Tree Saps: Chicle, spruce, and mastic resin provide the chewy base—natural, biodegradable, and plastic-free.
-
Eggshell Powder: Rich in bioavailable calcium, this gently polishes while remineralizing.
-
Calcium Bentonite Clay: A natural detoxifier that removes impurities and bacteria.
-
Ceylon Cinnamon or Organic Mint: Flavorful and antibacterial, offering freshness without artificial additives.
Each batch is made with care and integrity. We never include artificial colors, flavors, plastic bases, gluten, or synthetic sweeteners.

How It Works ?
To understand how remineralizing gum works, you need to know a bit about the demineralization-remineralization cycle. Throughout the day, your mouth experiences acid attacks—whether from sugary snacks, coffee, or even healthy foods like fruit. These acids weaken your enamel by pulling out essential minerals.
Remineralizing gum like Underbrush combats this by:
-
Stimulating saliva, which is your body’s natural defense.
-
Providing essential minerals like hydroxyapatite, calcium, and phosphorus right to your teeth.
-
Balancing oral pH, so bacteria don’t thrive.
-
Removing soft plaque and food debris as you chew.
With regular use—especially after meals—this gum becomes a powerful tool in your oral hygiene routine.
Sustainable & Safe
One of the biggest concerns with modern chewing gum is its plastic content. Most commercial gums use synthetic rubber (often made from petroleum) as the gum base. Nathan & Sons takes a radically different approach.
We use wild-harvested tree resins as our gum base—chicle from sapodilla trees, mastic from Pistacia lentiscus, and spruce from natural forests. These resins are biodegradable, ethically sourced, and completely natural. This not only benefits your health, but also reduces your environmental footprint.
Even our packaging reflects this commitment to purity and sustainability—zero plastic, fully recyclable, and minimal waste.
