Oral care is often seen as a two-step process: brushing and flossing. But what if there was a third step—a natural one—that actively supports your teeth throughout the day? That’s where remineralizing gum comes into play, and Nathan & Sons is leading the charge with a cleaner, smarter approach to chewing.
We created Underbrush® with a mission in mind: to reimagine gum as more than just a breath freshener. With every chew, you’re giving your enamel the minerals it needs to fight erosion, sensitivity, and decay—naturally, safely, and sustainably.
What Makes Our Gum Remineralizing?
Remineralization is the process of restoring essential minerals—like calcium and phosphate—to tooth enamel. Throughout the day, acid from food, drinks, and oral bacteria depletes these minerals, leaving enamel vulnerable. Traditional gum only masks symptoms like bad breath. But remineralizing gum helps rebuild your enamel with every chew.
Our formula is packed with nano-hydroxyapatite (the same mineral that makes up your enamel), along with supportive ingredients like eggshell powder, bentonite clay, and tree resins. Together, they encourage remineralization, reduce acid, and promote a healthier oral microbiome.
Clean Ingredients with a Clear Purpose
Nathan & Sons is committed to creating products that are not only effective but also clean and honest. Every piece of Underbrush gum is made with carefully chosen, whole-plant ingredients that work with your body—not against it.
Here’s what you’ll find in our gum:
● Nano-hydroxyapatite: Mimics natural enamel to support tooth repair.
● Wildcrafted Tree Resins: Chicle, mastic, and spruce provide the gum base—biodegradable, plastic-free, and full of plant power.
● Eggshell Powder: A sustainable source of calcium carbonate that polishes and supports remineralization.
● Calcium Bentonite Clay: Detoxifies and helps gently clean your teeth.
● Xylitol and Erythritol: Natural sweeteners that neutralize acids and starve harmful bacteria.
● Ceylon Cinnamon or Organic Mint: Natural flavors with antimicrobial properties and a refreshing taste.
All flavors are derived from nature. There’s no synthetic aftertaste, no artificial colors, and no chemicals you can’t pronounce.
The Real Impact on Your Teeth
So, what actually happens when you chew Underbrush?
● Enamel Support: Nano-hydroxyapatite begins to adhere to weak spots on your teeth, mimicking your natural enamel structure.
● Acid Neutralization: Saliva production increases, aided by xylitol, helping neutralize acid and flush out food particles.
● Plaque Disruption: Antimicrobial plant resins help reduce bacteria that contribute to plaque and gingivitis.
● Whitening Effects: Natural abrasives gently polish teeth, helping to lift stains over time.
● Fresh Breath: Essential oils and natural antiseptics eliminate odor-causing bacteria—not just mask them.
Chew after meals, after snacks, or whenever you need a reset. You’ll feel the difference right away—and over time, your smile will show it too.
Sustainable from the Source
We believe that good oral care shouldn’t come at the cost of the planet. That’s why we use only sustainably harvested tree resins from trusted sources, ensuring the environment remains healthy while your teeth do too. Our gum base is 100% plastic-free—no synthetic rubber, no microplastics, and no waste left behind.
Even our packaging reflects our values. It’s biodegradable, recyclable, and designed to leave a light footprint.
