## Description

Mineral-Rich Gum With Nano-Hydroxyapatite: Crafted with a blend of naturally derived minerals, this gum helps support enamel integrity, reduce surface buildup, and maintain oral balance. The bioavailable nano-hydroxyapatite mirrors the natural mineral composition of teeth for gentle, effective daily use that fits any clean lifestyle routine. Natural Berry Flavor For Fresh Breath: Crafted with natural berry flavor and naturally sweetened with xylitol and erythritol, this gum offers a subtly sweet, refreshing taste while helping maintain oral cleanliness. Infused with isolated essential oils, each chew supports a balanced mouth environment, free from artificial sweeteners or additives. The flavor naturally fades into gentle, resin-forward notes, offering an authentic, nature-inspired chewing experience. Hearty Tree Sap Chewing Base: Crafted from natural tree sap sourced from chicle, mastic, and spruce, this gum delivers a satisfying, full-bodied chew that feels substantial and real. The naturally resilient texture offers gentle resistance—activating minerals as you chew—for an authentic, grounding, and eco-conscious experience. Mineral-Rich With Natural Cleansing Action: Infused with calcium bentonite clay and trace minerals like calcium, iron, and zinc, this gum starts firm to help gently scrape and lift particles from teeth. As you chew, it softens into a smooth texture that supports a cleaner, more refreshed mouthfeel with every bite. Crafted In California With Globally Sourced Ingredients: Made in small batches using wild-foraged botanicals and 100% non-toxic ingredients from around the world, this gum is free from plastics, aspartame, sucralose, preservatives, and gluten. Every piece reflects a commitment to sustainability, purity, and thoughtful, planet-friendly oral wellness.

Review: Wonderful texture to keep the mouth busy for hours!! - I have ADHD and this gum lasts me the whole day as a chew toy. Its the perfect texture for this purpose. Its essentially a good flavorless mastic gum texture that you forget is there while you work. It's really good at keeping my mouth busy, I didnt intend it this way, but as a side benefit my jaw seems to look a little broader and stronger because I chew this stuff constantly. All this with the peace of mind knowing im not ingesting anything nasty. Side benefit: When I have this after meals, I make sure to move it around to all the areas where crumbs might be to keep them from just sitting there and causing damage. Like a toothpick but way more effective. The food bits will then flavor the gum as what you last ate for a minute, but dont worry it then it goes back to flavorless just by chewing. To all the people 1-star reviewing this gum for being hard to chew and fragmenting... did you READ the pamphlet? It literally says to let the gum warm in your mouth a little before biting into it. To all the people 1-star reviewing this gum for short-lasting flavor... could you THINK for a moment? You need chemicals (microscopic plastic sacs) to make flavor last unnaturally long by releasing flavor slowly overtime. This is a NATURAL gum and dosent have those. You cant have your cake and eat it too, so stop disparaging this honest company because you failed to understand what you were buying to begin with... You want a genuine natural gum, this is it.
Review: Still good - I honestly believe this gum just is a trade off. Overall good, but expensive. Pros: Healthy , Organic, Tastes good (I got mint), Good chew (more stiff), Last long (integrity, not flavour), Biggest surprise was I can eat or drink anything directly afterwards without that classic taste/cold sensation off mint, Packaging (perhaps a bit simple and overkill at the same time) Cons: Small size (chew 2 at a time), flavour falls off within minutes (stays almost subtle, keeps breathe relatively neutral), Price

### ⭐⭐⭐ First time trying
*by D***A on February 18, 2026*

Cons: Stuck to a few places in my teeth. Flavor is gone so fast. Small pieces and expensive. Pros: Love the concept and proper ingredients. Fruit tastes very nice. It doesn't get hard as it's wearing out. Starts popping letting me know time is running out. I like it. I'm retired so a pack is expensive. I stopped buy regular gum years ago and eat altoids. I'll treat myself once in a while. Hopefully price might come down as your gum gets more popular. Great job though. Everyone needs proper minerals as they age. Not plastics and rubber. 👍 😎 💯
