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

## Features

- 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 Mint Flavor For Fresh Breath: Cool, plant-derived mint delivers a refreshing taste while helping maintain fresh breath and oral cleanliness. Infused with xylitol, erythritol, and isolated essential oils, each chew supports a clean mouth environment without artificial sweeteners or harsh chemicals. Because we use real ingredients—not synthetics—the flavor softens over time, revealing subtle piney and herbal notes from natural resins.
- 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.

### ⭐⭐⭐ Eh... 2½ stars isn't an option.
*by J***. on January 9, 2026*

Time for my honest review. On three separate occasions I have ordered four packs of this gum. I only order it when it's on sale because frankly $44 for four packs of gum is ridiculous. First the good... My gums and teeth honestly feel better. Sensitivity has waned, and I do believe that my mouth is healthier for it. Now on to everything else. As I mentioned before I've ordered this three times and have received three different quality products. The first four pack was very heavily dusted in a powder which I assumed to be that nanohydroxyapatite. The second time I ordered it it had almost none of this and almost a completely different consistency it was crumbly and it stuck to my teeth something fierce. The last time I got it it didn't stick to my teeth but there was hardly any "dust" on the pieces. I realize that this is supposedly a handmade product however for them to vary that drastically across three different orders leaves a lot to be desired. Also worthy of noting is the gum flavor lasts about 42 seconds. I have begun looking elsewhere for my nanohydroxy appetite gum.
