## Description

Review: Benefits out weigh short-lived flavor - I see people giving bad review but I think their expectations come are from chewing bad gum. First off this gum isn’t for FLAVOR it’s purpose driven. This gum works wonders for me. I have a noticeable difference in gum inflammation and overall oral health with and without chewing this (I smoke cigarettes unfortunately and sometimes have gum inflammation). And I enjoy the texture personally.. Now to be critical. The gum flavor lasting 5 secs is true. The flavor bursts immediately upon biting into it and is very enjoyable. But it quickly fades into the background of the natural flavor of the gum. (Which is best describes earthy). I personally enjoy the flavor of the gum itself, but the mint flavor is short lived. You also cannot drink anything cold with this gum or it breaks into 1000 pieces. It’s pricey but to me the benefits are worth it, I chew 2-3 pieces a day so a pack last week a week or so. I chew the same piece for hours no problem.
Review: I could actually feel the difference after teeth cleanings - $30 for gum is expensive, no lie. But you need to remember what we are comparing this gum to - the cheap stuff is cheap for a reason, mass produced, chemicals, singularly designed for a pleasant chewing experience. I have Invisalign and maintaining the cleanliness of my teeth is very important since they are effectively sealed most of the time. I bought my first ever pack of Underbrush in early February right after a Gingevectomy and several prior cleanings to prepare for Invisalign. I would chew two pieces at a time then blob them together and keep it in a container. Yes the blob was tasteless but it was SHOCKINGLY chewable up until just yesterday when the blob finally felt like it was disintegrating. So from February to April I was able to chew this gum almost daily. I went in for an annual cleaning in March and it was a night and day difference. My tooth sensitivity was significantly decreased. My dental hygiene had improved yes, but not enough in my opinion to create such a noticeable difference. I was absolutely wincing when my teeth were getting polished or picked and after this gum it was more than tolerable. I believe this gum did help remineralize my teeth and I'm going to keep on chewing it. My recommendation is to not throw it away after each chew but basically keep it until its unchewable. This is not delicious gum, this is natural, teeth strengthening gum. It is temperature activated so a hot environment will melt it - don't keep in the car.

## 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.

### ⭐ gum falls apart after a few minutes of use, not much flavor
*by R***D on July 14, 2026*

I was very excited to try this game as it was available on amazon prime for a deal during prime days. Packaging is cool and came in a box with instructions that they were going to add natural xylitol in future brands and some products may be mixed. That is fine by me - however, the reason why I am giving one star is that flavor is very mild and lasts about as long as Bazooka Joe gum. If there are tooth and health benefits, it is worth it. However, the biggest issue is that the gum disintegrated and lost its ability to maintain a normal "shape" in my mouth. The gum became wrapped around my molars and I had to use a paper towel to slowly pull out pieces out of my mouth and took a long time to get it. I am not sure why or what happened to the gum and why it would fall apart so quickly - I'd say between 10-20 minutes before the gum fell completely apart but still stuck to my teeth. I don't think I'll try it again and not sure if I will finish the two small boxes I have.
