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. 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CTNK1ZQC | | ASIN | B0CTNK1ZQC | | Age Range Description | Adults | | Allergen Information | Dairy Free, Gluten Free, Nut Free, Soy Free | | Best Sellers Rank | #3,573 in Grocery & Gourmet Food ( See Top 100 in Grocery & Gourmet Food ) #62 in Chewing Gum | | Brand Name | Nathan & Sons | | Color | Teal | | Container Type | Packet | | Customer Reviews | 3.7 3.7 out of 5 stars (1,493) | | Diet Type | Gluten Free, Keto, Paleo, Vegan, Vegetarian | | Flavor | Mint | | Item Form | Tablet | | Item Package Quantity | 1 | | Item Package Weight | 0.19 Kilograms | | Manufacturer | Nathan & Sons | | Manufacturer | Nathan & Sons | | Number of Items | 4 | | Number of Pieces | 18 | | Package Dimensions | 5.59 x 5.16 x 1.02 inches; 6.74 ounces | | Region of Origin | United States (Handcrafted) | | Size | 18 Count (Pack of 4) | | Specialty | GMO Free, No Artificial Flavors, No Artificial Preservatives, No Synthetic Rubbers, Plastic Free | | UPC | 860010482513 | | UPC | 860010482513 | | Unit Count | 72 Count | | Units | 72 Count | ## Product Details - **Brand:** Nathan & Sons - **Color:** Teal - **Flavor:** Mint - **Package Information:** Packet - **Unit Count:** 72 Count ## Images ![Underbrush Mastic Mint Remineralizing Natural Gum, Sugar Free Xylitol Gum with Hydroxyapatite, Supports Fresh Breath and Oral Health, Tree Sap Base, Gluten Free, No Sucralose or Aspartame, 4 Pack - Image 1](https://m.media-amazon.com/images/I/71Zh3bKGplL.jpg) ## Available Options This product comes in different **Size, Flavor** options. ## Questions & Answers **Q: What does the Mastic Mint gum taste like?** A: Customers love the fresh, crisp flavor of this gum.

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 ### ⭐⭐⭐⭐⭐ Good quality gum, no nasty chemical taste after hours of chewing. *by A***N on April 14, 2026* Product is as advertised, I chewed a couple peices for like 6 hours, ofc it loses its flavor fast but what gum doesn’t, however, I don’t get a weird toxic taste in my mouth after only 30 minutes of chewing like most other gums, as well as my teeth feeling really smooth in the parts I chewed with. It won’t reach the outside of your teeth too well but that’s the nature of chewing gum, I still think this helps your teeth remineralize it just really helps the inner parts of your teeth where all the crushing goes. ## Frequently Bought Together - Nathan and Sons - Underbrush Gum - Sugarless Gum with Nano Hydroxyapatite for Fresh Breath and Enamel Care - Pack of 4 - Boka Fluoride Free Toothpaste Nano Hydroxyapatite, Helps Remineralize, Appropriate for Sensitive Teeth, Whitening - for Adult, Kids Oral Care - Ela Mint Flavor, 4 Fl Oz 1Pk US Manufactured - PUR Gum | Aspartame Free Chewing Gum | 100% Xylitol | Natural Spearmint Flavored Gum, 55 Pieces (Pack of 1) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/674574121-underbrush-mastic-mint-remineralizing-natural-gum-sugar-free-xylitol-gum](https://www.desertcart.vn/products/674574121-underbrush-mastic-mint-remineralizing-natural-gum-sugar-free-xylitol-gum) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-25*
