## Description

Product description Underbrush chewing gum is crafted to do more than just freshen breath—it’s designed to support a cleaner mouthfeel with every chew. We’ve combined traditional tree-based ingredients with modern functional minerals to deliver an elevated chewing experience. Our base uses Chicle, Mastic, and Spruce resin to replace synthetic plastics, giving each piece a dense, satisfying texture. During chewing, it gradually releases nano-hydroxyapatite, a bioactive form of calcium that interacts with the enamel surface to support its mineral density and structural integrity. We also include Calcium Bentonite Clay, a fine mineral powder known for its ability to help lift away surface impurities. Together, these ingredients contribute to a clean, smooth-feeling finish that complements your daily oral care routine. Sweetened with Xylitol and Erythritol, Underbrush delivers a refreshing mint flavor without added sugars or artificial sweeteners. There’s no aspartame, no sucralose, and no plastic fillers—just a thoughtfully composed gum you can chew with confidence. How to Enjoy Your Underbrush Gum: 1. Take 1–2 pieces after meals or whenever you want to refresh your mouth. 2. Chew for at least 30 minutes to allow the mineral ingredients to fully disperse. 3. Use daily as part of your oral care routine. Ingredients XYLITOL, ERYTHRITOL, CHICLE GUM, MASTIC GUM, SPRUCE GUM P.when('A').execute(function(A) { A.on('a:expander:toggle_description:toggle:collapse', function(data) { window.scroll(0, data.expander.$expander[0].offsetTop-100); }); }); Directions Chew 1 gum after meals or once a day to support fresh breath and enamel care. For best results, use it consistently as part of your regular oral hygiene routine. See more

Review: 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: This is the real deal. Expensive, but probably worth it. As others note, the initial flavour disappears quickly, but you can chew for hours which is great for mewing and dental health in general. If I take the gum out to eat or drink something, when I pop it back in, there is a pleasant but subtle flavor. I've only chewed two or three pieces, but my teeth feel better already! Thank you Nathan & Sons!
