## 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 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.

Review: Long lasting and pleasant! - 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!

### ⭐⭐⭐⭐⭐ Amazingggg give it a chance!
*by D***N on 19 July 2026*

I love this gum. The flavor runs out pretty quick but it’s not overwhelming and you can’t really tell it’s sugar free. The texture is off putting at first and you need to chew through it. It really does work to remineralize your teeth!! If your teeth are dirty it will stick at first but it’s doing its job: keep chewing the gum! maybe get a new piece and once you have a nice fresh mouth the gum has more durability.
