Underbrush Mastic Mint Remineralizing Gum, Sugar Free Xylitol Gum with Hydroxyapatite, Supports Fresh Breath and Oral Health, Tree Sap Base, Gluten Free, No Sucralose or Aspartame, 4 Pack

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.

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

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.

I love it! It feels healthy and natural. I have ordered 2 mint and 1 berry flavor pack in the past 2 months. I prefer mint flavor to berry. The first time i tried Under Brush gum it felt slightly hard and the sweetness went in few seconds. Even though i bought it cause it says sugar free, it felt weird when the sweetness last only few seconds and I didn’t like that. I kept chewing for few minutes and I didn’t realize I am still chewing a soft bee wax like gum. The more I chew it gets softer and I love it. After Mint I bought Berry and it felt sweeter so I am back to mint which fells less sweet. My friends tried the mint they love it too. Its a little expensive so they didn’t want to buy. For me this is more like a natural medicine for my teeth health and I justify the cost based on that. Also I chew this during my work and it keeps me focused. Its feels like i am chewing beewax and some natural stuffs. I used to chew 2 gums and nowadays i like chewing just 1 even though its a very small gum size. Now, I am a regular customer because looking at ingredients it looks healthy and high quality ingredients. So I hope the company maintains the natural and high quality ingredients.

I have been a loyal fan of Nathan & Sons for about a year now, and will be for as long as they stay in business. Months before I started chewing their gum, I had to get two cavities filled. The dentist said I also had two more “almost cavities” we would have to watch. Six months later (and 2 months of Underbrush chewing later) the dentist found no problem areas in my teeth. The “almost cavities” had been reversed. Six months after that I had the quickest dental checkup ever, where the dentist informed me my teeth looked great. My teeth have never felt stronger or healthier. I’ve had no more toothaches. I absolutely LOVE that the simple act of chewing gum is helping to clean and strengthen my teeth. When I first put a piece of this gum in my mouth, I follow the clear directions on the packaging and chew in one corner of my mouth to help all the crumbling parts meld together. The initial flavor doesn’t last long, but that’s because it’s not fake flavor. There is still a pleasant taste after the initial flavor wears off. The real tree sap in the gum keeps working to clean your teeth and strengthen them as long as you chew it. Between chewing this gum and flossing, I don’t think I will have any more dental issues. This is what humans were meant to be chewing on…not the mushy trash that is store-bought gum. Worth every penny.

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!

Refreshing

Gum came stale and hard - Never order from this seller - flavour only lasts a minute. I have had this gum in the past and really enjoyed but this time it was terrible and I can't even return it!! Beware

Started out ok, but really is just too expensive for what it is… wont be buying again, maybe if at 60%+ off

Tastes 10s then is horrible
