Underbrush Cinna-Mastic 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

Small but satisfying and seemingly helpful. I like that the gum starts as a little hard, then becomes a standard gum texture, but that gum texture doesn't turn nasty rubbery like traditional gums do. The flavor does not last long, but the neutral chewing flavor doesnt get gross So even flavorless, it feels useful to keep chewing on for teeth health. I am treating this more as a dental supplement versus a thing to chew on from boredom or to freshen my breath after a meal. It's definitely more suitable for those that are more mindful of its effects and prioritize that. I have tried the cinnamon so far. And will be ordering the mint next.

my favorite gum. very strong initial cinnamon taste. taste goes away after a few minutes but the chewiness lasts for hours. needs 2-3 pieces to enjoy the chew. breath and teeth feel great too. bit pricey but the ingredients speak for themselves. no fake sugar either which the gastroenterologist approved.

I think it’s great. Nathan made a an all natural gun. For this, I would leave a five star review however there’s some shenanigans going on let me explain: …. pricing your product by the piece and you make the piece the size of a Pea. …. I don’t think that’s cool. At least make a decent size piece , charge more and give it more accurate representation of price per piece. no matter what the cost is. Even if it cost you a lot to make, charge more accordingly, but don’t give people , a piece of gum for a baby tell them there’s 18 pieces in a box because there is not….at least not for an adult human. Maybe for a infant. Or change the label, 18 Tamarin size pieces or 6 adult size pieces. Other than that , the flavor lasts approximately 10-20 seconds, but as long as its actually remineralizing, I can live with that.

they sent me the wrong flavor. ordered cinnamon and received the mint, it took a bit to come in so i decided to try the mint anyways. it seemed like it was crumbling in my mouth at first, but the shards quickly started to harden into a thick gum. it seemed like it would stick to my teeth, but it maintains a thick gummy consistency, almost like a wax, exactly what i expected of the ingredients. its unique, and while i can't say its good for bubble blowing, it will give your jaw a workout. just one piece isn't much, but two pieces will put you to work. the flavor disappears quickly, but still seems vaguely minty even after a while. it gets almost bitter but i imagine that's the taste of the resin and etc. the longer you chew. i don't really like chewing gum, but if i notice it starting to make a difference in my dental health i will continue to use it. my dentist didn't know anything about this gum, but seemed to approve.

This gum gets 3 stars overall since it has clean, health-focused ingredients and nano-hydroxyapatite for tooth remineralization, but the initial crumbly texture, basic flavor, and steep cost make it hard to justify. Nano hydroxyapatite (nHAp) is a mineral form that your body can use to build/repair tooth enamel. People would typically chew this type of gum to also act as an antiplaque agent, reduce halitosis (bad breath), and stimulate saliva production, which helps neutralize acids and protect tooth enamel. The current trend is to chew harder/tougher gums to enhance your jawline or tone your face. This specific gum is marketed for those seeking natural, non-GMO chewing without artificial sweeteners, fitting into routines focused on holistic dental care. Keep it in a cool, dry spot to maintain freshness, and know that natural gums can harden over time. This gum comes with 18 pieces in each pack, flavored with Ceylon cinnamon and natural terpenes like eugenol, humulene, and cinnamaldehyde, using a base of chicle, mastic, spruce, myrrh, and acacia gums for a natural chew that's free of gluten, soy, seed oils, synthetic rubbers, plastics, aspartame, sugar, sucralose, or GMOs—which all seemed to align with my search for a tougher, mastic-style gum that still had decent taste but offered extra health upsides. For sweetness they’re using xylitol, erythritol, and stevia extract and for remineralizing agents they have nano-hydroxyapatite, calcium bentonite clay, and egg-shell powder. When you first pop the gum into your mouth, it’s going to fall apart into tiny chunks that will spill into the various corners of your mouth. If you weren’t expecting that, you might just spit it into the trash and return it – BUT if you have a little patience and use your tongue to start bringing those little clumps together while chewing, they will eventually form into one piece of gum again. It's important to note that it doesn't stick to your teeth initially like some other gums. The flavor (I picked was cinnamon) is pleasant, but it wasn’t very bold. When choosing gum, obviously it’s going to be healthy – but the main things that I’m looking for are going to be texture and flavor and both of those were a let down right out of the gate. Don’t get me wrong, the gum is sweet and the flavor is okay – it’s not disgusting at all … but it’s just ‘meh’ – it doesn’t stand out. What I appreciate most is the avoidance of junky additives, sticking to natural gums and sweeteners that skip the usual suspects like synthetic plastics or harmful chemicals, making it a cleaner option for oral health enthusiasts. The inclusion of quality nano-hydroxyapatite stands out, potentially aiding in tooth strengthening without fluoride, and the absence of seed oils, gluten, soy, or GMOs adds to its appeal for sensitive diets. I will caution you on xylitol though – a 2024 study suggest that higher levels of the sugar alcohol xylitol (in the blood) could be linked with an increased risk of major adverse cardiovascular events (MACE), including heart attack and stroke. I use xylitol, because the oral health benefits are amazing – but I just swish xylitol crystals for a minute and spit it out. I don’t regularly chew gums or mints like this where I would be consuming xylitol daily. Calcium bentonite clay can also have high levels of heavy metals in it, but I’ll just assume they get it from one of the safer sources. Terpenes such as eugenol and cinnamaldehyde could irritate mouths or trigger allergies in some folks, but it didn’t have any negative effects for me. I’ve already discussed the texture starting off disappointing, disintegrating into bits before gelling into a cohesive piece, which disrupts the initial chew experience. Flavor-wise, the cinnamon is underwhelming and subtle at best, not delivering a strong kick that you might be expecting. I paid $42.79 (with taxes) for what boils down to a premium but disappointing chew—the price is likely just inflated by the cost of nano-hydroxyapatite and natural sourcing—but it doesn't quite feel worth it. Outstanding ingredients, subpar texture and taste, and it’s definitely not one of the ‘tougher’ mastic chews – it’s pretty soft. This suits folks prioritizing natural dental aids, like those avoiding chemicals for cavity prevention or gum health, who don't mind paying up for non-toxic formulas and prefer mild flavors. If you're after a thoughtful, eco-friendly chew with potential enamel perks, it might be worth trying a single pack, but look elsewhere if budget or a strong taste is key. My underbrush gum cost me 59 cents a piece (they're pretty small pieces at that), you could still get some oral health benefit with something like “Zellie's” Xylitol Chewing Gum (though it doesn’t have all these bells and whistles) at 10 cents a piece.

Pretty pricey honestly but I’d rather pay more than chew on plastic regular gum. My kids say it tastes like carrots. It’s pretty sticky but they like it.

I really, really, really wanted to like this product. I tried. I cannot, in any good conscious say I would buy this product again. The flavor is good that is why I gave it a second star. However, the flavor is gone withing a very short time, honestly no more than ten minutes. The pieces are quite small. This neither adds, nor detracts. Although it can sometimes make it hard to keep the gum where you want it so you can chew it. I don't doubt the cost of supplies, but $10.00 a pack for 18 pieces breaks down to $0.56 per piece. The texture goes through a few phases, When you first bite in it is grainy, no doubt due to the natural supplies used to make it. Then once the gum "forms" it becomes rather hard to chew. Eventually is becomes softer to chew, but by then the flavor is pretty much gone. Honestly if it was returnable for a refund I would send it back,

Great gum, like nothing you’ve ever tried. It lasts for hours easily, and the taste and texture are excellent.

I really like this gum, Im on my second order. I just wish the price was lower...but my teeth feel clean and great. Sensitivity is gone. It chews the same long after the flavor is gone

Loved this item will be ordering it again

The immediate flavor is quite good, but it fades in a minute or less. I can't comment on the dental health stuff because I don't know enough about it. Holds its texture well as long as you chew it constantly. I've had a piece from 7:30AM to 5PM with no issues. If you take a break from chewing, it can lose its texture.

Love this gum but I only noticed that there's eggshell in it after I bought it. I will get one without eggshell next time.
