I could actually feel the difference after teeth cleanings
$30 for gum is expensive, no lie. 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.

Wonderful texture to keep the mouth busy for hours!!
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.

gum falls apart after a few minutes of use, not much flavor
I was very excited to try this game as it was available on amazon prime for a deal during prime days. Packaging is cool and came in a box with instructions that they were going to add natural xylitol in future brands and some products may be mixed. That is fine by me - however, the reason why I am giving one star is that flavor is very mild and lasts about as long as Bazooka Joe gum. If there are tooth and health benefits, it is worth it. However, the biggest issue is that the gum disintegrated and lost its ability to maintain a normal "shape" in my mouth. The gum became wrapped around my molars and I had to use a paper towel to slowly pull out pieces out of my mouth and took a long time to get it. I am not sure why or what happened to the gum and why it would fall apart so quickly - I'd say between 10-20 minutes before the gum fell completely apart but still stuck to my teeth. I don't think I'll try it again and not sure if I will finish the two small boxes I have.

Crumbles in mouth.
I think the product is decent. If it truly does help with demineralization that’s great! I do notice that my teeth don’t have that yucky feeling after chewing some. However it has basically no flavor. One pack (out of the two I opened) were funky. By funky I mean that they fell apart in my mouth and it didn’t really want to turn into gum. Like it was broke into crumbs and stayed like that. The other pack I got wasn’t that way. Makes me nervous to buy again. I think the price is a little high. But if you chew it as a I’m at work and can’t go brush my teeth but want them slightly cleaner I think it’s worth it.

I like this gum, for the most part.
I like this gum, for the most part. Taste is good, but the texture kind of throws me off. It is so dry and crumbly why you first start chewing, you have to have a lot of saliva in your mouth. All of the crumbly bits are just all over your mouth and you have to try to clump them together to get one piece. My boyfriend did not like it because of that. But once you have the pieces together it’s a nice gum. Definitely not as soft and chewy as regular gum but it’s not regular gum, it’s meant to help clean your teeth so it’s worth it. I don’t have dental insurance so I used it to try and lessen some cavities and I believe it is working. The only other thing is it loses its flavor very quickly and get a little hard to chew towards the end. I kept chewing it anyway because I wanted it to do its job. So if you have the need for it like I do, and the persistence enough to ignore the crumbly bits and reduced flavor then get it. I am by no means homeopathic in my day to day life, but when I can use homeopathic methods I try to A) because our bodies do a very good job at taking care of us and I believe natural medicine is meant to heal us and B) because it is much cheaper than modern medicine without insurance.

Amazingggg give it a chance!
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.

I was on the fence, too... Buy it!
I am very pleased with the product. I was on the fence about buying it because there was a lot of differing opinions regarding the product and the price on this productand others like it. It is expensive for gum, but I believe that they market the product very fairly, and, considering what it's made out of, I think the price is honestly very fair. Don't buy it if you're expecting to get 5 gum. The draw to this gum is that it is a healthier alternative to gums like that. Anyways, the flavor is very good, but definitely doesn't last forever. Again, if that's what you're looking for, I don't think you understand why they're making this product. The flavor in commercial gums last forever because all the chemicals and whatever else they put in it. The draw to this gum is that it doesn't have all that stuff in it. I really enjoy the texture of the gum. It's subtle, but there's something unique in the way it chews, and it's by far my favorite characteristic of the gum. As far as the remineralizing properties, I'm not qualified to say that all that is true. There may be some information out there that backs this up, I don't know. However, my teeth definitely feel very clean after chewing compared to the grainy feeling I have on my teeth from chewing other gums. So, if you're on the fence about buying this product, I would urge you to go for it. I'm definitely pleased I did. In fact, I'll be ordering another pack of the cinnamon flavor after writing this. Make sure you buy from the Nathan & Sons store. A lot of the very negative reviews I saw were under the knockoff brands of similar gum, so I'd say there is a big difference between this product and whatever the other people are putting out.

Warning: Contains ERYTHRITOL
I like the idea behind this gum, but I didn’t realize it had ERYTHRITOL when I bought it. My fault for not checking the ingredients more thoroughly but I bought it based off the video ads I received, which didn’t mention that. Last I heard, ERYTHRITOL has been linked to increase risk of blood clots/heart-attack/stroke so I don’t want to risk chewing this gum. I had one piece before I read the ingredients thoroughly and found that the flavor was fleeting. That was disappointing but I would have continued chewing it had it not been for the ERYTHRITOL. Additionally, it’s just too expensive for any average person to chew regularly. It calls for three pieces to be chewed daily. You’d burn through a box in a week at that rate and since it was ~$50 for 4 boxes that would be $600 a year to chew this gum. I’ll just stick to my remineralizing toothpaste.

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!
