Benefits out weigh short-lived flavor
I see people giving bad review but I think their expectations come are from chewing bad gum. First off this gum isnโt for FLAVOR itโs purpose driven. This gum works wonders for me. I have a noticeable difference in gum inflammation and overall oral health with and without chewing this (I smoke cigarettes unfortunately and sometimes have gum inflammation). And I enjoy the texture personally.. Now to be critical. The gum flavor lasting 5 secs is true. The flavor bursts immediately upon biting into it and is very enjoyable. But it quickly fades into the background of the natural flavor of the gum. (Which is best describes earthy). I personally enjoy the flavor of the gum itself, but the mint flavor is short lived. You also cannot drink anything cold with this gum or it breaks into 1000 pieces. Itโs pricey but to me the benefits are worth it, I chew 2-3 pieces a day so a pack last week a week or so. I chew the same piece for hours no problem.

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.

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 thatโs great! I do notice that my teeth donโt 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 didnโt really want to turn into gum. Like it was broke into crumbs and stayed like that. The other pack I got wasnโt that way. Makes me nervous to buy again. I think the price is a little high. But if you chew it as a Iโm at work and canโt go brush my teeth but want them slightly cleaner I think itโs 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 itโs a nice gum. Definitely not as soft and chewy as regular gum but itโs not regular gum, itโs meant to help clean your teeth so itโs worth it. I donโt 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.

Love it for natural ingredients and no sugar
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 didnโt like that. I kept chewing for few minutes and I didnโt 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 didnโt 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.

not like the gum you think but definitely the gum you need
I had my doubts about this but i took a chance and tried it. honestly i can say my teeth felt so much stronger and whiter. the flavor doesn't last long but that doesn't bother me too much because most other gums are so strong it makes me nauseous. it's not very sweet. if you leave it in a cold area it will be very hard but after chewing a little it softens back up

Not bad but overprice
I had very high expectations for this gum after watching several ads for it. Overall the gum is overpriced, I do value the fact that it uses real gum from trees and not a synthetic base; however it is not the brand to do so. The flavor of the gym does not last long and the pieces are small had to use several pieces to have a proper chew. The Hydroxyapatite is a nice touch but hydroxypatite toothpaste, mouthwash is a better buy that will last longer. Not bad gum but not worth the price, not much gum per box

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!
