"Overall a great gum. I personally found myself able to chew for atleast 30 minutes to an hour without thinking. However the honeybun flavor and the cinnamon flavor leaves a slight bitterness to the taste, this isn't as much of a problem but its something to notice. The mint and berry flavors have got to be far better imo. Yet Overall a solid choice even regarding the price."
"New coating (to maintain product in warm environments) is attractive and effective at reducing/eliminating dissolution in hot environments (summer cars and window areas!) Gum is a bit softer on first chew, the coating is not noticed in the mouth, and the gum possibly has a sweeter first taste. Thank you for the enhanced product!"
"Love this gum! My teeth look whiter which blew my mind. My teeth feel smoother. I had a tongue ring when I was younger and it made my teeth rigid on the bottoms and when I chew this they feel smooth and strong. I tried this because a friend gave it to me, once I tried it I was mind blown. It’s a true game changer. I can say with certainty that this is an outstanding product! So happy to have found it."
"I love this gum! I didn’t chew gum for 25 years but Underbrush Gum ads made me want to try their gum. Especially because of the health benefits! I have noticed less sensitivity in my gums and teeth and jawline in general after chewing their gum for a while. My mouth feels healthier and stronger and even though the flavor doesn’t last super long the texture of the gum is really great. I have no problem chewing each piece for an hour or more. 3 pieces a day? I sometimes have 4. Once in a while I experiment and try multiple flavors together. I call eating all 4 the Cinna-Mint-Berry-Bun flavor. I love all the flavors and can’t wait to try the guava flavor!"
"I love unique items and this gum case is very unique. It is beautifully made and I love the design. So easy to use, just slide the lid and access the gum."
"It's good, but it recently changed. This order the gum texture was different out of the box, it had a shell of sweetener which it didn't have on previous boxes. After chewing it had similar texture, but it didn't have the same firmness. I understand progress in formulation, but I preferred the previous version."
"As mentioned in the instructions, it's best to warm it in your mouth for a few seconds before beginning to chew. If chewed cold, it shatters. Named flavor is relatively brief, but the flavor of the gum base is subtle and pleasant. One piece is small, but chewable. It also brought the pH of my mouth from acidic to neutral after eating. Overall, quite satisfactory. Do not leave in a hot car!"
"The gum is different at first but the flavor and texture is amazing. The gum after chewed down doesn't get hard like other brands of gum. Customer service is on point. Because the customer service is spot on I will definitely continue to shop with Nathan & sons."
"I like this flavor more than I thought I would. I love the new protective coating. I have not noticed any changes in my tooth integrity or color yet after a month of use. Good flavor, but is gone after a few minutes of chewing. Easy 5 star if I start seeing whitening."
"For reference I bought the mint flavor. I love how much better for me and the environment this gum is! I feel a lot better about using it consistently than I do using your typical chewing gum. The flavor doesn't stick around very long, which was a little disappointing considering that the first 30 seconds tasted really good, but ultimately I chew gum to keep my mouth busy so flavor isn't a huge factor for me. Also be careful when opening them for the first time! I accidentally spilled half of my pack on the floor (5 second rule was applied). The texture is also different from most chewing gums I've tried in the past. It is a much firmer chew, which I personally love! I absolutely would recommend :)"
