How does it work?
How does it work?
When chewing, your saliva distributes nano-hydroxyapatite directly into the micropores of your enamel – exactly where cavities form.
Mastic resin and propolis simultaneously kill cavity-causing bacteria.
After 7 days: Smoother teeth.
After 14 days: Less sensitivity.
After 30 days: Denser enamel. No new cavities.

Why Remineralize?
Acids attack your tooth enamel every day.
First Signs: Sensitivity, white spots, dull shine.
If left untreated, this can lead to cavities (irreversible).
Nutryven works before it gets that far.
How Your Underbrush Is Made
Handcrafted in small batches with nano-hydroxyapatite, biomastix resin from the trees of Chios, propolis from the beehive, spruce resin from the forest, and xylitol from birch bark.

-
Teeth Feel Noticeably Smoother
The little brown spots in my grooves have bothered me for a while. Brushing and flossing helped keep them clean, but really didn’t change much. For the past few weeks, I’ve been chewing Nutryven after meals, especially after coffee. The first thing I noticed: my teeth feel much smoother and my mouth feels fresher for longer. I now always have a pack with me.
-
No Longer So Sensitive!
I constantly had sensitive teeth with cold drinks. My dentist said my enamel was partially demineralized. Since I started chewing Nutryven regularly, my teeth feel much less sensitive.
-
Finally Less Sensitive Teeth
Cold water or ice was always uncomfortable for me. This typical sensitivity was really annoying. I tried Nutryven out of curiosity because the idea of minerals in the gum sounded interesting. After some time, my enamel actually feels stronger and my sensitivity has decreased significantly.
-
Great!
I often felt a pulling sensation in my teeth, especially with cold water. My dentist said it was due to early demineralization. After a few weeks of using Nutryven, my teeth feel much stronger.
-
Teeth Remineralized
My teeth have always been sensitive to cold or sweet things. At the dentist, it turned out my enamel was worn down. I now chew Nutryven daily after meals and can really feel the difference.
-
Perfect After Coffee or Meals
After lunch or coffee, I always felt the need to chew a gum immediately. Normal gums didn’t really help beyond taste. Nutryven feels completely different. My teeth feel smoother and cleaner, and my breath stays fresh for longer. I chew it daily now.
-
Much More Comfortable After Meals
After eating, my teeth often felt rough or strange, especially after coffee or sweets. I never thought much of it, but the sensation was always there. Since chewing Nutryven after meals, my teeth feel instantly smoother and cleaner. It’s a small thing, but it makes a real difference in everyday life.
-
Finally Calm at the Dentist
In my family, cavities were a common problem, so I wanted to pay more attention. I already had a few spots and didn’t want them to keep recurring. Since using Nutryven regularly after meals, I’ve had nothing negative from the dentist. No new spots, no comments like before. Honestly, it gives me a much better feeling. It’s now become a regular part of my routine.
-
Teeth Feel Stronger
I noticed my gums becoming more sensitive in some areas. It wasn’t extreme, but slightly uncomfortable. My dentist advised me to take more care of my enamel. Brushing alone didn’t make a big difference. Since I started using Nutryven regularly, my teeth feel stronger and the pulling sensation is much less noticeable. It’s not magical, but you can tell it helps.
