"I Finally Stopped Worrying About My Breath"

"I was the guy who stood a little too far back in conversations. Covered my mouth when I laughed. Popped mints before getting close to anyone. After two weeks of chewing this after meals, my girlfriend said 'your breath has been really good lately.' I don't think about it anymore. I lean in when I talk. This gum gave me my confidence back."

"For Anyone Terrified of the Dentist—Read This"

"I hadn't been to the dentist in 4 years. The guilt was eating at me, but the fear was worse. I could feel my teeth getting worse every month. Started chewing this after meals and within weeks my teeth felt smoother, less sensitive. Having something I could actually DO every day gave me back control. I finally made that appointment—and my dentist asked what I'd been doing differently."

"The Afternoon Brush I've Always Needed"

"By 3pm my mouth felt disgusting. Coffee breath, film on my teeth, no way to brush at my desk. Regular gum helped for maybe 10 minutes. This is different—after 20 minutes of chewing, my teeth feel like I actually brushed them. I keep a pack at my desk and one in my bag. My coworkers think I'm just a gum person. They don't know I'm basically brushing my teeth."

"Whiter Teeth Without the Pain—Finally"

"Whitening strips made my teeth white for a week, then left me with shooting pain every time I drank something cold. I'd given up. Wasn't even buying this for whitening—but after a month, my coffee stains started fading. And NO sensitivity. If anything, less than before. Naturally whiter teeth AND I can eat ice cream again. I tell everyone about this."

Rebuilds Enamel While You Chew

Delivers nano-hydroxyapatite—the exact mineral your teeth are made of—directly to your enamel for 30+ minutes per piece. Unlike toothpaste that rinses away in seconds, this gives minerals time to actually bond with your teeth and fill microscopic damage.

Fights Bacteria Between Brushings

Xylitol and mastic gum work together to starve harmful bacteria and prevent plaque buildup after every meal. Chew after eating to neutralize acids, remove particles, and keep your mouth clean when brushing isn't an option.

Fresher Breath That Actually Lasts

Most gum just masks bad breath for minutes. This one attacks the source—killing odor-causing bacteria instead of covering them up. Experience breath that stays fresh for hours, not minutes.

13 Clinically-Studied Ingredients

Every ingredient serves a purpose. No fillers. No plastic polymers. No artificial sweeteners. Just clean, functional oral care.

1. Nano-Hydroxyapatite
The exact mineral your tooth enamel is made of. Bonds directly to teeth to fill microscopic damage and rebuild weakened enamel.

2. Xylitol
Natural sweetener that starves cavity-causing bacteria and increases saliva production for a cleaner mouth.

3. Erythritol
Works with xylitol to inhibit bacterial growth. Studies show it's even more effective than xylitol alone at reducing plaque.

4. Chicle Gum
Natural tree resin from Mexican sapodilla trees. The original chewing gum base—used for thousands of years. Zero plastic.

5. Mastic Gum
Greek resin with powerful antibacterial properties. Fights gum inflammation and reduces harmful oral bacteria.

6. Spruce Gum
Traditional Nordic tree resin with natural antimicrobial compounds. Supports gum health and wound healing.

7. Acacia Gum
Prebiotic fiber that supports healthy oral microbiome balance. Gentle on teeth and gums.

8. Myrrh Gum
Ancient resin with anti-inflammatory and anti-plaque properties. Used for centuries in traditional oral care.

9. Spearmint Oil
Natural essential oil for fresh breath and mild antibacterial benefits. No artificial flavors.

10. Calcium Bentonite Clay
Gently polishes teeth, binds toxins, and provides trace minerals. Helps remove surface stains naturally.

11. Calcium Carbonate
Natural mineral that supports enamel strength and provides gentle cleaning action.

12. Magnesium Carbonate
Essential mineral that works synergistically with calcium for stronger, healthier enamel.

13. Zinc Gluconate
Fights bad breath at the source by neutralizing sulfur compounds. Supports healthy gum tissue.

Rebuild your teeth

This is the first remineralizing gum engineered for oral health, using nano-hydroxyapatite and natural tree resins to rebuild enamel between brushings without plastic, artificial sweeteners, or harsh chemicals. It works by delivering minerals directly to your teeth for 30+ minutes, helping to prevent cavities before they start. Featuring 13 clinically-studied ingredients and a plastic-free gum base, this is the clean, science-backed solution you need to protect your smile.

Enamel That Gets Stronger With Every Chew

Nano-hydroxyapatite—the exact mineral your teeth are made of—bonds directly to enamel for 30+ minutes per piece. Unlike toothpaste that rinses away in seconds, this gives minerals time to actually rebuild weak spots and fill microscopic damage.

Stops Cavities Before They Start

Use it after meals and coffee. Xylitol and mastic gum starve harmful bacteria and neutralize acids that attack your enamel. Chew when brushing isn't an option to keep your mouth clean and protected all day long.

People thought gum couldn’t actually improve their teeth…until they tried it

See what 30–60 days of daily chewing can do for your enamel, breath, and confidence. It’s not magic — but it feels like the first gum that actually helps your mouth instead of just masking problems.

“Cold drinks don’t scare me anymore.”

“My teeth were so sensitive that even sparkling water hurt. I didn’t expect a gum to fix that, but here we are. After a few weeks, that sharp sting started fading. Now I can drink cold water straight from the fridge without bracing myself. It feels like my teeth finally have some armor again.”

jonas keller, germany

AGE: 41

“I’m a smoker — and my mouth doesn’t taste like an ashtray all day.”

“I know smoking is rough on my teeth and breath, and I was honestly embarrassed getting close to people. This gum doesn’t ‘hide’ the taste for five minutes like the cheap stuff — it actually cuts through it. After a cigarette I chew one piece and my mouth feels fresh, not coated. My partner even commented that I don’t smell like smoke when we’re talking face to face anymore. That alone is worth it for me.”

mira vogel, germany

AGE: 32

“My dentist noticed before I did.”

“I started chewing this after meals because it was an easy habit. At my next checkup, my dentist asked what I’d changed — there was less plaque and the ‘watch spots’ on my enamel looked better. Realizing a tiny daily thing like gum could do that made me feel like I finally have some control over my teeth instead of just waiting for the next bad news.”

anna weiss, germany

AGE: 29

“For the first time, I’m not self‑conscious about my breath at work.”

“I used to keep mints in every bag and still worried people could smell my coffee breath. After a month of chewing this after lunch, my mouth just feels clean. I’m not constantly reaching for gum anymore, and I don’t cover my mouth when I laugh. It sounds small, but it changed how I show up around other people.”

Frequently asked questions

1. Can this replace brushing or my regular dental care?

No. Underbrush is designed to support your routine, not replace it. You should still brush, floss, and see your dentist regularly—this gum protects your teeth between brushings.

2. How soon will I notice a difference?

Most people feel a cleaner mouth and smoother teeth within the first few days. Sensitivity relief and visible enamel/whitening changes usually appear after 2–3 weeks of daily use.

3. Is it safe for daily use?

Yes. It’s sugar‑free, plastic‑free, and made with 13 clinically‑studied ingredients. You can safely chew 2–4 pieces per day as part of your normal routine.

4. Can it really help remineralize enamel?

Nano‑hydroxyapatite is the same mineral your enamel is made of. Chewing keeps it on your teeth for 20–30 minutes, giving it time to bind to weak spots and support natural remineralization.

5. Will it help with bad breath?

Yes. Xylitol, erythritol, zinc, and natural mint work together to target odor‑causing bacteria, not just cover them up. Most customers notice fresher breath that lasts far beyond the flavor.

6. Is it okay for sensitive teeth?

That’s one of the main reasons people use it. The mineral blend is designed to strengthen enamel and calm sensitivity over time, without harsh whitening chemicals or acids.

7. Is it suitable for kids and teens?

Yes, when chewed responsibly. There’s no sugar, no aspartame, and no plastic base. As with any gum, only give it to children who are old enough to chew safely without swallowing.

8. What if I don’t like the taste or don’t see results?

We offer a 30‑day satisfaction guarantee. If you’re not happy for any reason—taste, texture, or results—just contact us within 30 days of delivery and we’ll make it right.
