Chew it for 30 days. No results? Full refund — even if the tins are empty.

What you'll notice

From the first piece: breath that stays fresh for hours, teeth that feel smoother and cleaner, and a smooth lift of focused energy.

Within 2-3 weeks: visibly whiter teeth, less sensitivity to cold, stronger-feeling enamel, less plaque and healthier-looking gums.

One piece of gum. Three jobs: whiter teeth, stronger enamel, fresher breath. No new habit.

How to use
  • Chew 1-2 pieces a day — after meals, with your morning coffee, or whenever you want a reset.
  • Chew each piece for 15-20 minutes. The longer it stays in your mouth, the longer the minerals work.
  • 2 packs (48 pieces) last about 3-4 weeks at 2 a day. Most people grab 4+ packs so they never run out.
  • Contains natural caffeine from guarana. Not for children under 12. Recommended 16+.
Ingredients
  • Nano-Hydroxyapatite — the mineral your enamel is made of. Fills micro-cracks and rebuilds from within.
  • Sodium Phytate & Sodium Hexametaphosphate — lift coffee, tea and wine stains without bleach.
  • Zinc Citrate & Zinc Gluconate — neutralize the sulfur compounds behind bad breath.
  • Xylitol & Erythritol — sweet taste, zero sugar; they starve cavity-causing bacteria.
  • Guarana — natural slow-release caffeine. No jitters, no crash.
  • L-Theanine — keeps the energy calm and focused.
  • Vitamin B12 — supports natural energy and brain function.

No peroxide. No sugar. No aspartame. Vegan. Gluten-free.

Is yuki right for me?

I have fillings, crowns or veneers. Yes — yuki doesn't bleach or scrub. It works with your dental work, not against it.

My teeth are sensitive. That's exactly who it's for. Nano-hydroxyapatite is studied for reducing sensitivity over time.

Do I still brush? Yes. yuki works between brushings, not instead of them.

Is it worth the price? It replaces whitening strips, mouthwash, mints and your afternoon coffee — for about $0.62 a piece.

How it works

What happens while you chew

The Japanese 4-step enamel ritual — from the first chew to all-day protection.

1
Step 1

Coats your teeth

As you chew, the minerals mix with your saliva and spread over every single tooth.

2
Step 2

Kills bad breath

The zinc complex neutralizes the odor-causing compounds on contact — at the source.

3
Step 3

Rebuilds enamel

Nano-hydroxyapatite, the mineral your teeth are made of, fills tiny gaps and makes enamel stronger.

4
Step 4

Builds a shield

Xylitol and sodium phytate help block new stains and cavity bacteria from settling in.

The Japanese secret

Japan figured this out 40 years ago.

Most Americans have never heard of hydroxyapatite. In Japan, it's been a go-to for stronger, whiter teeth for decades.

1970s

A Japanese company acquires NASA's research on hydroxyapatite — the mineral that makes up bones and teeth.

1980

Hydroxyapatite lands in Japanese toothpaste.

1993

Japan officially recognizes it as an anti-cavity ingredient.

Today

Now in a gum you chew after coffee — no new habit.

yuki brings that Japanese formula to the easiest habit there is: chewing gum.

The research

Backed by science. Not by hype.

Every active ingredient in yuki has been studied, published and used in oral care for decades. We cite the research so you can check it yourself.

Nano-Hydroxyapatite

A calcium phosphate that mirrors natural enamel. Studied to remineralize early lesions, reduce sensitivity and whiten gradually — no bleach, no abrasion.

  • Clinical trial, 2014 (J Clin Dent): hydroxyapatite gum cut tooth sensitivity by about half in 2 weeks vs. a placebo gum. View study ↗
  • In-mouth study, 2023 (J Mech Behav Biomed Mater): nano-hydroxyapatite gum raised calcium levels in enamel vs. plain gum. View study ↗

Sodium Phytate & Hexametaphosphate

Bind to the tooth surface to lift stains and stop new ones from setting — a non-peroxide way to brighten.

  • Clinical trial, 2006 (J Clin Dent): gum with sodium hexametaphosphate reduced new tooth stain by 33% over 12 weeks. View study ↗
  • Clinical trial, 2002 (J Clin Dent): sodium hexametaphosphate removed 29% more surface stain than regular toothpaste. View study ↗
  • Clinical trial, 2025 (Clin Oral Investig): sodium phytate made teeth measurably whiter in 3-4 weeks. View study ↗

Zinc Citrate & Gluconate

Neutralize the sulfur compounds that cause bad breath and slow the bacteria that make them.

  • Clinical trial, 2012 (J Clin Dent): zinc gum cut bad-breath sulfur compounds by about 51% right after chewing. View study ↗
  • Systematic review, 2017 (J Breath Res): zinc chewing gums reduced bad-breath compounds across 10 trials. View study ↗
  • Clinical trial, 2025 (Indian J Dent Res): zinc cut bad-breath compounds for over 2 hours. View study ↗

Xylitol & Erythritol

Sugar alcohols oral bacteria can't ferment, linked to less plaque and fewer cavities in long-term studies.

  • Meta-analysis, 2017 (J Nat Sci Biol Med): xylitol reduced cavities across 16 studies. View study ↗
  • Systematic review, 2024 (Eur Arch Paediatr Dent): xylitol gum significantly reduced cavities in children and teens. View study ↗
  • 3-year clinical trial, 2014 (Caries Res): erythritol led to fewer cavities than xylitol or sorbitol. View study ↗

Questions

Frequently asked questions

What does yuki actually do?

Three things at once: it rebuilds enamel with nano-hydroxyapatite, lifts coffee and wine stains with sodium phytate, and keeps your breath fresh for hours with zinc. Plus a clean lift of energy from guarana, L-theanine and B12.

Can gum really whiten teeth?

Yes. yuki uses nano-hydroxyapatite, the mineral your enamel is made of, plus sodium phytate to lift surface stains. Japan has used hydroxyapatite in oral care for over 40 years.

Is it safe with fillings, crowns or veneers?

Yes. No bleach, no abrasives.

Does it contain caffeine?

Yes, natural caffeine from guarana. Not for children under 12; recommended 16+.

When will I see results?

Fresh breath: right away. Whiter teeth: usually 2-3 weeks. Deeper stains: 4-6 weeks.

How many pieces a day?

1-2, for 15-20 minutes each. More chewing, faster results.

Do I still need to brush?

Yes. yuki works between brushings, not instead of them.

How long does shipping take?

Orders ship within 24-48 hours. Delivery takes 5-8 business days.

What if it doesn't work for me?

You're covered by our 30-day money-back guarantee. Email us and we'll refund you in full — even if the tins are empty.
