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.

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.
