The 20-minute window: how one piece of Minvelle nano-hydroxyapatite gum works

  1. 1Chew one piece after coffee or food. The cue is the empty cup, not a new routine.
  2. 2Chewing drives saliva flow within ~20 minutes. Xylitol has 45+ years of literature behind that.
  3. 3Saliva carries the 5.7 mg nano-hydroxyapatite in each piece of Minvelle gum to your enamel between brushings. Complement to fluoride brushing, not a replacement.

What to expect, honestly

Realistic about what gum can and cannot do

Today

A habit, not an overnight fix

One piece after coffee or a meal, at least 20 minutes. That is the whole routine.

Every day after

Gradual by design

Chewing after coffee or tea helps lift fresh surface stain, so the daily habit matters more than any single piece.

What it will not do

Support, not a procedure

It will not change your shade, replace brushing or replace your dental check-ups. That is also why you will not find a before and after photo here.

Why your teeth are getting worse

You brush twice a day but your teeth are still getting worse

It is not your fault. The stuff you use every day quietly strips enamel. And once it is gone, it does not come back. Unless you support remineralization.

Coffee, wine and citrus erode enamel daily

Every sip drops your mouth's pH below 5.5. At that level, enamel physically dissolves.

Strips bleach. Minvelle does not.

Peroxide strips change the shade by bleaching. Minvelle has no peroxide and does not bleach: it helps lift fresh surface stain and leaves your shade as it is.

Fluoride remineralizes too. This is the fluoride-free route.

Fluoride has the deepest evidence base in dentistry. Nano-hydroxyapatite is the actual mineral enamel is made of, and it supports the same process without fluoride, for people who want daily care between brushings.

80%

of US adults show erosive tooth wear in NHANES data. Most never notice it starting.

How it works

Three things happen every time you chew

01

Chew one piece a day, after the worst acid hit

Right after your morning coffee is the classic moment. Wine or a citrus-heavy lunch count too, pick the one that hits your enamel hardest. Chew for at least 20 minutes. No new step in your routine. You are already chewing gum. Now it does something.

02

5.7 mg nano-hydroxyapatite per piece

Hydroxyapatite is the mineral enamel is mostly made of. It supports enamel remineralization while you chew.

03

Chewing gets saliva moving

Sugar-free chewing gum contributes to the maintenance of tooth mineralization. The effect comes from chewing for at least 20 minutes after eating or drinking. Chewing after coffee or tea also helps lift fresh surface stain. It never changes the shade of your teeth.

What's inside

Every ingredient has a reason. Nothing filler. Nothing hidden.

Fourteen ingredients, each in for a job. Three do most of the work. The other eleven round out the formula.

Nano-Hydroxyapatite

Active ingredient in Minvelle nano-hydroxyapatite chewing gum · 5.7 mg per piece, published and batch-certified

The mineral your enamel is mostly made of. Supports enamel remineralization while you chew. Used in oral care in Japan since 1980.

Xylitol

Active ingredient in Minvelle nano-hydroxyapatite chewing gum · 817 mg per piece

Sweetens without sugar, together with erythritol. Derived from birch.

Mastic Resin

Active ingredient in Minvelle nano-hydroxyapatite chewing gum

A natural resin from the Greek island of Chios, chewed for over 2,000 years. Gives Minvelle its flavour, together with spearmint oil.

See the other 11 ingredients

The other eleven ingredients in Minvelle nano-hydroxyapatite chewing gum, alongside nano-hydroxyapatite, xylitol and Chios mastic resin.

Erythritol

Zero glycaemic impact. Works alongside xylitol to sweeten naturally, without sugar.

Chicle and Mastic Base

Plant-derived gum base: chicle and mastic, with a touch of spruce. No petroleum, no synthetic polymers. Just what the trees make naturally.

Calcium Bentonite Clay

Gently polishes the tooth surface while delivering a direct hit of calcium and magnesium to support remineralization. The mineral your enamel keeps asking for.

Egg-Shell Calcium

Bioavailable calcium from eggshell. Structurally close to the calcium in your teeth, so your body absorbs and uses it faster than many synthetic versions.

Myrrh and Acacia Gum

Two resins used in oral care for thousands of years.

Natural Spearmint Oil

Real spearmint oil, whose terpenes (menthone, carvone and cineol) carry the freshness. It actually lasts, without artificial sweeteners or flavourings.

Coconut Oil, Glyceryl Monooleate and Silica

The texture team. Coconut oil keeps the plant base soft enough to chew, glyceryl monooleate keeps the mix even, and a trace of silica keeps the pieces from sticking together in the box.

Gum or toothpaste? Both, at different moments.

While you brush

Your toothpaste does the heavy lifting twice a day. Keep it. If it contains fluoride or hydroxyapatite, it is already remineralizing while you brush.

Between brushings

The acid hits happen between brushes: coffee, snacks, citrus. One piece a day, chewed after your worst acid moment, delivers 5.7 mg nano-hydroxyapatite, the published, batch-certified dose we call The Documented Dose, while your enamel is still recovering. The after-coffee slot works best.

What gum can't do

Gum does not clean plaque and never replaces brushing. It covers the hours your toothbrush can't.

Questions, answered

Before you order

Does Minvelle support enamel remineralization?
Minvelle contains 5.7 mg nano-hydroxyapatite per piece, the mineral enamel is mostly made of, and it supports enamel remineralization while you chew. Sugar-free chewing gum contributes to the maintenance of tooth mineralization; the effect comes from chewing for at least 20 minutes after eating or drinking. Nano-hydroxyapatite has been used in Japanese oral care since 1980.
How often should I chew Minvelle gum?
One piece a day, after a meal or an acidic drink like coffee, wine, or citrus. Chew it for at least 20 minutes to give the active ingredients enough contact time with your teeth.
Is Minvelle safe to use long-term?
Yes. All three active ingredients (nano-hydroxyapatite, xylitol, Chios mastic resin) have decades of safety data. Nano-hydroxyapatite has been used commercially in Japan for 45+ years with no significant safety concerns, and the European Commission has reviewed and accepted it as safe for oral care products.
What's the difference between Minvelle and regular whitening gum?
Minvelle has no peroxide and does not bleach. Chewing after coffee or tea helps lift fresh surface stain, and each piece carries 5.7 mg nano-hydroxyapatite, with the dose published. It never changes the shade of your teeth.
How long does it take to see results from Minvelle?
There is no overnight result. Chewing after coffee or tea helps lift fresh surface stain, so the daily habit matters more than any single piece. It never changes the shade of your teeth.
Does Minvelle replace toothpaste or brushing?
No. Minvelle is designed to complement your existing oral care routine, not replace it. Continue brushing twice daily and flossing. Minvelle adds active remineralization in between brushing sessions, one piece a day after your most acidic meal or drink.
What's your return policy?
30-day refund on unopened boxes. If Minvelle doesn't work for you, return any unopened boxes within 30 days for a full refund. Free shipping on orders €29+.
Does whitening gum actually work?
It depends what you ask it to do. Whitening gum will not bleach your teeth a shade lighter the way a peroxide tray does. What it can do is help lift the fresh surface stain that coffee, tea and wine leave behind. Minvelle is built for exactly this: chew one piece a day, ideally right after coffee, for at least twenty minutes. One box is 18 pieces, 18 days of daily use. The daily habit matters more than any single piece.
How do I get rid of coffee stains on my teeth?
Coffee stains are surface stains: the tannins in coffee, tea and wine cling to the micro-roughness in your enamel and darken it over time. The highest-value moment to act is right after your cup, when chewing gets saliva moving and rinses loose pigments away before they bond. Chew one piece a day, ideally straight after your morning coffee, for at least twenty minutes. It helps lift fresh surface stain rather than bleaching deeper discoloration, and it never changes the shade of your teeth.
Is xylitol gum good for your teeth?
Sugar-free chewing gum contributes to the maintenance of tooth mineralization; the effect comes from chewing for at least 20 minutes after eating or drinking. Xylitol is what keeps Minvelle sugar-free: each piece carries 817 mg, together with erythritol.
Is chewing gum good or bad for your teeth?
It depends on what is in the gum. Sugar-free chewing gum contributes to the maintenance of tooth mineralization; the effect comes from chewing for at least 20 minutes after eating or drinking. Chewing also gets saliva moving, which rinses away food and loose pigments. Minvelle is sugar-free and adds 5.7 mg nano-hydroxyapatite per piece.
How does the subscription work?
Two boxes, 36 pieces, every 4 weeks for €29.99. That is €15.00 per box, €10.00 less than the same two boxes ordered once. You can skip a delivery, pause, or cancel from your account, with no minimum term. Your rate does not go up while you stay.

Any credit card and most debit cards. Some app-based banks block recurring charges on their debit cards. If a renewal fails we pause the subscription and email you a link to update the card. Nothing gets cancelled.
