There’s more to enamel than fluoride.

Coffee, wine and citrus lower the pH on your enamel after every sip. Chewing gets your saliva moving, and saliva is what carries minerals back to your teeth between brushings. One piece after, and the nano-hydroxyapatite goes along for the ride. No new routine.

Only 2 of 8 gum brands publish their hydroxyapatite dose. We’re one of them: 5.7 mg per piece, in the open database.

The mechanism

How enamel actually gets its minerals back.

01

What fluoride does

Fluoride makes the enamel surface more resistant to acid and helps it take up minerals from your saliva. It is the backbone of everyday care, and nothing here is a reason to stop using it.

02

Where acid comes in

Coffee, wine and citrus drop the pH in your mouth below 5.5 for a while after each sip. Saliva slowly brings it back up. That swing happens between brushings, every day, for most of us.

03

What nano-hydroxyapatite adds

Chewing makes more saliva, and saliva is what moves minerals onto the tooth surface. Nano-hydroxyapatite is the same mineral family your enamel is built from, so it goes along for the ride. A different route from fluoride, meant to sit alongside it, not replace it.

Nano-hydroxyapatite has been used clinically in Japan since 1980. That is more than four decades.

Behind Minvelle

Started by a 20-year-old who couldn’t find a product that told the truth.

I’m Max. I started Minvelle because every oral care product I tried either overpromised or quietly made things worse.

Whitening strips that thin your enamel while claiming to fix it. Mouthwash that masks bacteria for an hour then leaves. And nobody talking about the hours between brushings.

So I spent a long time reading the research and found nano-hydroxyapatite. The same mineral family your enamel is built from, studied in Japan since 1980. Nobody in Europe was putting it in a gum.

So we brought it into one. One piece after coffee, and your saliva does the rest.

Questions, answered

Before you ask, the honest version.

How do I use it?
One piece after coffee, lunch or anything acidic, chewed for about fifteen minutes. That is the whole routine. A box holds 18 pieces, one a day, so it lasts about two and a half weeks.
Does it replace brushing or fluoride?
No, and we will not pretend otherwise. Fluoride toothpaste is the backbone of daily care. Minvelle works between brushings, through your saliva, alongside your normal routine, not instead of it.
What is actually in it?
Fourteen ingredients, each with a job: nano-hydroxyapatite, xylitol, erythritol, mastic gum, a plant-derived gum base from spruce and chicle softened with coconut oil, and natural spearmint. The full list with exact doses is published on our transparency page. Contains egg, so it is not vegan. Sugar-free and gluten-free.
Will it whiten my teeth?
It gently lifts surface stains over time. It does not bleach, and we will not tell you it does. If you want a fast, dramatic colour change, bleaching is the honest answer, not gum.
When will I notice something?
This is gradual, not overnight. Use it daily and give it a few weeks before you judge it. Some people notice sooner than others, and plenty notice nothing for a while. A quick-result promise would not be honest, so we are not making one. There is a 30-day money-back guarantee either way.
How does shipping work?
Free shipping on orders over €29, so 2 boxes and up ship free. A single box ships for €3.99. Delivery typically takes around 10 business days.
How does the subscription work?
2 boxes every 4 weeks for €32.99, which works out to €16.50 per box with free shipping. Pause or cancel anytime, no lock-in, no hoops.

If you want to do something about it, this is what we make.

One piece after coffee or food. Your saliva does the rest between brushings. 30-day money-back if it is not for you.
