Sugar-free chewing gum with nano-hydroxyapatite. Not a medicine, and not a replacement for brushing with fluoride toothpaste or dental check-ups.

What happens after coffee, and where a gum fits.

Acid first.
Coffee, wine, citrus and most meals lower the pH on your enamel for a while. Saliva brings it back up, slowly.
Chewing speeds that up.
Sugar-free chewing gum contributes to the maintenance of tooth mineralization, when you chew for at least 20 minutes after eating or drinking.
The mineral comes along.
Each piece carries 5.7 mg nano-hydroxyapatite, the same mineral family your enamel is built from, used in Japanese toothpaste since 1980.

Keep brushing twice a day with fluoride toothpaste. Minvelle is for after coffee and meals, not instead of brushing.

In customers' own words

Quoted with permission. First name and country only.

“I chose Minvelle because of their attention to detail and clear dosage information—I wanted a company I could trust. I use it every day after lunch, and the taste is refreshing without being overly pepperminty like ordinary gums.”

Melissa, United StatesSubscriber since September

“I was in the market for remineralizing gums and your attitude convinced me to give it a go.”

Michele, ItalyOne-time order, August

“The flavor doesn’t last long but i don’t really mind.”

Cédric, BelgiumTwo orders, August

“Your product is very good to a high degree, the only thing I'd like to be different is that it be without mint/menthol [...]”

Honest expectations

What it does, and what it will not do.

Today
Sweet first, then mint. The flavour fades before the 20 minutes are up. The chewing still counts, so keep going.
Every day after
Chewed after coffee or tea, it helps lift fresh surface stain. It never changes the shade of your teeth. The habit matters more than any single piece.
What it will not do
It will not replace brushing, fluoride or your dentist. It has not been through a clinical trial of its own. What we can show is the dose, the documents and the EU-authorised chewing claim. It is a sugar-free chewing gum, not a medicine.

Gum, strips, toothpaste. Different jobs.

Whitening strips
Fast, visible colour change by bleaching. If that is what you want, strips are the honest answer, not gum.
Fluoride toothpaste
The backbone. Twice a day, it does the main work. Keep it.
Regular sugar-free gum
Gets saliva moving after a meal. Same chewing benefit, no mineral in it.
Minvelle
Sugar-free gum with 5.7 mg nano-hydroxyapatite per piece, for after coffee and meals. Dose and documents published.

Behind Minvelle

Max

Founder, Minvelle · Austria

I started Minvelle because every oral care product I tried either overpromised or quietly made things worse. So we put the mineral enamel is built from into a gum, printed the dose on the box, and published the lab reports. One piece after coffee. Your saliva does the rest.

Questions, answered.

How does the subscription work, and how do I skip or cancel?

2 boxes every 4 or 6 weeks for €29.99, free shipping. The first renewal is 4 weeks after your order, then every 4 weeks until you cancel. Skip, pause or cancel anytime from your account (Account → Subscriptions), or email max@minvelle.com and it is done the same day. No minimum term.

How long does delivery take?

Tracked delivery in 9 to 15 business days from dispatch. You get the tracking link by email. If nothing has arrived after that, email max@minvelle.com and we sort it out.

How do I use it?

One piece after coffee, lunch or anything acidic, chewed for at least 20 minutes. A box holds 18 pieces, one a day, so it lasts 18 days.

What does it taste like?

Sweet first, then spearmint. The flavour fades before the 20 minutes are up, the chewing still counts. The texture is firmer than supermarket gum.

What is in it, and is it vegan?

Will it whiten my teeth?

Minvelle is a whitening gum in the surface-stain sense: chewing after coffee or tea helps lift fresh surface stain. It never changes the shade of your teeth. If you want a fast, dramatic colour change, bleaching is the honest answer, not gum.

Where is it made?

Minvelle is an Austrian brand, manufactured in our certified partner facility in China. Every batch is tested by an independent lab and the reports are published on the transparency page.

What if I change my mind?

30-day refund on unopened boxes. Order two, chew the first, the second stays refundable while you decide. EU customers also have the EU 14-day right of withdrawal.
