Scandi is built on ingredients that have been clinically tested, published in peer-reviewed journals, and used in real oral care products for decades. Every active ingredient targets a specific mechanism — and we link the studies so you can verify the science yourself.

Nano-Hydroxyapatite (nHAp)

A biocompatible calcium phosphate that mirrors natural tooth enamel. Clinically shown to remineralize early enamel lesions, reduce hypersensitivity, and support whitening — without harsh abrasives or peroxides.

Sodium Phytate & Sodium Hexametaphosphate

Chelating agents that bind to calcium ions in stains, preventing new discoloration and loosening existing chromogens. Non-abrasive, non-peroxide whitening that preserves enamel integrity.

Zinc Citrate & Zinc Gluconate

Zinc ions inhibit volatile sulfur compounds (VSCs) — the primary cause of bad breath — and reduce odor-producing bacteria for sustained freshness well beyond chewing.

Xylitol & Erythritol

Non-fermentable sugar alcohols that cannot be metabolized by oral bacteria into enamel-damaging acids. Long-term studies show reduced S. mutans levels, less plaque, and lower caries incidence.

FOR THE STRIP YOU QUIT

of people who use whitening strips experience sensitivity.

The sharp electric pain through your front teeth at 2am. The cold water you couldn't drink for two days. The box you powered through for three sessions before quietly putting it back in the drawer.

That's not a willpower problem. That's a peroxide problem.

Peroxide bleaches enamel. Bleaching opens dentinal tubules. Open tubules cause pain. That's the mechanism behind every major whitening brand you've already tried.

Lumin doesn't use peroxide. It never will.

MEET LUMIN

MEET LUMIN

A functional whitening gum. Not the whitening product you've used before — because it doesn't work the way whitening has ever worked before.

The active ingredient is nano-hydroxyapatite. It's the same calcium phosphate mineral that makes up the structure of your tooth enamel. Not a proprietary complex. Not a trend ingredient. It's been used in Japanese restorative dentistry since the 1980s. There are 80+ peer-reviewed studies behind it. You're welcome to search for them.

We're a brand that says: look it up.

Chew for 15 minutes. That's the full protocol.

Every stain lives in a micro-crack.

Coffee, wine, and tea don't sit cleanly on your enamel — they seep into the tiny fractures and demineralised patches on the surface. The more porous the enamel, the deeper the stain settles.

When you chew Lumin, nano-hydroxyapatite particles dissolve into your saliva. They migrate to those micro-cracks and bind to the damaged enamel — filling in the exact sites where staining accumulates. Over 2–3 weeks of daily use, the surface becomes smoother, denser, and structurally more resistant to future staining.

Whiter teeth. Not because anything was stripped away. Because the surface was repaired.

No peroxide. No oxidation. No open tubules. No nerve sensitivity — not because we were careful, but because the mechanism that causes sensitivity doesn't exist in this product.

FAQ

Is this actually whitening, or just toning like the purple toothpaste?

Actual whitening. Nano-hydroxyapatite physically repairs enamel — it's structural, not a colour filter. Results build over weeks of use, which is how you know something real is happening.

How long before I see results?

2–3 weeks of daily use. Not overnight — because the mechanism is structural, not cosmetic. Enamel remineralises gradually. Most people notice a visible difference within the first two weeks.

I've had really bad sensitivity from strips. Will this hurt?

No. That's not a marketing claim — it's mechanistic. Strip sensitivity comes from peroxide opening enamel tubules. Lumin contains no peroxide. The pathway that causes sensitivity does not exist in this formulation. If you've felt strip pain, you will not feel this.

I have fillings / crowns / veneers — is it safe?

Yes. Nano-hydroxyapatite is pH-neutral and biocompatible. It doesn't interact with restorations the way peroxide does. It's the ingredient used on patients who can't tolerate bleaching.

I've tried everything and nothing worked. Why would this?

Because everything you tried was trying to bleach the stain. This fills the cracks where stains live. Different mechanism, different result. If you've been solution-exhausted, that makes sense — you've been trying the wrong thing.

How often should I chew?

Once daily, 15 minutes. After your first coffee or after a meal is ideal — that's when you're already reaching for something anyway.

Is it vegan?

Yes. The nano-hydroxyapatite is synthetically produced (bio-identical) — not animal-derived. No sugar, no aspartame.
