In just 4 weeks, you can expect:
- Cleaner, smoother teeth
- Calmer gums when you brush
- No fuzzy feeling on your teeth
- A gently brighter smile
- Fresh breath that lasts
- Free from fluoride, SLS and parabens
- No morning breath
- Less plaque build-up
Our formula is built around nano-hydroxyapatite, the mineral your enamel is made of.
- It settles into the tiny cracks in your enamel and helps make it stronger.
- It leaves a mineral layer that helps protect against stains, acid and sensitivity.
- The result is brighter, stronger teeth and fresher breath, without bleach or harsh chemicals.
- Put a pea-sized amount on your brush and spread it over your teeth before you start brushing.
- Brush gently for 2 to 3 minutes so the paste reaches every surface.
- When you're done, spit and skip the rinse. The mineral stays on your teeth and keeps working for hours.
- Brush twice a day, morning and night. The night brush matters most, because the mineral works while you sleep.
Nano-hydroxyapatite. The same mineral your enamel is made of, in a form small enough to settle into tiny gaps on the surface of your teeth.
Xylitol. A natural sweetener that the bacteria behind tooth decay can't feed on.
A fresh mint flavour that doesn't burn.
What's not in it: no fluoride, no SLS and no parabens. Vegan and cruelty free.

- Regular toothpaste cleans the surface, but it doesn't give back the minerals your teeth lose every day.
- Fluoride hardens the outer layer, but it isn't what your teeth are made of. That's why fluoride toothpaste tells you not to swallow it.
- Whitening strips bleach the surface and can make teeth more sensitive over time.
- Nano-hydroxyapatite is the same mineral as your enamel. It settles into tiny cracks and strengthens the tooth, so teeth look brighter and feel less sensitive at the same time.
Japan has used it in toothpaste since the 1980s.
Can it really whiten teeth?
Teeth look yellow when enamel wears thin and the layer underneath shows through. Nano-hydroxyapatite helps strengthen the enamel, so teeth look brighter over time. There's no bleach, so the results don't wash away.
I have sensitive teeth. Will it help?
Sensitivity happens when worn enamel leaves tiny channels open to the nerve, so cold, hot or sweet things hit it directly. The mineral helps fill and seal those channels. Many people feel a difference within 2 to 3 weeks, and it keeps improving with daily use.
What about bleeding or sore gums?
The formula has no SLS, a foaming agent that can dry out and irritate gums. Pair it with the ultra-soft NanoBrush for the gentlest clean.
I have fillings, crowns or veneers. Is it safe?
Yes. It doesn't scrub or bleach anything, so it's safe with dental work.
Does it replace my regular toothpaste?
Yes. Use it morning and night in place of your usual toothpaste.
Is it safe to use every day?
Yes. It's the same mineral your teeth are made of, and daily use is how it works best.
When will I see whiter teeth?
Most people see a change in 4 to 8 weeks. Deeper stains can take longer. Smoother teeth and fresh breath start from the first brush.
Why your toothpaste isn't working
Most toothpaste is made to be cheap. It cleans, but it isn't built to protect your teeth.
Weak enamel is behind yellow teeth, sensitivity, cavities and bad breath.
That's why these problems keep coming back. A routine that only cleans the surface does nothing to repair it.
This is what your teeth are made of
Your enamel is about 96% mineral, and most of that mineral is hydroxyapatite.
Research shows that when you put this mineral back on your teeth, they take it up. It settles into the tiny cracks and makes your enamel stronger.
And when your enamel is strong, the problems ease on their own:
- Whiter teeth. From stronger enamel, with no bleach.
- Less sensitivity. The tiny channels to the nerve get sealed.
- Better cavity protection. Stronger enamel stands up to acid and bacteria.
- Stronger teeth. Every brush puts minerals back.
This is why we made Selene Nano Toothpaste
Hydroxyapatite costs more than fluoride. That's the main reason big brands leave it out.
We built our whole formula around it.
- Nano-hydroxyapatite as the main ingredient.
- Backed by research. The studies are linked on this page.
- Works every time you brush. Morning and night, every day.
- Nothing harsh. No fluoride, SLS or parabens.
Your teeth, week by week
Real change takes a little time. Here's what to expect:
-
Week 1-2
The first things you notice.
Your teeth feel smoother and your breath stays fresh for longer. Sensitivity can start to ease as the mineral fills the tiny exposed channels in your enamel.
86% of customers noticed less sensitivity in our survey.
-
Week 2-4
Surface stains start to lift.
Coffee, tea and wine stains begin to fade and your teeth look cleaner in daylight. Your gums feel calmer too, and cold drinks bother you less.
78% of customers reported calmer, less irritated gums.
-
Week 6-8
The brightness shows.
Stronger enamel hides more of the yellow layer underneath, so your teeth look brighter. This is when people around you start to notice.
91% of customers reported visibly whiter teeth.
-
Week 8-12
Stronger, healthier enamel.
After a few months of daily use your enamel is in better shape. Stronger enamel stands up better to acid and bacteria, which helps protect you from cavities.
It works by making your enamel stronger, so the results last.
