Our key ingredient

Nano-hydroxyapatite, explained.

Hydroxyapatite is the main mineral in your enamel. In a toothpaste, what decides whether it works is the particle size, the shape and how much of it is in the tube.

Nano-hydroxyapatite, explained.
  1. 1

    It's what your enamel is made of

    Hydroxyapatite is the main mineral in tooth enamel. Nano-sized particles are small enough to reach the enamel surface where it counts.

  2. 2

    How it helps remineralize*

    Every time you brush, nHA particles land on your enamel, settle into microscopic gaps and support your teeth's natural remineralization.

  3. 3

    10% is the level the research uses

    We use the concentration from the published studies that tested nHA head-to-head against fluoride.

10%

Why exactly 10%

It's the amount used in the clinical research. A bigger number on the box doesn't come with better evidence.

nm

Nano-sized particles

Size and shape decide whether nHA reaches the enamel surface, so the percentage on our label actually means something.

✓

Safe if swallowed

No fluoride, so it's a toothpaste the whole family can use without worrying.

*Based on published clinical research on nano-hydroxyapatite.

Finally switched off fluoride

I'd been wanting a fluoride-free option for ages but most of them felt like brushing with chalk. This one actually foams a little and leaves my teeth feeling super smooth, like right after a cleaning.

Smooth teeth feeling is real

Been using it about 3 weeks. My teeth feel glassy smooth every morning. The mint is mild, not that burning kind. Already ordered the 5 pack.

Whole family uses it now

Bought it for me, now my husband and both kids use it. Love that I don't have to stress if my 5 year old swallows a bit.

Great, just wish it was minty-er

Love how my mouth feels after brushing. Taste is pretty subtle so if you like a strong mint it might not be for you. Still buying again.

Teeth look brighter

Not a whitening strip level change obviously but my teeth honestly look brighter and less dull after a few weeks. No sensitivity at all which is what I get with peroxide stuff.

I was skeptical about the hype around hydroxyapatite but I'm a convert. Brush, spit, don't rinse. My mouth feels cleaner for longer.
