Product Details

7.5% rod-shaped nano-hydroxyapatite toothpaste — fluoride-free. Formulated to remineralize enamel, relieve sensitivity, and whiten by rebuilding the tooth surface rather than coating or bleaching it.

How do I use it?

Use exactly like your current toothpaste — brush twice daily for two minutes. No changes to your routine, no adjustment period. Most people notice teeth feeling smoother and less reactive to hot/cold within 1–2 weeks.

How does nano-hydroxyapatite protect against cavities and sensitivity?

Hydroxyapatite is the actual mineral your enamel is made of. When enamel wears down, it leaves microscopic gaps and exposed channels — that's what causes sensitivity, staining, and decay risk. This toothpaste supplies nano-sized particles that physically refill those gaps and plug the exposed channels, rather than just hardening or numbing the surface like fluoride or sensitivity toothpaste do.

Is nano-hydroxyapatite safe for daily use?

Yes. We use rod-shaped particles — the form studied and approved by the EU's SCCS for oral care, at 7.5% concentration (a number we disclose in full, unlike some competitors). If swallowed, hydroxyapatite dissolves rapidly in stomach acid with no established pathway into the bloodstream. It's gentle enough for daily use by the whole family

How is this different from fluoride toothpaste?

Fluoride hardens the outer layer of what's already there — it doesn't replace lost mineral. Hydroxyapatite is that mineral, delivered back to your teeth in a form small enough to physically rebuild the microscopic defects causing sensitivity and staining. Multiple clinical studies show it performs on par with 500ppm fluoride toothpaste for remineralization — without the fluoride.

Is this backed by research?

Nano-hydroxyapatite's dental use began with NASA research in the 1970s and has been used in Japan and across Europe since 1980. It's supported by clinical studies published in journals including the Journal of Dentistry and Dental Research Journal, showing comparable or better outcomes than fluoride for remineralization and sensitivity relief.

"I switched after my dentist mentioned hydroxyapatite as an alternative to fluoride , I wasn't expecting much, honestly. I'd been dealing with sharp pain every time I drank anything cold for almost a year, to the point where I'd stopped ordering ice water without thinking about it. About two weeks in, I noticed I could actually drink my coffee without wincing. It's been two months now and the sensitivity is basically gone. My husband's started using my tube instead of his."

ONE MINERAL. YOUR TEETH'S OWN REPAIR MATERIAL.

Nano-Hydroxyapatite

Hydroxyapatite is the calcium-phosphate mineral that makes up 95–97% of your tooth enamel — it's not an additive, it's what teeth are literally built from. "Nano" means it's engineered into particles small enough to physically get inside the microscopic cracks and pores on your tooth surface, instead of just sitting on top of it.

How It Works:
  1. 1. Reaches into microscopic cracks and gaps in your enamel — particles are small enough to physically lodge into the same defects causing sensitivity and staining.
  2. 2. Acts as a calcium-phosphate reservoir, supplying the exact minerals your enamel needs to rebuild itself.
  3. 3. Plugs the exposed channels in your dentin that transmit hot, cold, and sweet sensations straight to the nerve — the direct mechanism behind sensitivity relief.
  4. 4. Bonds to form a new, denser surface layer — smoother, more light-reflective, and more resistant to new staining.
  5. 5. Dissolves harmlessly if swallowed, with no established pathway into the bloodstream — unlike fluoride.

Wish I found this sooner

I'd basically stopped ordering ice water without thinking about it. Tried Sensodyne for almost a month with barely any change. Switched to this and by week two I could actually drink coffee again without wincing.

Not a miracle but close

I'm skeptical of anything that claims to fix sensitive teeth. This didn't make it disappear overnight, but the sharp zing from cold drinks has genuinely faded, and my teeth feel smoother when I run my tongue over them.

Better than prescription drugs

I mentioned I was using this at my last cleaning half-expecting to get talked out of it. She said the hydroxyapatite research is solid and to keep going. That was enough to make me a repeat customer.

Finally sleeping through the night

Whitening strips always left my gums wrecked and my teeth aching for days after. This is the first thing that's made my teeth look noticeably brighter without a single twinge of sensitivity.

"I'd stopped ordering ice water without even realizing I was doing it. Tried Sensodyne for almost two months with barely any change, my dentist said it takes time to 'build up' but mine never did. Three weeks into this and I drank an iced coffee without thinking twice. My Wife asked why I stopped wincing before I even mentioned I'd switched."

"I used charcoal toothpaste for almost a year because I thought I was doing the responsible thing. My teeth got more sensitive and honestly looked duller, not whiter. Two months on this and they're smoother and visibly brighter, my hygienist actually asked what changed at my last cleaning."

WHAT TO EXPECT: YOUR ENAMEL REBUILD TIMELINE

FIRST USE

Rebuilding Starts on Contact

  • Nano-hydroxyapatite particles begin binding to your enamel and filling microscopic gaps from the very first brush
  • Teeth feel noticeably smoother, less rough — not gritty like some remineralizing pastes
  • No sting, no adjustment period, no "getting used to it"
  • Works with your existing routine — nothing to change

WEEK 1–2

Sensitivity Starts Easing

  • Exposed dentin channels begin closing as particles fill in
  • Cold drinks, ice cream, and hot coffee start feeling less sharp
  • Teeth feel smoother and less reactive day to day
  • Surface starts resisting new stains as it becomes denser

MONTH 1+

The New Normal: You Stop Thinking About It

  • Ordering ice water without a second thought
  • No more brown/yellow trade-off from sensitivity toothpaste workarounds
  • Visibly smoother, brighter enamel as light reflects more evenly off the rebuilt surface
  • Ongoing protection against future demineralization — not just symptom relief

Most oral care treats damage after it's already visible or felt. What makes nano-hydroxyapatite compelling is that it works at the actual site of the loss — the enamel crystal structure itself — where the mineral was stripped away in the first place. Hydroxyapatite has a 40+ year track record in Japan and across Europe for exactly this reason, since Japan's first hydroxyapatite toothpaste launched in 1980. We've always known hydroxyapatite is the mineral your enamel is made of. The innovation here is engineering it into a particle small enough to actually get inside the microscopic gaps causing sensitivity, staining, and decay — and rebuild them.

FREQUENTLY ASKED QUESTIONS

When is the best time to use it?

Morning and night, like your regular toothpaste — no special timing required. Consistency matters more than timing, since remineralization builds with regular use.

How quickly does it start working?


Mineral binding starts from your very first brush. Most people notice teeth feeling smoother within the first week, with sensitivity easing over the next 1–2 weeks of consistent use.

Can I use this alongside my regular mouthwash or whitening routine?


Yes. It works well alongside most oral care products. If you use a fluoride mouthwash, note that combining fluoride and hydroxyapatite hasn't been shown to add extra benefit — most people using this toothpaste switch to a fluoride-free rinse to stay consistent with a fully fluoride-free routine.

Who shouldn't use this product?

If you have active, severe dental disease (deep decay, significant enamel erosion) your dentist may recommend supervised fluoride treatment alongside or instead of this — hydroxyapatite is well-suited for prevention and mild-to-moderate remineralization, but severe existing damage should be assessed by a dentist first. Otherwise, it's suitable for daily use by nearly everyone.

Can my kids use it?

Yes — this is actually one of the biggest reasons families choose to switch. Because it's fluoride-free, there's no fluorosis or swallowing risk to manage, which means no more rice-grain-amount anxiety at brushing time. It's gentle enough for the whole household to share one tube, from toddlers to adults. [Consult your pediatric dentist for children under 2.]

Can my kids use it?

Our povidone-iodine nasal spray is formulated for ages 12 and above. For younger children or children with any medical problems, we recommend consulting your paediatrician. Many of our customers are parents who use the spray themselves to avoid catching the bugs their children bring home from school and daycare.

Is the tube travel-friendly?

Yes, TSA carry-on compliant, no special storage or refrigeration needed.
