PAP + Hydroxyapatite Formula
Hydroxyapatite rebuilds enamel from within — it's the same mineral your teeth are made of. PAP lifts stains safely without peroxide or sensitivity. Together, they repair, strengthen, and whiten simultaneously.
Real repair + fast whitening — not just a single ingredient.

Additional Benefits
Hydroxyapatite is the same mineral your teeth are made of. Instead of coating your enamel like fluoride or scrubbing it like charcoal, GetSmiley uses clinical-strength hydroxyapatite to rebuild and strengthen teeth from within — while our PAP stain-lifting system whitens fast without peroxide or sensitivity. This isn't a cosmetic toothpaste. It's a repair + whitening system for daily use.

Dental panel reviewFrom NASA's Space Program to Your Smile
This isn't just another toothpaste ingredient. Nano-hydroxyapatite was developed by NASA scientists to solve one of space travel's biggest challenges.
The Discovery
NASA researchers observed astronauts losing bone and tooth minerals in microgravity. NASA scientist Bernard Rubin discovered that growing hydroxyapatite crystals in a gel—similar to how they form in bones and teeth—could repair tooth surfaces.
This research led to a patented method for creating nano-hydroxyapatite (nHA) toothpaste that mimics the natural mineral.
Japan's Dental Breakthrough
Japanese researchers adapted NASA's breakthrough for oral care. Since enamel is naturally 97% hydroxyapatite, nano-hydroxyapatite could repair weakened enamel, fill microscopic cracks, and reduce sensitivity.
It works by depositing minerals back onto the tooth surface, strengthening enamel and preventing early decay.
Goes Mainstream
Hydroxyapatite became the #1 toothpaste ingredient in Japan, outselling fluoride 3:1. Europe followed. Now it's finally breaking through in the US.
Dentists now call it "the gold standard" for enamel repair

Frequently Asked Questions
Hydroxyapatite is the main mineral that makes up your tooth enamel (97% of it!). Unlike fluoride which coats teeth, hydroxyapatite actually integrates into your enamel to rebuild and strengthen it from within. Clinical studies show it's just as effective as fluoride for preventing cavities, but with the added benefits of whitening and zero sensitivity.
No! 98% of our users report zero sensitivity. In fact, many people with existing sensitivity find relief when they switch to hydroxyapatite because it strengthens enamel rather than stripping it. If you've experienced sensitivity with whitening products before, you'll love GetSmiley.
