The Science of Nano-Hydroxyapatite (nHAp)
Tooth enamel is the hardest substance in the human body, but once it erodes, your body cannot naturally regrow it — until now. Discover why leading dental scientists consider Nano-Hydroxyapatite the greatest breakthrough in oral care in 60 years.
Microscopic Repair in Action
Holydeer's 7.5% nHAp particles (20nm scale) flow into exposed dentin tubules, bonding directly with natural apatite crystals to seal nerve channels and halt sensitivity at the root.
What Is Hydroxyapatite?
Hydroxyapatite, Ca₁₀(PO₄)₆(OH)₂, is a naturally occurring mineral form of calcium apatite. It constitutes approximately:
- 97% of human tooth enamel
- 70% of tooth dentin
- 65% of bone mass
In 1970, NASA originally researched synthetic hydroxyapatite for astronauts who lost bone and tooth density in zero-gravity. Modern biomedical laboratories refined this mineral into “nano” scale particles capable of penetrating the microscopic pores of teeth.
Why the “Nano” Size Matters
Regular calcium or macro-hydroxyapatite is too large to enter tooth enamel defects. At 20 to 50 nanometers, Holydeer's Nano-Hydroxyapatite is small enough to:
Nano-Hydroxyapatite vs Traditional Fluoride
Decades of research in Japan, Germany, and the United States have validated nHAp as equal to or superior to fluoride.
Nano-Hydroxyapatite (Holydeer)
Biocompatible- Identical to tooth structure: Actually rebuilds genuine enamel rather than creating a foreign surface coating.
- 100% Non-toxic: Safe if swallowed. Zero risk of dental fluorosis or gastrointestinal toxicity.
- Direct tubule occlusion: Plugs exposed dentin channels to eliminate nerve sensitivity permanently.
- Natural whitening effect: Smoother enamel diffuses light, creating a bright porcelain appearance without bleaching chemicals.
Traditional Sodium Fluoride
Chemical Agent- •Thin surface layer: Creates fluorapatite on the outer surface only; does not restore natural lost enamel depth.
- •Toxicity warning: Must carry a poison warning label required by health agencies. Unsafe for young children who swallow.
- •Temporary nerve numbing: Sensitive toothpastes rely on potassium nitrate to numb nerves rather than physically healing the breach.
- •Fluorosis risk: Overexposure can cause permanent cosmetic white spots and pitting on developing teeth.
The Holydeer Formulation Standard
Every tube of Holydeer is produced under strict ISO-22716 & GMP laboratory quality guidelines.
