🔧 What Is Nano-Hydroxyapatite?
Nano-hydroxyapatite (nHAp) is a biomimetic mineral mirroring the natural structure of tooth enamel—comprising around 97% of its composition. (link) In toothpaste form, such as hydroxyapatite toothpaste, these nano-sized particles penetrate enamel pores, repairing micro-cracks and rebuilding its mineral structure. This neen remineralizing toothpaste serves as a fluoride alternative. GQ.
🧪 How It Works
- Fills Micro-Pores
nHAp particles act as a crystal nucleus, drawing calcium and phosphate to seal demineralized enamel. (read here) - Rebuilds and Strengthens
Studies show that 10–15% hydroxyapatite toothpastes offer comparable enamel remineralization to fluoride-based ones (500–1,450 ppm). (read here) - Reduces Sensitivity
nHAp seals exposed dentin tubules, lowering sensitivity—even after whitening. (read here) - Safe & Biocompatible
Unlike fluoride, nHAp is non-toxic if swallowed, ideal for children and sensitive users. (read here)
🔄 NHA vs. Fluoride: What Do the Studies Say
- A 2019 clinical trial found no statistical difference in preventing caries between nHAp and fluoride toothpastes in adults over a year (Wikipedia)
- A pH cycling study confirmed that 10% nHAp achieved similar, and sometimes superior, remineralization compared to 500 ppm fluoride (read here)
- An in situ orthodontic trial showed 10% micro-HAp was non-inferior to 1,400 ppm fluoride among high-risk patients (read here)
🎯 Why Choose Neen EnamelProTect+?
- Contains 10–15% nano-hydroxyapatite and potassium citrate—targeting enamel and sensitivity.
- Fluoride-free, non-abrasive, and safe even if swallowed.
- Clinically supported, matches fluoride’s effects, and preserves enamel without side effects.
- Supports enamel repair, protects against demineralization, and feels gentle.
✅ Final Thought
neen’s enamel-strengthening toothpaste offers a science-backed, fluoride-free alternative to conventional dental care. It rebuilds enamel, reduces sensitivity, and protects oral health—naturally and safely, every day.
