How a Biomimetic Mineral is Reinventing Oral Care

Renamel® works by using nano-hydroxyapatite, the exact same mineral that makes up your natural tooth enamel. Instead of just cleaning or masking problems, it rebuilds your teeth from the outside in. Discover the science behind this revolutionary approach.

The Problem with Current Options

For decades, oral care has presented a compromise:

  • Different approaches: Fluoride toothpastes are widely used for caries prevention. Some consumers prefer fluoride‑free options for personal reasons.
  • Sensitivity care: Some sensitivity products act by desensitising the nerve; others, like nano‑hydroxyapatite formulas, help occlude exposed dentinal tubules to reduce sensitivity with continued use.

Today, biomimetic options allow fluoride‑free routines while maintaining a focus on daily care.

The Nano-Hydroxyapatite Solution

Nano-hydroxyapatite (n-HAp) offers a smarter, biomimetic solution. "Biomimetic" means it mimics nature. Since n-HAp is the very mineral that comprises 97% of your tooth enamel, your body recognizes it and uses it to:

  • Help remineralise enamel: Nano‑particles deposit on enamel, helping to fill microscopic defects and support remineralisation.
  • Reduce sensitivity with continued use: By occluding dentinal tubules, n-HAp helps reduce triggers like cold or touch over time.19

With regular brushing, this cosmetic mechanism supports stronger‑feeling teeth and comfort.

The Science Made Simple

Here's what happens when you brush with Renamel®:

  • Deposition: Billions of nano‑hydroxyapatite particles are deposited onto the tooth surface.
  • Integration: These particles bind to enamel, helping to fill microscopic fissures and areas of demineralisation.
  • Restoration: Smoother, mineral‑rich surfaces improve appearance and comfort.
  • Daily freshness: Xylitol is a non‑fermentable polyol used in oral‑care; studies report reductions in plaque quantity and mutans streptococci with regular use.1016
Why It's Perfect for Families

Nano‑hydroxyapatite is a biomimetic mineral found in enamel and has been widely studied for use in cosmetic oral‑care.

  • Fluoride‑free option: For those seeking fluoride‑free daily care.
  • For all ages: Suitable for family use. Children should brush under supervision and use a pea‑sized amount.
  • Balanced approach: Combine with regular brushing and professional dental care.
