Five Revolutionary Benefits in Every Tube

Hardness recovery in laboratory testing

Imagine if you could give your teeth the exact same mineral they're naturally made of. That's what Renamel® does with 10% nano‑hydroxyapatite—the precise building block of healthy enamel.

Your Teeth's Natural Blueprint

Nano‑hydroxyapatite has the exact same crystal structure as your natural tooth enamel. When you brush, these tiny particles seek out microscopic damage—chips, scratches, and weak spots you can't even see—and fill them in perfectly.

The Perfect Match

• Biomimetic Integration: Since it's made of the exact same mineral as your teeth (97% of enamel is hydroxyapatite), it doesn't just sit on the surface—it actually integrates and becomes part of your tooth structure
• Calcium Phosphate Reservoir: Acts as a mineral reservoir, keeping your enamel in a state of super‑saturation that enhances remineralisation
• Progressive Strengthening: With every brush, you're not just cleaning—you're rebuilding, making teeth stronger and more resilient over time

In rigorous laboratory tests, teeth treated with nano‑hydroxyapatite showed hardness recovery vs. baseline after demineralisation, with higher recovery than fluoride under test conditions.³

Reported relief in 2–4 weeks (with continued use)

That sudden, sharp pain when you sip something cold or bite into something sweet? Unlike treatments that just numb the pain, Renamel® tackles the problem at its source by physically sealing the tiny channels that allow pain signals to reach your nerves.

Real Relief, Real Fast

• Week 1-2: Initial sealing begins—you might start noticing small improvements
• Week 2-4: Significant relief as clinical studies show measurable pain reduction
• Ongoing: Continued improvement as more tubules are sealed with daily use

A Completely Different Approach

Most sensitivity treatments work by numbing your teeth or temporarily blocking pain signals. Nano‑hydroxyapatite is revolutionary because it actually fixes the underlying problem—those tiny channels (called dentinal tubules) that expose your tooth's nerve become physically sealed with the same mineral your teeth are made of.

Think of it like filling in cracks in a wall instead of just painting over them. The result? Ongoing relief that improves with continued use, without harsh bleaching actives.

In controlled clinical studies, participants reported improvements after 2–4 weeks of use on standardised sensitivity scales.¹⁹

Supports a balanced oral environment

Your mouth is home to hundreds of different bacteria—some helpful, others harmful. Renamel® supports daily oral hygiene to help reduce plaque and maintain a balanced environment.

Triple-Action Bacterial Defense

• Nano‑hydroxyapatite: Helps smooth and remineralise enamel surfaces, making them less hospitable to plaque adhesion
• Xylitol: Non‑fermentable polyol used in oral‑care; clinical and in vitro studies report reductions in plaque quantity and mutans streptococci with regular use.¹⁰¹⁶

Everyday friendly

Formulated without peroxide or SLS, and with non‑fermentable xylitol, as part of a gentle daily routine.

Use consistently

Some studies observed sustained microbial effects after regular xylitol use; findings vary by population and protocol.¹¹⁰

Helps whiten through restoration (not bleaching)

Forget harsh bleaching chemicals that can damage your teeth and cause sensitivity. Renamel® creates a naturally brighter smile through an elegant process: nano‑hydroxyapatite builds up a white, opaque layer that blocks yellowing from deeper layers while creating smoother surfaces for better light reflection.

The Science of Natural Brightness

A systematic review of clinical studies describes dual mechanisms behind nano‑hydroxyapatite appearance benefits.⁸

Two Ways to Brighter Teeth

• Immediate Effect: Fills tiny surface imperfections, creating smoother surfaces that reflect light more evenly for an instant brightening effect
• Long-term Whitening: Builds up a white, opaque protective layer that prevents the natural yellow color of dentin from showing through your enamel
• Stain Prevention: The smoother, more mineralized surface makes it harder for new stains to stick and easier to remove them during brushing

Gentle on Sensitive Teeth

Unlike peroxide bleaching, nano‑hydroxyapatite is non‑bleaching and compatible with sensitive teeth.

Studies report that hydroxyapatite can make teeth appear whiter and improve light reflection from enamel.⁸

Fluoride‑free and suitable for family use

Renamel® is a fluoride‑free daily toothpaste formulated with nano‑hydroxyapatite and xylitol for effective everyday oral care. As with any toothpaste, spit out after brushing.

About clinical research

Head‑to‑head trials have reported similar caries outcomes for hydroxyapatite vs. fluoride toothpastes in certain populations and settings.¹² This information is provided for education only. Renamel® is a cosmetic product.

For the whole family

Hydroxyapatite has been studied as a fluoride‑free option across age groups. Always supervise children while brushing and use a pea‑sized amount.

Why This Changes Everything

• Fluoride‑free alternative: For consumers seeking fluoride‑free daily oral care
• Gentle: Non‑bleaching appearance benefits and sensitivity‑friendly formulation
• Daily use: Brush twice daily and spit out excess paste

This represents the future of oral care: smart, effective, and completely natural. Effective enamel rebuilding using the same mineral your teeth are naturally made of, combined with precision bacterial targeting from nature's own cavity‑fighter, all with complete safety for every member of your family.
