"This Is The Future Of Toothpaste"
nHAP fills microscopic lesions in enamel using the same mineral your teeth are already made from, rebuilding structure rather than just coating the surface.
By filling surface roughness with white mineral particles, nHAP creates a naturally smoother, brighter enamel surface. Research supports up to one shade whiter with consistent daily use.
nHAP particles occlude the tiny exposed dentine channels that trigger sensitivity to temperature and pressure, with clinical research reporting measurable relief from two weeks of regular use.
Zinc citrate and organic mint address the bacteria behind bad breath without wiping out your oral microbiome. No SLS, no harsh foaming agents, just clean results.
Cleaner ingredients. Cleaner teeth. When you know exactly what you're putting in your mouth and why, it shows.
For years, the word "nano" has been used to scare people away from nano-hydroxyapatite, often by brands that simply do not use it. The EU's own safety regulator disagrees, and the gap just got bigger.
In March 2023, the Scientific Committee on Consumer Safety (SCCS) set the safe limit for nHAP in toothpaste at 10%. In June 2025, after reviewing further safety data, they raised that limit to 29.5%, nearly three times higher.
Three benefits the research consistently points to, and how the mineral gets there.
Hydroxyapatite makes up roughly 97% of tooth enamel by weight. Because nHAP particles are the same mineral, the tooth surface integrates them directly rather than coating over the area.
At nano scale, particles are small enough to sit inside early demineralised areas and exposed dentine channels, the structures linked to sensitivity, rather than only sitting on top of the surface.
Consistent twice daily use builds a smoother, more mineral dense surface over time, which is more resistant to the acid attacks that lead to future sensitivity and cavities.
Not all nano hydroxyapatite is equal. The prevailing assumption is that 10% is the minimum effective concentration, but research increasingly points to particle quality as the bigger variable.
Our nHAP is rod shaped, with a median length of 27.6 nanometres and width of 15.4 nanometres, well below the 1.3 micrometre adhesion threshold identified in the research literature [Study 10]. The particles are uncoated, not surface modified, and contain no needle shaped structures.
This matters because particles above that threshold simply cannot bind to the enamel surface as effectively, regardless of how high the headline concentration number is.
Engineered to a recognised safety standard, particle size, shape, aspect ratio and composition designed to meet the EU safety committee's specification for nano-materials in oral care.
Synthesised, not milled, produced in aqueous solution for precise, consistent sub-50 nanometre particles, rather than ground from bone, eggshell, or salt-phosphate reactions.
Well below the adhesion threshold, research shows HAP particles above 1.3 micrometres have limited enamel adhesion. Ours measure a median 27.6 nanometres in length.
We are not here to tell you fluoride does not work. We are here to show you why we chose a different mineral, so you can make your own call.
RDA (Relative Dentin Abrasivity) measures how much a toothpaste wears down enamel with daily brushing. The lower the number, the gentler the formula.
Most everyday toothpastes sit between 30 and 160 RDA. Regulatory guidance treats anything under 250 RDA as safe. MGR Toothpaste Tablets measure 21.38, gentle enough for sensitive teeth, daily use, and long term enamel health.
