Concentration

Label fact · Not a universal efficacy threshold

10% hydroxyapatite toothpaste.

Quick answer

10% hydroxyapatite toothpaste means the paste lists hydroxyapatite at a 10% concentration. Klyyr One+ is a 10% hydroxyapatite toothpaste: a combined nano + micro blend, clearly disclosed.

Ten percent is not a magic number for every mouth. It is the concentration used in one 18-month adult study of a different 10% HAp formula that was non-inferior to 1450 ppm fluoride on that study's primary caries endpoint. That result is ingredient-level evidence, not a Klyyr clinical trial.

  • 01

    What 10% refers to

    On One+, 10% is the combined concentration of nano and micro hydroxyapatite. It is not 10% nano plus another 10% micro.

  • 02

    Why shoppers search it

    Published research on other hydroxyapatite toothpastes often uses around 10%. Searchers want a paste that names the percentage instead of hiding it.

  • 03

    What it does not prove

    A disclosed 10% does not make One+ clinically proven, and it does not make a higher or lower percentage automatically better.

Topic Category pattern Typical HAp paste Klyyr One+ 10% disclosed
HAp concentration Often undisclosed, or named only as nano-HAp 10% nano + micro, disclosed
Particle sizes Often nano only, or unnamed Nano and micro, both listed
Fluoride Usually 0 ppm in this category 0 ppm
Ingredient count Often 20+ with botanicals or abrasives 16 fully listed ingredients
SLS Varies None
Why 10% is cited Matches a common study concentration Same category concentration; different formula from the study

Category patterns describe common hydroxyapatite toothpastes. Individual labels vary. One+ facts are from the product label.

What the cited studies actually measured

The 18-month study is why many people search for 10% hydroxyapatite toothpaste. It tested a different formula. Use it to understand the ingredient category, not as a Klyyr result.

  1. 18-month adult clinical trial · different formula

    Caries endpoint

    In one 18-month adult study, a 10% HAp toothpaste was non-inferior to 1450 ppm fluoride for the primary caries endpoint. The study tested a different formula.

  2. Sensitivity study · small HAp arm · different formula

    Dentin sensitivity

    Hydroxyapatite toothpastes have been studied for dentin sensitivity and interaction with exposed tubules. One cited HAp arm included only ten participants and used a different formula.

  3. In-vitro experiment · different commercial paste

    Surface stains

    An in-vitro experiment measured stain removal after 180 seconds for another commercial HAp toothpaste. That is laboratory data, not a Klyyr whitening result.

How to choose

10% may be what you want if

You are comparing hydroxyapatite toothpastes and want the concentration on the label, not an implied amount. One+ discloses a combined 10% nano + micro blend.

Ask a dentist first if

You are leaving a prescribed fluoride toothpaste, shopping for a child, or managing high cavity risk. Concentration is only one part of a routine.

Skip the leap

Do not treat another 10% paste's clinical trial as a Klyyr result. Formula, particle mix, and study design all change what a percentage can mean.

The Klyyr One+ formula

One+ is fluoride-free toothpaste with a clearly disclosed 10% nano + micro hydroxyapatite blend, 16 listed ingredients, peppermint + spearmint, no SLS, and no artificial dyes.

In short

Look for the percentage on the label. Then read what that percentage actually includes.

01 What does 10% hydroxyapatite toothpaste mean?

It means hydroxyapatite is present at a 10% concentration. On One+, that 10% is a combined nano + micro blend listed on the label.

02 Is 10% hydroxyapatite enough?

There is no universal enough. Ten percent appears in published research on other formulas, including an 18-month adult non-inferiority study. That study did not test Klyyr.

03 Is a higher hydroxyapatite percentage better?

Not automatically. A higher number on a different paste is a different formula. Compare the full label, particle sizes, and whether any study tested that exact paste.

04 Is One+ 10% nano-hydroxyapatite?

One+ is 10% nano + micro hydroxyapatite, combined. See nano vs micro hydroxyapatite toothpaste.

05 Did the 18-month study use 10%?

Yes. It used a 10% hydroxyapatite toothpaste of a different formula, compared with 1450 ppm fluoride, in adults, for one primary caries endpoint.
