Klyyr vs. Mouthology.

Quick answer

Klyyr vs Mouthology is one of the cleanest concentration comparisons: both brands publish 10% hydroxyapatite. Mouthology describes 10% rod-shaped nano-HAp. Klyyr describes a combined 10% nano + micro blend.

Both compared pastes are fluoride-free, SLS-free, and xylitol-containing. The decision is not whether one prints a number; both do. It is whether you prefer Mouthology's nano-only, rod-shape story or Klyyr's mixed-particle approach, plus differences in flavor, formula details, and tube size.

Same 10% headline, different particle mix

  • 01

    Both clear the disclosure test

    Mouthology and Klyyr each publish 10%. No third-party percentage guesses are needed.

  • 02

    Particle strategy is the real split

    Mouthology describes rod-shaped nano-HAp. One+ combines nano and micro HAp.

  • 03

    Do not transfer kids claims

    Mouthology sells a separate kids formula. One+ is one mint paste and instructs users to spit.

Which one fits your routine?

Mouthology may fit if

You specifically want a disclosed 10% nano-only formula and prefer its flavor, subscription, or family product range.

One+ may fit if

You want nano and micro HAp together at 10%, a 120 g aluminum tube, and a single peppermint + spearmint formula.

Ten percent is not the verdict

Both publish the same headline concentration. There is no head-to-head clinical trial cited here.

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

In short

When both brands disclose 10%, the honest comparison moves to particle mix and the rest of the formula.

01 Do Klyyr and Mouthology both contain 10% hydroxyapatite?

Yes. Mouthology describes 10% nano-HAp. One+ describes a combined 10% nano + micro blend.

02 Is nano + micro better than nano only?

No head-to-head trial on these products is cited here. They are different particle strategies, not a proven ranking.

03 Are both fluoride-free and SLS-free?

Yes for the adult pastes compared.

04 Can children use either toothpaste?

Mouthology sells separate kids products. One+ is not a dedicated kids paste and instructs users to spit. Ask a child's dentist before changing a fluoride routine.

05 Which brand is more transparent?

Both publish the 10% HAp concentration and full ingredient information for the products reviewed. The remaining transparency difference is particle description and product-level detail.
