89%

of adults using a 10% hydroxyapatite toothpaste had no increase in the study’s decay index over 18 months. The formula was non-inferior to 1450 ppm fluoride for that endpoint. The study tested a different formula, not Klyyr One+.

Particle science

Two mineral sizes. Two interaction scales.

Klyyr hydroxyapatite toothpaste — Extreme close-up of a bright, healthy smile with glossy lips

Nano and micro hydroxyapatite are the same enamel-like mineral at two particle-size ranges. Published ingredient research examines how smaller particles interact with microscopic defects and dentinal tubules while larger particles remain closer to the tooth surface. One+ includes both at a combined 10% concentration.

Ultra-fine crystals are studied for their interaction with microscopic surface defects and exposed dentinal tubules.

Scale

Micro-hydroxyapatite

The surface-scale cluster.

Larger mineral clusters remain closer to the tooth surface, where ingredient studies examine their contribution to a mineral layer.

Scale
Typically 5–10 microns — fifty to five hundred times larger than an individual nano crystal.
Shape
Not one giant rod, but hundreds of tiny crystallites fused into a porous, mostly spherical cluster.

Larger particles remain closer to the tooth surface in published ingredient research.

What to expect

A ritual worth repeating .

Mint-forward flavor, light foam, two minutes morning and night—the sensory side of showing up twice a day.

  1. FIRST BRUSH
    Mint-forward, with light foam.
    Expect a smooth paste, a peppermint-and-spearmint profile, and less foam than an SLS toothpaste.

  2. TWICE DAILY
    Consistency creates contact time.
    Brush gently for two minutes, morning and night. Spit after brushing rather than intentionally swallowing.

How it works

How to use

Two minutes. Twice a day.

No new ritual. Just a better version of the one you already have.

View steps
  1. Use a pea-sized amount

    Apply ONE+ to a soft-bristle toothbrush. A little goes a long way.

  2. Brush for two minutes

    Brush gently, morning and night, reaching every surface of every tooth.

  3. Spit. Don't rinse.

    Spit after brushing. Follow the product directions and any advice from your dentist.

For children under 3, use a rice-grain amount; for ages 3–6, use a pea-sized amount. Supervise brushing and encourage children to spit rather than intentionally swallow.

01 How do I use ONE+?

Brush twice daily with a pea-sized amount for two minutes. Spit without rinsing so a light film remains on the teeth. Use a soft-bristle brush and brush gently; consistency matters more than pressure.

02 How does hydroxyapatite compare with fluoride?

Hydroxyapatite is a fluoride-free alternative with growing clinical evidence. In one 18-month adult study, a 10% HAp toothpaste was non-inferior to 1450 ppm fluoride for the study's primary caries endpoint. That study tested a different formula, so it is ingredient-level evidence—not a Klyyr clinical result. Read the hydroxyapatite vs fluoride comparison.

03 Why use both nano- and micro-hydroxyapatite?

Nano and micro refer to particle-size ranges. Published ingredient research examines how smaller particles interact with microscopic surface defects and dentinal tubules, while larger particles remain closer to the tooth surface. One+ includes both at a combined 10% concentration. Read nano vs micro hydroxyapatite toothpaste.

04 Was Klyyr named best overall 10% nano-hydroxyapatite toothpaste?

Yes. In Exact-Net's 2026 ranking, Dr. Rossouw named Klyyr Best Overall, ahead of Genvyne, Davids, and Mouthology. That is his editorial pick, not a clinical contest. Read the Best Overall recap.

05 Can children use it?

For children under 3, use a rice-grain amount; for ages 3–6, use a pea-sized amount. A caregiver should supervise brushing and encourage children to spit rather than intentionally swallow. Ask your child's dentist about individual needs, especially when switching from a fluoride toothpaste. See hydroxyapatite toothpaste for kids.

06 Does it help with sensitive teeth?

Hydroxyapatite toothpastes have been studied for dentin sensitivity, including their interaction with exposed tubules. Those studies evaluated other formulas, so they do not guarantee a result from One+. Talk with your dentist if sensitivity is severe, new, or persistent. Read hydroxyapatite toothpaste for sensitive teeth.

07 Is ONE+ fluoride-free and SLS-free?

Yes. One+ contains 0 ppm fluoride and uses sodium cocoyl glutamate instead of sodium lauryl sulfate (SLS) for a lower-foam brush. All 16 ingredients are listed above. Read SLS-free hydroxyapatite toothpaste.

08 How long does one tube last?

Each 120 g tube provides approximately 90 brushings. Actual use varies by person and amount used.

09 How does the subscription work?
