Klyyr vs David's Hydroxyapatite Toothpaste

Quick answer

Klyyr vs David's is a comparison of two fluoride-free, SLS-free nano-hydroxyapatite toothpastes in metal tubes. Davids Hydroxi™ publicly lists rod-shaped nano-hydroxyapatite and does not publish a percentage on the product pages reviewed for this guide.

Klyyr One+ discloses a combined 10% nano + micro blend and lists 16 ingredients. Davids sells multiple Hydroxi flavors and an EWG VERIFIED line. Formulas change. Read the current tube.

01
What both are
Fluoride-free, SLS-free hydroxyapatite toothpastes in metal tubes. Both use sodium cocoyl glutamate as the surfactant.
02
What David's emphasizes
Rod-shaped nano-hydroxyapatite, multiple flavors, and EWG VERIFIED Hydroxi SKUs. The public pages reviewed do not state a hydroxyapatite percentage.
03
What One+ emphasizes
A disclosed 10% nano + micro blend, a 16-ingredient list, and one peppermint + spearmint profile.

What the cited studies actually measured

There is no Klyyr-versus-Davids clinical trial on this page. Cited studies tested other hydroxyapatite formulas.

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.
Read the 18-month non-inferiority study
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.

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

One+ may fit if

You want the hydroxyapatite percentage printed, both nano and micro named, and a short ingredient list you can read in one pass.

David's may fit if

You want a specific Hydroxi flavor, an unflavored paste, or an EWG VERIFIED SKU. Those are legitimate reasons to choose Davids.

Packaging is not the whole decision

Both use metal tubes. Recycle where accepted locally. The formula still matters more than the tube story.

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.

01

Combined nano + micro hydroxyapatite, disclosed on the label. Ten percent is not a universal efficacy threshold.
02
16 listed ingredients
Water, Sorbitol, Glycerin, Potassium Sorbate, Hydroxyapatite (nano & micro), Xylitol, Sodium Cocoyl Glutamate, Cellulose Gum, Xanthan Gum, Zinc Citrate, Aloe Vera, Mentha Piperita (Peppermint) Oil, Mentha Viridis (Spearmint) Leaf Oil, Menthol, Sodium Benzoate, Stevia Rebaudiana Leaf/Stem Extract.
03
What is not in it
0 ppm fluoride. No SLS. No artificial dyes. Sodium cocoyl glutamate is the surfactant.
04
120 g aluminum tube
4.23 oz, approximately 90 brushings. Aluminum tube, HDPE cap. Recycle where accepted locally.

In short

Two metal tubes can still hide different amounts of the same mineral. Ask for the percentage.

01 Does David's disclose its hydroxyapatite percentage?

The public Hydroxi pages reviewed for this comparison list nano-hydroxyapatite and do not state a percentage. One+ discloses 10% nano + micro.

02 Are both SLS-free?

Yes, on the labels compared here. Both list sodium cocoyl glutamate.

03 Is One+ EWG VERIFIED?

No. Davids states EWG VERIFIED on Hydroxi pages. One+ publishes independent lot testing on the Labs page instead. Those are different programs.

04 Which is better for kids?

Neither page replaces a pediatric dentist. One+ is not a dedicated kids flavor. Use ADA amounts and spit. See hydroxyapatite toothpaste for kids.

05 Is Klyyr better than David's?

This page is a public-label comparison, not a Klyyr trophy. Exact-Net's 2026 ranking named Klyyr Best Overall and Davids Best Seller. Read the Best Overall recap. There is still no head-to-head clinical trial cited here.
