By Alexander Angeloff, founder of TranscenDental. We make a hydroxyapatite toothpaste, so we're not neutral, but every brand fact below comes from that brand's own website, checked in October 2026.
Hydroxyapatite toothpaste has gone from a niche Japanese product to one of the fastest-growing categories in oral care. That also means a lot of marketing. Some brands use a meaningful amount of hydroxyapatite; others put a trace on the label and the word "hydroxyapatite" on the front.
This guide explains how to choose the best hydroxyapatite toothpaste for you: what concentration to look for, nano vs. micro particles, the ingredients around it, and how popular brands compare.
What I brush with every day
What hydroxyapatite toothpaste does
Hydroxyapatite (sometimes called calcium hydroxyapatite) is the calcium phosphate mineral that makes up most of your tooth enamel and much of your dentin, which is why it matters so much for enamel health. In toothpaste, especially in nano-sized particles, it:
- Remineralizes enamel and supports overall oral health by depositing mineral on the surface and into early areas of mineral loss
- Reduces sensitivity by sealing the tiny tubules in exposed dentin
- Smooths the surface, so teeth look glossier and pick up fewer stains
- Helps prevent tooth decay as a fluoride-free alternative in your oral care routine
The research is solid and growing. In an 18-month randomized trial in adults, hydroxyapatite toothpaste was not inferior to fluoride toothpaste for preventing cavities. For the full science, read nano-hydroxyapatite toothpaste: benefits and safety.
How to choose a hydroxyapatite toothpaste: 6 things to check
1. A stated concentration
Concentration is the most important number, and the easiest to hide. Many clinical studies of nano-hydroxyapatite use around 10%, which is why 10% has become the benchmark. If a brand won't say how much it uses, you can't compare it. Some list a percentage of a hydroxyapatite raw material rather than the amount in the finished toothpaste, so read the fine print.
2. Nano vs. micro hydroxyapatite
- Nano-hydroxyapatite (n-HA, nHAp) has particles under about 100 nanometers in at least one dimension. Small particles can fill microscopic defects in enamel, and most of the remineralization research uses the nano form.
- Micro hydroxyapatite has larger particles. Some brands choose it out of caution about nanoparticles. It still polishes and supports the surface, but there's less research on its remineralizing effect.
- Dual-particle formulas combine sizes, so small particles reach early lesions and larger ones coat the surface.
See safety below for the nano debate.
3. The other toothpaste ingredients
Look at the first few ingredients, because they make up most of what goes into your oral care. In most toothpastes, natural or not, they're water, glycerin or sorbitol, and an abrasive like silica. A toothpaste built around its actives will list hydroxyapatite and other functional ingredients near the top. Glycerin is a filler base; whether it slows remineralization is debated, but it means much of the tube isn't doing much.
4. No SLS
Sodium lauryl sulfate is the foaming detergent in most toothpaste. It can irritate gums and is linked to mouth ulcers in sensitive people. Most hydroxyapatite toothpastes are SLS-free, but check.
5. Supporting ingredients
- Xylitol reduces the bacteria behind cavities, so less acid attacks the enamel hydroxyapatite is repairing. See hydroxyapatite and xylitol toothpaste.
- Baking soda raises mouth pH and lifts surface stains with low abrasion.
- Gum-supporting ingredients like hyaluronic acid matter if you have sensitivity from receding gums.
6. Low abrasion
You're trying to add mineral, not scrub it away. Avoid gritty whitening formulas, especially if you have sensitivity.
How popular hydroxyapatite toothpaste brands compare
All details below come from each brand's own website as of October 2026. Formulas change, so confirm on the current label before you buy.
| Toothpaste | Hydroxyapatite (as stated by the brand) | Fluoride-free | SLS-free | Notes |
|---|---|---|---|---|
| TranscenDental | 10% nano-hydroxyapatite, two particle sizes (60nm and 200nm) | Yes | Yes | Also 2% theobromine; xylitol is the #2 ingredient; no glycerin or silica; glass jar, 60g for $25 |
| Dr. Jen Premium | 10% nano-hydroxyapatite | Yes | Yes | $18.50 per tube; Dr. Jen also makes a 10% formula with fluoride |
| Lumineux | 10% nano-hydroxyapatite | Check label | Check label | Positioned as a whitening toothpaste |
| Risewell (Original) | Micro-hydroxyapatite, 10% | Yes | Yes | Contains glycerin and xylitol; $12 for 3.4 oz. Its PRO line adds nano-hydroxyapatite |
| Davids Sensitive | nanoXIM nano-hydroxyapatite; percentage not stated | Yes | Yes | About $11 for 4 oz |
| Boka | Nano-hydroxyapatite; percentage not disclosed ("proprietary") | Yes | Yes | From about $12 per tube; many flavors |
The biggest difference between these brands is transparency. Three tell you they use 10% nano-hydroxyapatite; others don't disclose the amount. Price per ounce varies a lot too: tube brands are cheaper per ounce, while ours costs more because of the concentration of actives and the glass jar.
Which hydroxyapatite toothpaste is best for you
Best if you want a disclosed 10% nano-hydroxyapatite formula
Choose a brand that states 10% nano-hydroxyapatite in the finished product, such as TranscenDental, Dr. Jen or Lumineux.
Best for sensitive teeth
Look for nano-hydroxyapatite at a meaningful dose, low abrasion and no SLS. Sensitivity usually improves within two to four weeks of twice-daily use. See does remineralizing toothpaste work?
Best for gum health and receding gums
Most hydroxyapatite toothpastes focus on teeth only. If your gums are a concern, look for added ingredients for gum tissue such as hyaluronic acid and antioxidants. That's the gap we built TranscenDental to fill; see periodontal toothpaste.
Best if you're cautious about nanoparticles
Choose a micro-hydroxyapatite toothpaste such as Risewell's Original. You trade some remineralization research for peace of mind.
Best for whitening
Hydroxyapatite brightens by smoothing enamel, not bleaching it. A formula combining hydroxyapatite with gentle stain removers like baking soda works well. See natural whitening without peroxide.
Best on a budget
Tube brands like Boka, Davids and Risewell's Original cost less per ounce. Just know that some don't disclose how much hydroxyapatite they contain.
Hydroxyapatite vs. fluoride toothpaste
Fluoride has decades of evidence for preventing tooth decay and is still the standard in conventional oral care. It works by forming fluorapatite, a more acid-resistant mineral, on the enamel surface. Hydroxyapatite works by supplying the mineral enamel is made of.
The clinical evidence for hydroxyapatite has grown quickly. The adult trial above found it was not inferior to fluoride for cavity prevention, and similar results have been reported in children. People choose a fluoride-free toothpaste with hydroxyapatite for several reasons: they prefer to avoid fluoride, want a toothpaste that's safe if swallowed, or have children who swallow toothpaste. Some brands now offer both ingredients in one formula. If you have a high risk of cavities, talk to your dentist about which is right for you. For the full head-to-head, read hydroxyapatite vs fluoride: what the research shows.
What I brush with every day
10% nano-hydroxyapatite, organic birch xylitol and 2% theobromine in a probiotic herbal ferment. No fluoride, SLS or glycerin.
Hydroxyapatite toothpaste for children
Hydroxyapatite is popular with parents because kids swallow a lot of toothpaste, and hydroxyapatite is safe to swallow in the small amounts used for brushing. Many brands make kids' versions with milder flavors and no foaming agents. For children, use a rice-grain smear under age three and a pea-sized amount after that, supervise brushing, and check with your pediatric dentist, especially if your child has had cavities. Our toothpaste contains xylitol, so like any xylitol product, keep it away from dogs.
Is hydroxyapatite safe? What to know about nano-hydroxyapatite toothpaste
Hydroxyapatite is the same mineral as your teeth and is considered safe, including if small amounts are swallowed, which is one reason it's popular for families. The main debate is about nano-sized particles. In Europe, the EU's Scientific Committee on Consumer Safety reviewed nano-hydroxyapatite and concluded it is safe in toothpaste up to 10% when the particles meet specific requirements, including a rod shape, rather than banning it. Nano-hydroxyapatite toothpaste has also been sold in Japan since the 1980s. More in is nano-hydroxyapatite toothpaste safe?
If you'd rather avoid nanoparticles altogether, micro-hydroxyapatite is a reasonable alternative.
How to use hydroxyapatite toothpaste for best results
- Brush twice a day for two minutes with a soft brush.
- Use a pea-sized amount for adults.
- Spit, but don't rinse with water, so the minerals stay on your teeth longer.
- Avoid eating or drinking for about 30 minutes afterward.
- Give it time: smoothness often improves in a week or two, sensitivity in two to four weeks.

Frequently asked questions
Which hydroxyapatite toothpaste brand is best?
The best hydroxyapatite toothpaste states its concentration (around 10% nano-hydroxyapatite is the benchmark), is SLS-free and low in abrasion, and fits your goal, whether that's sensitivity, whitening or gum health.
What percentage of hydroxyapatite should toothpaste have?
Many studies use about 10% nano-hydroxyapatite. Lower amounts may still help, but you can't compare products that don't disclose their concentration.
Is nano hydroxyapatite better than micro?
Nano-hydroxyapatite has more research behind it for remineralization because its small particles can fill tiny enamel defects. Micro-hydroxyapatite is an option if you prefer to avoid nanoparticles.
Is hydroxyapatite toothpaste better than fluoride?
Trials show nano-hydroxyapatite toothpaste can be comparable to fluoride for preventing cavities. Fluoride has a longer track record. Hydroxyapatite is the leading choice if you want fluoride-free toothpaste.
Can I use hydroxyapatite toothpaste every day?
Yes. It's designed for twice-daily use, and it's safe if small amounts are swallowed.
Does hydroxyapatite toothpaste whiten teeth?
It makes teeth look brighter by smoothing and filling the enamel surface, but it doesn't bleach. Results are usually subtle and gradual.
What I brush with every day
