The Hydroxi™ name is our promise to you that our products contain the highest quality ingredients to deliver the greatest possible performance.
So, when you are looking for the best toothpaste for sensitivity, whitening, enamel health, fresh breath, fighting plaque, and remineralizaiton, just ask "does my toothpaste have Hydroxi™?"
the question everyone is asking
what is nano hydroxyapatite?
We have dedicated an entire page to explaining this key ingredient of our Hydroxi™ formulation, as well as the differences between nano hydroxyapatite (nHA), micro hydroxyapatite (mHA), and fluoride.

performance not percentage focused
Many brands push high nano hydroxyapatite percentages as a selling point, using outdated research to mislead consumers. But here’s the truth: percentage alone means nothing without quality.
Some competitors pack in more hydroxyapatite, but it’s lower-grade and far less effective. More doesn’t mean better, it means cutting corners.
The real difference lies in purity, particle size, particle shape, and formulation. Don’t fall for marketing gimmicks. Demand real science. Demand better. Demand Hydroxi™.
size
Not all hydroxyapatite toothpastes are created equal. Just because a tube claims to contain “hydroxyapatite” doesn’t guarantee it has the same effective ingredients as others. Only nano-sized hydroxyapatite particles (approximately 50 nm) are small enough to penetrate dentin tubules and repair microscopic enamel cracks. Some brands use larger micro hydroxyapatite or even calcium carbonate coated with hydroxyapatite, which can be up to 100 times larger than the particle size proven to be effective. For optimal tooth remineralization and sensitivity relief, it’s essential to choose products with the right particle size and formulation.
shape
Nano hydroxyapatite (nHA) comes in various shapes, such as rods, circles, needles, and irregular forms. However, only rod-shaped nHA has been approved for use in oral care products, and has been shown to be the most effective for remineralizing enamel and repairing tooth structure.
Unfortunately, some companies use needle-shaped particles, which have raised safety concerns and are even banned in the EU due to potential risks of cell damage. For the safest and most effective oral care, it’s essential to choose products with rod-shaped nHA particles like those used in Davids Hydroxi™ formulation.
surface
For optimal effectiveness and safety, nano-hydroxyapatite (nHA) used in oral care products must be uncoated and unmodified, in line with SCCS guidelines. Coatings or surface modifications can interfere with nHA’s natural ability to integrate with tooth enamel, potentially reducing its remineralizing power.
By adhering to these strict standards, only uncoated nHA ensures that the particles work as intended, safely repairing and strengthening teeth without introducing unnecessary additives or altering their natural properties. For the best results, choose products that comply with these regulations for maximum safety and performance. Like Davids Hydroxi™.
superior performance
You'll notice we don't mention percentage anywhere when it comes to what to look for in nano hydroxyapatite products. This is because percentage is a bad metric and, more often than not, just marketing.
Having a higher percentage doesn't mean higher effectiveness.
Instead you should focus on the performance of the toothpaste based on independent lab testing.
what sets Hydroxi™ apart
Even though nano hydroxyapatite is the star of our Hydroxi™ products, to be as effective as possible, it needs to have a great supporting cast.
The true secret of Hydroxi™ is in the high quality, carefully selected, naturally sourced naturally derived ingredients we use in our proprietary formulation. These components work together with the nano hydroxyapatite to deliver unmatched performance.
lab results show the difference
independent third party testing
Davids sent new, unopened, samples of multiple leading toothpastes including Apagard Premio, Boka, Colgate Sensitive, Risewell, Sensodyne Pronamel, and Tom's of Main Sensitive along with Davids Hydroxi™ sensitive+whitening to a leading independent lab to compare results
Hydroxi™ is the clear winner
After 5 days of brushing Davids Hydroxi™ toothpaste shows the greatest improvements in remineralizing the enamel and fully occluding the dentin tubules that cause sensitive teeth. The results speak for themselves.
results by the numbers
After five days of lab testing, the samples were given a score between 1 and 5 with 1 being the highest score and 5 being the lowest. Only Davids Hydroxi™ scored a 1. The rest of the results were as follows:
Apagard - 2.06 / Boka - 3.44 / Colgate - 2.56 / Risewell - 2.06 / Sensodyne - 2.00 / Tom's of Maine - 3.39

FAQ
What is Hydroxi™
Hydroxi™ is Davids proprietary blend of nano hydroxyapatite and carefully selected, premium, naturally sourced and naturally derived ingredients, formulated for superior oral health.
how does Hydroxi™ compare to fluoride?
Unlike fluoride, Hydroxi™ is biocompatible, non-toxic, and actively repairs enamel rather than chemically hardening it. Fluoride doesn't directly replace the lost minerals, but it helps protect teeth from decay by encouraging the absorption of calcium and phosphate from saliva and other sources. This forms a protective layer of fluoridated apatite on the tooth surface. In contrast, Hydroxi™ directly replenishes lost minerals to repair demineralized areas beneath the enamel and fills tiny fissures on the enamel's surface. Additionally, its nanoparticles bind to proteins, such as oral bacteria and plaque fragments, during brushing, helping to remove them from the mouth when rinsing.
what makes Davids with Hydroxi™ different from other hydroxyapatite products?
Hydroxi™ combines the safest and most effective nano hydroxyapatite with synergistic natural ingredients to outperform competing hydroxyapatite products.
is Hydroxi™ safe for kids?
Yes, Hydroxi™ is gentle, effective, and safe for all ages, making it an ideal fluoride alternative for children.
can Davids products with Hydroxi™ whiten teeth?
Yes, Hydroxi™ gently restores enamel to a smooth, stain-free surface for a whiter, brighter smile.
how often should I use Davids toothpaste with Hydroxi™?
Brush twice daily for best results.
where can I buy Hydroxi™?
Available on Davids website, Amazon, grocery and specialty retailers.
is Hydroxi™ environmentally friendly?
Yes, Hydroxi™ is derived from natural sources (no animal byproducts) aligning with Davids commitment to sustainability and clean ingredients.
what % of nano hydroxyapatite do you use for your toothpaste products that include this ingredient?
The Scientific Committee on Consumer Safety (SCCS), the primary EU regulatory board for cosmetic safety, recommends having less than 10% hydroxyapatite for safety purposes, which is inline with Davids Hydroxi™ formulation.
It is important to note that a higher percentage does not mean better performance as not all hydroxyapatite material is the same or performs the same. Many competing hydroxyapatite toothpaste products use calcium carbonate coated with hydroxyapatite, or micro hydroxyapatite which does not remineralize the teeth or reduce sensitivity nearly as effectively as the nano material found in Davids Hydroxi, even when used at a much higher percentage.
Davids Hydrox™ toothpaste is formulated for maximum performance, not maximum percentage. Look at the lab results above to see how Davids Hydroxi™ nano hydroxyapatite toothpaste compares to competing hydroxyapatite toothpaste products.
