Not all toothpaste is created equal—and what’s inside matters more than you think. For decades, fluoride has been the go-to for preventing cavities and supporting enamel health, but it comes with its own baggage: concerns about toxicity, dosage sensitivity, and environmental impact. Enter Hydroxi™, a proprietary nano hydroxyapatite blend from Davids that flips the script on oral care, offering a clean, safe, and science-backed alternative that actually repairs enamel and relieves sensitivity, without compromise.
And now, it’s not just in their toothpaste. With the launch of Davids Hydroxi™ Mouthwash, you can extend the benefits of nano hydroxyapatite to every corner of your mouth. Paired with their beautifully packaged, metal-tubed toothpaste line (including options for sensitive teeth and kids), this is more than a clean swap. It’s a whole new standard. So what makes Hydroxi™ different? Read on to find out why this one ingredient is quietly transforming smiles, and setting a new benchmark for oral health.
What Is Hydroxi™, Really?
Hydroxi™ is Davids’ proprietary blend of nano hydroxyapatite (nHA), a mineral that makes up 97% of your tooth enamel, combined with thoughtfully selected, naturally derived ingredients. While Davids has always used nHA in their formulas, the Hydroxi™ name is now front and center, signaling the brand’s commitment to performance, purity, and transparency. In a market cluttered with “clean” claims and fluoride copycats, Hydroxi™ sets the gold standard.
This ultra-fine, rod-shaped form of hydroxyapatite is lab-tested, perfectly sized for deep enamel penetration, and biocompatible with the human body. Translation? It doesn’t just sit on the surface, it’s actively absorbed into the enamel, filling in micro-cracks, smoothing the tooth surface, relieving sensitivity, and fortifying against future damage.
Why Not Fluoride?
Fluoride has been a mainstay in dental care for 70+ years, but it requires just the right circumstances to work. It relies heavily on the calcium and phosphate in your saliva to form a protective fluorapatite layer, so if those minerals are low, its efficacy drops. Plus, getting the dosage right can be tricky. Too little fluoride? You risk decay. Too much? Dental fluorosis, skeletal issues, and potential neurotoxicity in young children.
Then there’s the environmental side. Excess fluoride in water systems can accumulate, affecting soil quality and aquatic ecosystems. As more consumers seek out effective, health-conscious alternatives, nano hydroxyapatite is emerging as a smarter, safer solution.
Nano vs. Micro Hydroxyapatite
Not all hydroxyapatite is created equal. Some companies use cheaper micro hydroxyapatite (mHA), which is too large to penetrate the enamel. Others lean on percentage-based marketing, highlighting how much HA is included, rather than how well it performs.
Davids’ Hydroxi™ line uses uncoated, rod-shaped nHA particles precisely 50 nanometers in size, which is the sweet spot for safe absorption and maximum enamel repair. This is the particle size that clinical research supports, and it’s the reason Davids outperforms many of the biggest names in oral care.
What Does It Actually Do?
In a word: everything. Hydroxi™ toothpaste strengthens and rebuilds enamel, reduces sensitivity, whitens teeth by smoothing surface irregularities, and helps remove plaque by bonding to it during brushing.
Thanks to its biocompatibility and nano size, Hydroxi™ doesn’t just sit on the surface of your teeth—it integrates into the enamel structure to rebuild from the inside out. The result is smoother, stronger, brighter teeth and long-lasting relief from sensitivity.
A Smarter Approach to Sensitivity
Most toothpaste for sensitive teeth relies on potassium nitrate, which works by dulling the nerve response to pain. But Davids takes a different route. Instead of numbing, Hydroxi™ uses nano hydroxyapatite to repair the enamel and physically block the passageways to the nerves. The result? Real, lasting relief from dental hypersensitivity and a reason to smile every time you brush. Independent lab tests show dentin tubules (the microscopic openings that cause tooth sensitivity) being visibly filled after just five days of brushing with Davids Hydroxi™ toothpaste.
