You’ve probably heard us talk a lot about hydroxyapatite, the superstar ingredient that helps rebuild enamel, reduce sensitivity, and keep your smile strong. But what most people don’t realize is that not all hydroxyapatite is created equal. And that difference? It matters—a lot. Most toothpastes use hydroxyapatite particles that are far too large to get into the places they’re needed most—like the tiny dentinal tubules inside your teeth that lead to your nerves (aka the source of that painful sensitivity). At Wellnesse, we use a micro version that’s just the right size: 1–5 μm. That means it can actually reach the inner layers of your teeth, fill in weak spots, and start the natural remineralization process right where it counts. Too big, and it’s just rinsed away. Too small (like nano particles), and it could absorb where you don’t want it—like crossing the blood-brain barrier (BBB). We like to think of ours as the Goldilocks of toothpaste ingredients: just right. With Wellnesse, you’re getting safe, effective, tooth-strengthening care with real science behind it—and none of the questionable stuff. ✔️ No fluoride ✔️ No sulfates ✔️ Just better oral health, backed by research Ready to see the difference the right hydroxyapatite can make?
