Hydroxyapatite toothpaste has become one of the most exciting innovations in modern oral care. It works by restoring the same mineral your teeth are naturally made from, helping to strengthen enamel, reduce sensitivity, and support remineralisation.

But if you’ve started researching hydroxyapatite, you’ve probably noticed there are two types used in toothpaste:

• Nano hydroxyapatite

• Micro hydroxyapatite

So what’s the difference — and which one is better for your teeth?

In this guide we’ll explain nano vs micro hydroxyapatite, how they work, and why many modern oral care brands are choosing micro hydroxyapatite toothpaste.

Many oral care products use “aroma” or artificial flavour systems — proprietary blends designed primarily for taste and sensory impact.

We take a different approach.

At Truthpaste, our flavours aren't just flavours, they're functional.

Our citrus flavour comes from sweet orange and lemon essential oils, selected not only for their clean, fresh profiles, but also for oral health benefits.

Because every ingredient in our formulas has to earn its place.
