A clear explanation, not marketing noise
This part is for the curious clicker, the label reader, the “hold on, what’s actually in here?” friend. We’ll show what’s in the tube, what brushing with it feels like, and why nano hydroxyapatite has dentists and science nerds talking.
What you can expect from a nano hydroxyapatite toothpaste
Nudge is built around 10% rod shaped nano hydroxyapatite and a clean, low foam base. The goal is simple. A comfortable brush, a polished finish, and a formula that feels good enough to use every day.
- Small mineral, smooth finish Nano hydroxyapatite is a mineral related to the mineral portion of enamel. In toothpaste, it is commonly used for a smooth, polished tooth surface feel after brushing.
- Polished feel Helps create a smoother tooth surface feel after brushing for a clean, refreshed finish.
- Gentle daily routine Designed for a mild brushing experience with a comfortable, low foam clean.
- Brighter looking appearance Helps lift everyday surface stains from food and drinks with regular brushing. Results vary.
- Clean and simple Minimal ingredient approach with no SLS, no added dyes, and no artificial flavoring.
Why it feels different
Most pastes chase foam and burn. Nudge focuses on texture and finish. The result is a smoother brush, a cleaner rinse, and that polished tooth feel people notice right away.
