desertcart.com : Nudge 10% Nano Hydroxyapatite Toothpaste, Enamel Friendly Advanced Clean, Fluoride Free & SLS Free, Watermelon, 4.5 oz : Health & Household

Review: Loving that toothpaste! - It comes out clear, foams a bit with a minty herbal taste (low intensity), takes care of dry mouth, and has the correct type of Nano Hydroxyapatite content - at the right amount. It is gentle for the mouth, and it does make your teeth whiter over time. I am reordering!
Review: Not minty, not disgustingly sweet, just a great flavor tooth - I have systemic scleroderma and one of the many problems that come along with that is brushing my teeth. Regular toothpaste burns my mouth, kids toothpaste is so sweet it's disgusting, and I'm trying to avoid fluoride because I've been doing research on hydroxyapatite toothpaste. I've tried a few others from Ollie, Dr squatch.... And the mint is just too much for me. I got this toothpaste today. I love it! It has an amazing foam that just makes my mouth feel so clean and the taste was wonderful. It's a subtle watermelon flavor not sweet and no mint. I'm actually looking forward to the next time I brush my teeth. It's been about an hour My mouth feels wonderfully clean and fresh my breath is great.. I can't wait to try the other flavors but for now watermelon is superb! Thank you so much for making a toothpaste for adults that those of us with medical issues that affect our mouths can use. I will be telling my support board people about this toothpaste

## Features

- NUDGE 10% NANO HYDROXYAPATITE FORMULA, ALWAYS: Nudge toothpaste has always been formulated with 10% nano-hydroxyapatite. Our original tubes followed a minimalist design and did not display the percentage on the label. We heard your feedback. Future Nudge tubes will clearly show “10% nano-hydroxyapatite” on every tube. The formula inside current tubes is unchanged and identical.
- FRESH WATERMELON FLAVOR EXPERIENCE: A light, refreshing watermelon profile delivers a clean, smooth taste that feels modern and enjoyable without harsh menthol or overpowering sweetness. Designed for people who prefer a non-mint, fruit-forward alternative to traditional toothpaste flavors.
- CRAFTED WITH 10% NANO HYDROXYAPATITE: Nudge is formulated with nano-hydroxyapatite inspired by the natural structure of tooth enamel. The rod-shaped particle design is engineered to interact efficiently with tooth surfaces, delivering a smooth, refined brushing experience and a modern alternative to traditional toothpaste formulations.
- CLEAN, FLUORIDE-FREE NUDGE FORMULA: Nudge toothpaste is fluoride-free and made without SLS, parabens, artificial colors, or unnecessary fillers. Designed for consumers who value clean ingredients, gentle formulations, and premium oral care without harsh additives.
- LOW-ABRASION DAILY PERFORMANCE: Nudge uses a carefully balanced silica system that cleans effectively with a gentle feel on enamel and gums. Suitable for daily use and for those seeking a non-aggressive toothpaste experience.

### ⭐⭐⭐⭐⭐ Clean, Fresh, Smooth.
*by K***E on February 16, 2026*

I recently heard of Hydroxyapatite and the benefits it offers. I have purchased 3 brands and four different flavors to compare. This natural mint from nudge is the front runner so far. Wholesome ingredients, no weird mouth feel or funky aftertaste. It tasted fresh, no burn, and a smooth clean feeling mouth. I like the packaging too. I'm curious to see if there is a difference in my next hygiene appointment.
