Grin Natural is a leading New Zealand oral care brand creating natural, sustainable alternatives for healthier people and a healthier planet. Featured by Forbes, Entrepreneur, The Today Show, and Allure, we make oral care that truly cares. We focus equally on what we leave out and what we put in. Our toothpaste is free from harsh chemicals, SLS, added sugar, preservatives, and artificial additives — instead powered by New Zealand-sourced ingredients like manuka oil, propolis, and organic sea salt. Clinically proven to combat common oral bacteria, Grin is trusted by dental clinics and stocked in major supermarkets nationwide. In 2018, we launched New Zealand’s first eco-friendly toothbrushes and floss picks, made from renewable or recycled materials like corn starch and 100% recycled plastic. These smart, planet-friendly designs have earned us the #1 Kids Toothbrush on Tmall and TikTok in China, and the #1 Floss Picks in New Zealand grocery. Now available in 7,000+ stores across nine markets, our growth is rooted in community impact. Through our Share A Grin initiative, we've donated over 2 million toothbrushes and brushing charts to children in need globally. We’ve also created engaging educational tools — like the I Like Brushing pop-up book and 21-Day Brushing Challenge Kit
