People complement whitening toothpaste with strawberry matcha superlatte as the superlatte offers antioxidants and gentle natural flavours that support oral health, helping to maintain a fresh, clean feeling after whitening treatments.
Enzyme Whitening Toothpaste + Nano-Hydroxyapatite combines natural fruit enzymes and a biomimetic mineral to deliver a comprehensive approach to oral care. Bromelain and papain—derived from pineapple and papaya—work together to break down plaque proteins and dissolve surface stains from coffee, tea, wine, and everyday foods. This plant-powered action reveals a visibly brighter smile without harsh abrasives.
Nano-hydroxyapatite, a mineral that closely resembles the structure of tooth enamel, helps fill in microscopic cracks and restore smoothness to the tooth surface. This makes enamel more resistant to acid erosion and future staining while reducing sensitivity. The result is stronger, glossier teeth that reflect light better—without the use of fluoride. Enzyme Whitening Toothpaste + Nano-Hydroxyapatite offers a clean, science-led solution to everyday whitening and enamel defence.

Why Grin is Healf
Enzyme Whitening Toothpaste + Nano-Hydroxyapatite uses a highly purified form of nano-hydroxyapatite that meets the strict safety standards of the Scientific Committee on Consumer Safety in Europe. The formula contains 15.5% active nano-HAp with rod-shaped particles smaller than 100 nm, designed to integrate seamlessly into the enamel structure. With an ultra-low RDA below 10, it offers effective stain removal without damaging the tooth surface. This biocompatible, paraben-free, and vegan formula supports daily use while protecting enamel and promoting long-term oral health.
Grin was founded by Tara Tan in New Zealand with a clear mission to create effective oral care without harsh chemicals. When she couldn’t find a toothpaste free from artificial additives, she spent 18 months developing one. Grin uses natural active ingredients like Manuka Oil, Propolis, and Organic Sea Salt, backed by lab testing to help combat common oral bacteria. Every product reflects a commitment to clean formulations, scientific integrity, and sustainable practices, using New Zealand-sourced ingredients. Grin offers you a healthier, natural way to care for your teeth and support long-term oral health.

I personally think that this is a great toothpaste. It has a regular minty flavour that isn't too intense or too weak, and leaves my teeth feeling strong and clean!

Thank you Grin!
One of the best toothpastes I’ve ever used! I don’t think I can go back to any of the big brands. It leaves my teeth feeling stronger and noticeably whiter! Even my colleague commented that my teeth look brighter, which was amazing to hear. I also love that it contains NHA, especially as my dentist has been recommending it.
