FAQs

What makes Grin different from other natural toothpastes on the market?

Our toothpaste has a couple points of difference; it’s 100% New Zealand made and we source New Zealand ingredients where possible, all Grin toothpastes contain three key active ingredients to care for your whole mouth and Grin is the only natural toothpaste that you can find in dental clinics nationwide.

What will I notice when I change from mainstream toothpaste to Grin?

Most mainstream toothpastes rely on artificial sweeteners and flavours to create the overly sweet and minty taste that people have become accustomed to. Grin uses the natural sweetness of peppermint and fennel to provide a gentle flavour that doesn’t compromise on freshness. When you try it for the first time you might find it a bit different, however if you continue using Grin for a week you, your taste buds will adjust and fall in love with Grin!

Is it safe for kids to swallow Grin toothpaste?

All our toothpastes are natural and are free from harmful ingredients. Our fluoride free kid's options 'Strawberry' and 'Orange' are safe if swallowed by your little brusher. Our with fluoride 'Berry-licious' option, kid's should avoid swallowing and spit out excess toothpaste after brushing.

Why does Grin have a coloured stripe on the bottom of the toothpaste tube?

Toothpastes have four different stripe colours. The coloured squares on the bottom of toothpaste tubes have nothing to do with the product’s content. They are instead an artifact of manufacturing process, and are known as colour marks, printed marks or eye marks. During the manufacture and packaging process these stripes allow high-speed machinery to recognise where the packaging needs to be folded or cut.
