Key Active Ingredients:

Infused Manuka Oil Extracts

The incredible healing powers of Manuka have long been recognised by New Zealand Maori, who for centuries have utilised this native shrub in treating a range of health conditions. 

Natural Propolis Extracts

Bees are genius. As well as providing us with delicious honey (and, you know, keeping nature ticking) they also make propolis - a gloopy substance that since ancient civilisation has been recognised for its medicinal benefits. We've included propolis specifically for its antiseptic cleansing properties, just what you want in a toothpaste then.

Organic Sea Salt

Ever wondered why dentists suggest rinsing with saltwater after a dental procedure? The alkaline nature of sea salt increases the pH balance of your mouth, creating an environment that bacteria really, really hate. The sea salt we’ve put in Grin is certified organic, so it retains more of the good stuff such as calcium, magnesium, silicon, phosphorus and iron.


Directions for use:
For best results - brush at least twice a day after meals.

Warning: Propolis may cause severe allergic reactions. If irritation or swelling of the mouth or throat occurs, discontinue use and consult a healthcare practitioner.

You might notice that Grin Cool Mint toothpaste doesn’t taste the same as other mainstream toothpaste brands that rely on artificial sweeteners and flavours to create a sweet, minty taste. You may also find it doesn’t foam as much as other toothpastes that contain SLS (the same chemical found in detergents and shampoo). Grin Cool Mint toothpaste is 100% natural and uses the natural sweetness of peppermint and fennel to provide a gentle flavour that doesn’t compromise on freshness. Try Grin for a week and we’re sure you will love the natural taste and long lasting fresh mouth feel!
