Grin Whitening Toothpaste is our strongest mint-flavoured toothpaste. You might notice that it 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 up as much as other toothpastes that contain SLS (the same chemical found in detergents and shampoo). Grin Whitening 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 it for a week and we’re sure you will love the natural taste and long lasting fresh mouth feel!
