    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.


    Calcium Carbonate, Glycerine (Palm-free from Rapeseed), Aqua (Water), Xylitol, Lauryl Glucoside (Palm-free from Coconut), Chondrus Crispus (Carrageenan) Gum, Xanthan Gum, Foeniculum Vulgare Dulce (Fennel) Extract, Menthol, Spearmint Flavour, Clove Flavour, Propolis Cera (Propolis) Extract, Copper Chlorophyllin, Peppermint Oil, Organic NZ Sea Salt, Leptospermum Scoparium Oil - Manuka Oil Pure

  • Sodium Lauryl Sulphate (SLS, a chemical foaming agent used by many big brands)
  • Artificial Preservatives (Edta, Formaldehyde, Parabens Etc.)
  • Artificial Colors, Flavors Or Fragrances
  • Propylene Glycol
  • Artificial Sweeteners Or Saccharin
  • 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 flavors 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 flavor 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!


    I'm pregnant, is it harmful for me to ingest Grin toothpaste while brushing my teeth?

    Not at all! Grin toothpaste is completely safe for pregnant women to use as it is made from of natural and safe ingredients.


    Is Grin suitable for people who suffer from a dry mouth?

    Together with its key ingredients, Grin natural toothpaste also contains the amino acid betaine. Studies suggest that the use of a detergent-free, betaine-containing toothpaste (such as Grin) may provide relief from the symptoms of dry mouth.


    Why does Grin not contain any SLS?

    SLS (Sodium Lauryl Sulfate) is a common component of standard toothpastes. This chemical compound does not actually clean teeth—its sole purpose is to produce foam, which gives the impression of cleaning. SLS is commonly be found in other foaming products, such as car wash detergents, toilet cleaning detergents, and shower gels. For some people exposure to SLS causes canker sores and mouth ulcers.


    Is Grin toothpaste gluten free?

    All Grin toothpastes are gluten free (as tested by an independent laboratory). Our products do contain 'Potassium Olivoyl Hydrolyzed Wheat Protein' however laboratory testing shows that gluten is undetected in all Grin toothpastes. Please email if you wish to obtain a copy of the testing certificate. 


    Does Grin toothpaste contain microbeads?

    Grin toothpastes do not contain microbeads.


    Do Grin toothpastes contain any GMO ingredients?

    There are no GMO ingredients in Grin toothpastes.


    Does Grin test on animals?

    Our products are not tested on animals. Our kids toothpastes are vegan friendly, whilst our Cool Mint and Whitening toothpastes are suitable for vegetarians as they contain Propolis. Propolis is a sticky substance that bees make from saliva, beeswax and tree sap to block up unwanted spaces in the hive. Our Propolis is gathered in a sustainable way without harm to bees.


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

    Toothpastes have four different stripe colors. The colored 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 color marks, printed marks or eye marks. During the manufacture and packaging process these stripes allow high-speed machinery to recognize where the packaging needs to be folded or cut.


    Grin's Toothbrushes

    What’s the benefit in using Grin toothbrushes?

    ALL our toothbrushes are eco-friendly. Our brush handles and toothbrush packaging are 100%biodegradable. This means they are able to break down in a good home / commercial compost within 12-24 months. Standard plastic toothbrushes take on average 300+ years to break down inland fill.


    What’s the difference between Bamboo and corn-starch?

    Preference. We developed our bamboo brush 3 years ago and is now extremely popular. However, some people don’t like the texture of the wood so that’s why developed a new eco-friendly alternative using corn-starch.Bamboo being a natural wood can also be susceptible to mould if left in water or damp areas. Our corn-starch toothbrushes are 100%mould proof.


    I’ve had a bamboo brush before and all the bristles fell out? 

    Can you recall if it was a Grin Bamboo brush? Since we launched ours, there are now many companies doing them. We always get positive feedback stating that our bristles hold well and don’t fall out in your mouth.


    What are the bristles made of?

    PBT (polyethylene terephthalate), these are premium bristles that we use and are the most advanced in synthetic bristles. Majority of toothbrush bristles are made of Nylon and many claim they are recyclable however this is not the case.


    Why are the bristles not biodegradable?

    To be biodegradable the material needs to come from either plants or animals. The only truly biodegradable bristles available are boar (pig) hair.


    Are the brush handles home compostable?

    Both our bamboo and corn-starch handles are fully biodegradable. The bamboo will easily breakdown in a home compost or garden in approx. 12-18 months.

    Our corn-starch handles are able to break down at home, typically taking between 24-36 months, however these require a more consistent environment. This means there needs to be a good balance of temperature, moisture and oxygen present. We recommend our corn-starch toothbrushes be sent to commercial composts as this is the most effective method. There are currently only a handful of commercial composts across the country, as they’re still relevantly limited here in NZ, so customers are welcome to send them back to us through our recycling program where we send them off to a commercial plant. 


    How do I remove the bristles?

    Before putting your brush into the compost, you can remove the bristles by either using pliers, or snapping off the toothbrush head. 


    What if I don’t have a home compost?

    There are two easy options for customers who don’t have a home compost:

    Home compost services are available throughout the – For$10 per/week they will come and collect all your compostable waste and deliver it to a commercial compost facility.

    Customers can send their used brushes into the Grin Recycling Program for free


    I have an electric toothbrush, I don’t need a manual brush.

    Electric brushes are great, however it’s always handy having a manual brush on hand, especially if you’re going traveling.


    Do you do toothbrush heads for electric brushes?

    We are looking into doing eco-friendly heads for electric brushes, however these are a lot trickier. How long do your toothbrushes last?Our brushes last as long as a standard brush. People often comment on how long their Grin brush has lasted them. Regardless, you should change your brush every 3-4 months as the bristles will begin to fray and become less effective.


    Why do you infuse your brushes with Charcoal?

    We infuse our bristles with premium activated charcoal for two reasons: 1. Charcoal is a great anti-bacterial agent which helps to keep bacteria from building up on your bristles. 2. Charcoal is great at helping to remove stains off your teeth.


    Are the Charcoal-infused brushes safe?

    Yes, they are 100% safe for all ages. The reason we don’t infuse our kids’ toothbrushes with charcoal is because young kids often don’t like the dark bristles and are used to the clear ones.

This chemical compound does not actually clean teeth- its sole purpose is to produce foam, which gives the impression of cleaning SL S is commonly be found in other foaming products, such as car wash detergents, toilet cleaning detergents, and shower gels.

    To Something Better
    Back in 2013 with the surge of organic food and natural products we started to look at what's actually in toothpaste. Unable to find a toothpaste on the market without any added chemicals, we set out to make a new kind of toothpaste to treat our teeth and mouths to something better.
