Grin Buying Guide

Grin covers several parts of an everyday oral care routine, but its toothpaste formulas aren’t all the same. The most useful place to start is with your preferred approach to fluoride, the purpose of the formula and whether you’re choosing for an adult or child. You can also view our wider natural toothpaste collection if you’d like to consider other brands.

Grin Natural Toothpaste

The everyday Grin Natural collection includes Strengthening, Freshening and Whitening Toothpaste with Fluoride, all in 100g tubes. Strengthening is positioned for customers seeking an everyday strengthening formula, while Freshening provides a freshness-focused alternative. The Whitening Toothpaste with Fluoride combines a whitening focus with fluoride, making it the clearest choice within this collection if both features matter to you.

Grin Pro Toothpaste

Grin Pro contains more specialised 113g formulations. Pro Enamel Care features nano-hydroxyapatite, while the two Pro Enzyme Whitening toothpastes let you choose between fluoride and nano-hydroxyapatite. This collection may appeal if you’re looking beyond an everyday formula and want a product with a more targeted enamel-care or enzyme-whitening focus.

Fluoride vs Fluoride-Free Grin Toothpaste

Grin offers both approaches, rather than making every toothpaste fluoride-free. Fluoride has strong evidence supporting its role in preventing tooth decay and is included in Grin Natural Whitening, Grin Pro Enzyme Whitening with Fluoride and Kids Berry-Licious. Other formulas use different ingredient approaches, including hydroxyapatite or nano-hydroxyapatite. One isn’t automatically the right choice for everyone, so consider your dental history, age and advice from your dentist when deciding.

Hydroxyapatite vs Nano-Hydroxyapatite

Hydroxyapatite is a calcium phosphate mineral naturally found in tooth enamel. Nano-hydroxyapatite is the same type of mineral in much smaller particles and appears in selected Grin Pro formulas. Particle size is only one part of a complete toothpaste formulation, so hydroxyapatite products shouldn’t be treated as identical or assumed to offer the same outcomes as fluoride toothpaste.

Grin Whitening Toothpaste

Whitening toothpastes are generally intended to address surface stains rather than bleach teeth or change their underlying colour. Grin Natural Whitening with Fluoride provides an everyday whitening formula, while Grin Pro Enzyme Whitening uses an enzyme-based approach and comes in separate fluoride and nano-hydroxyapatite versions. This makes the active formulation a more useful deciding factor than the word “whitening” alone.

Grin Kids Toothpaste

Grin Kids Strawberry Toothpaste is fluoride-free, while Berry-Licious contains fluoride. Flavour can encourage a more willing brushing routine, but it shouldn’t be the only consideration. Choose according to the child’s age, fluoride needs and dental guidance. Our broader kids toothpaste category provides more formulas if you’re comparing beyond Grin.

Grin Dental Floss

Grin Ultra Clean Coconut Oil Infused Floss comes with 30m of floss plus a separate 30m refill. Traditional string floss gives you control over the length used and can be gently curved around each tooth. If material choice is important, our broader silk dental floss collection offers a different style to consider.

Grin Floss Picks

Grin’s pick format includes Watermelon and Grape flavoured 80 packs, plus Charcoal Infused options in 40 and 80 packs. The built-in handle can be easier to manoeuvre for people who find wrapping string floss around their fingers awkward. String floss provides more flexibility around each tooth, while picks can be handy when ease of handling is the priority.

Grin Toothbrushes

Grin’s wider collection includes recycled-plastic toothbrushes, specialist bristle designs and children’s toothbrushes, although Shop Naturally doesn’t currently stock these products. If you’re putting together a child’s oral care routine, you can see the currently available toothbrushes for kids from other brands.

Compare Grin Oral Care Products

Grin offers everyday toothpaste, specialised Pro formulas, children's oral care and dental floss. The biggest differences are whether you prefer fluoride or fluoride-free toothpaste, the type of formula you're looking for and how you like to floss.

Grin Range	Options	Best For
Natural Toothpaste	Strengthening, Freshening and Whitening with Fluoride	Everyday adult brushing, with different formulation preferences
Grin Pro Toothpaste	Enamel Care and Enzyme Whitening, with fluoride and nano-hydroxyapatite options across the range	Customers looking for specialised enamel-care or whitening formulations
Kids Toothpaste	Strawberry fluoride-free or Berry-Licious with fluoride	Children's brushing, with a choice of fluoride formulation and flavour
Dental Floss	Coconut Oil Infused Floss with refill	Traditional string flossing with control around individual teeth
Floss Picks	Watermelon, Grape and Charcoal Infused	Convenient handled flossing in different flavours and pack sizes

Grin Fluoride vs Fluoride-Free Toothpaste

Grin offers both fluoride and fluoride-free toothpaste, so check the formulation rather than assuming the whole range is the same. Fluoride is a well-established ingredient for helping prevent tooth decay, while selected fluoride-free Grin products use hydroxyapatite or nano-hydroxyapatite. Your choice should take your dental needs and preferences into account, with advice from your dentist where appropriate.

Grin Natural vs Grin Pro Toothpaste

Grin Natural focuses on everyday oral care, including strengthening, freshening and whitening toothpaste. Grin Pro offers more specialised formulations, including Enamel Care with Nano-Hydroxyapatite and Enzyme Whitening in fluoride and nano-hydroxyapatite versions. Both collections are designed for regular brushing, but their ingredients and formulation priorities differ.

Grin FAQ

Is Grin an Australian brand?

No. Grin is a New Zealand oral care brand established in 2015. Shop Naturally is an Official Australian Stockist, giving Australian customers access to selected Grin adult and children’s toothpaste, dental floss and floss picks.

Does Grin toothpaste contain fluoride?

Some Grin toothpaste contains fluoride and some is fluoride-free. Natural Whitening, Pro Enzyme Whitening with Fluoride and Kids Berry-Licious contain fluoride. The range also includes fluoride-free products, including selected hydroxyapatite and nano-hydroxyapatite formulas, so the answer depends on the individual toothpaste.

What is hydroxyapatite in Grin toothpaste?

Hydroxyapatite is a calcium phosphate mineral naturally present in tooth enamel. Grin uses hydroxyapatite or the smaller-particle nano-hydroxyapatite in selected formulations. It provides a different formulation approach from fluoride, but its presence alone doesn’t make every hydroxyapatite toothpaste identical or universally equivalent to fluoride toothpaste.

Is Grin toothpaste SLS-free?

Yes, the Grin toothpaste formulations in the current Shop Naturally range are SLS-free. Sodium lauryl sulfate, usually shortened to SLS, is a foaming ingredient. An SLS-free toothpaste may produce less foam, but the amount of foam doesn’t tell you how well you’ve brushed.

Is Grin toothpaste vegan?

Vegan suitability varies between Grin formulations. Some products contain propolis, which is derived from bees, while specific products are labelled vegan. If avoiding animal-derived ingredients matters to you, use the vegan information and complete ingredient list for the individual toothpaste rather than applying one description to the whole brand.

Our Advice for Choosing and Using Grin Oral Care

Finding the right toothpaste is only part of looking after your teeth. Good brushing habits, regular flossing and choosing products that suit your individual needs are just as important. Here are a few practical tips to help you get the most from your Grin oral care products.

Choose Toothpaste for Your Dental Needs

Before choosing your favourite flavour, consider whether you prefer fluoride or fluoride-free toothpaste, along with your age, dental history and any advice from your dentist. Grin offers both fluoride formulations and hydroxyapatite alternatives, giving customers different options for their daily routine. Fluoride remains a well-established ingredient for preventing tooth decay, so discuss any uncertainty about your individual needs with your dental professional.

Don't Judge Toothpaste by How Much It Foams

If you're switching from a conventional high-foaming toothpaste, an SLS-free formula may feel a little different at first. That's perfectly normal. Foam isn't what determines how well you've brushed your teeth. Good technique, brushing for two minutes twice a day and cleaning all tooth surfaces matter much more than how many bubbles your toothpaste produces.

Understand What Whitening Toothpaste Can Do

Whitening toothpaste generally works by helping remove everyday surface stains rather than changing the natural colour of your teeth. Grin Natural Whitening and the enzyme-based Grin Pro whitening formulations take different approaches to stain removal, so check the individual product ingredients and directions. Neither should be confused with a professional bleaching treatment.

Help Children Build Good Brushing Habits

For young children, the right toothpaste and the amount used matter more than an exciting flavour. Australian dental guidance generally recommends a smear of low-fluoride toothpaste from 18 months to five years, with adult supervision, followed by a pea-sized amount of standard fluoride toothpaste from six years. Children should be encouraged to spit out excess toothpaste rather than swallow it. Check the fluoride concentration and age directions on individual Grin products, and follow your dentist's advice where your child's needs differ.

Make Flossing Easier to Repeat

The best floss is one you can use comfortably and consistently. Traditional string floss can be curved around individual teeth, while handled floss picks may make reaching the back teeth easier. Whichever format you choose, use gentle movements and avoid snapping the floss against your gums. Grin's flavoured floss picks can also make the routine a little more enjoyable.

Check Vegan Suitability Product by Product

Not every Grin product has the same ingredients. Some formulations contain propolis, which is derived from bees, while other products are specifically identified as vegan. If avoiding animal-derived ingredients is important to you, check the individual product description and ingredient list rather than assuming the entire Grin range is vegan.

Replace Worn Toothbrushes

A toothbrush with flattened, frayed or widely splayed bristles isn't doing its best work. As a general guide, replace your toothbrush every three months, or sooner if the bristles show signs of wear. Rinse it thoroughly after brushing and allow it to air dry between uses.
