Pairs well with

Grin Pro Microbiome Care Toothpaste takes a different approach to your daily brush: instead of stripping everything, it works with your mouth's natural ecosystem. Micro-hydroxyapatite — the same mineral your enamel is made of — supports everyday enamel care, while a blend of postbiotics (inactivated Lactobacillus strains) helps maintain a balanced oral environment. Xylitol and New Zealand mānuka (Leptospermum scoparium) leaf oil round out the formula, with spearmint and peppermint oils leaving breath feeling genuinely fresh.

Made in New Zealand by B Corp certified Grin, this fluoride-free paste skips SLS, artificial sweeteners, colours and preservatives, using a gentle coconut-derived cleanser and palm-free glycerin instead. It's a smart everyday choice if you're curious about microbiome-friendly oral care but don't want to give up a clean, minty finish. 113g tube.

FAQ

▸ What are postbiotics, and why are they in a toothpaste?
Postbiotics are inactivated (non-living) beneficial bacteria — here, Lactobacillus strains. Because they don't need to stay alive, they're shelf-stable in a toothpaste. Grin includes them to help support a balanced oral environment as part of your daily routine.

▸ What is micro-hydroxyapatite?
Hydroxyapatite is the mineral that makes up most of your tooth enamel. The micro-sized form used here supports everyday enamel care and gives the paste a gentle polishing action, without harsh abrasives.

▸ Is this toothpaste fluoride-free?
Yes — there's no fluoride in this formula. If your dental professional has recommended a fluoride toothpaste for you, this isn't a substitute for that advice. Your dentist is the best person to ask what suits your routine.

▸ Does it contain SLS or artificial additives?
No. It's free from SLS, artificial sweeteners, colours and preservatives. It foams gently with lauryl glucoside — a palm-free cleanser derived from coconut — and is sweetened with xylitol.

▸ What does it taste like?
Fresh mint. Spearmint, peppermint and menthol, with New Zealand manuka leaf oil in the formula. It finishes clean and mild, without the harsh burn some conventional pastes leave behind.

▸ Is it suitable for kids?
It's formulated as an adult toothpaste and isn't recommended for children under 6. Grin makes dedicated kids' formulas — browse our kids' range, or ask your dental professional what's right for your child.

▸ Who makes Grin, and where is it made?
Grin is a B Corp certified oral care brand based in New Zealand, where this toothpaste is made. The range uses sustainably sourced, palm-free ingredients. This tube is 113 g (4.0 oz).
