🌿 Handcrafted in Kerikeri, New Zealand | Organic | Vegan | Fluoride-Free | SLS-Free
Our bestselling Mineralising Toothpowder is the most powerful formula in the M&M range — a unique fusion of powdered New Zealand kelp and antibacterial spices that cleans, remineralises, and whitens, naturally. One jar lasts 3+ months.
If you've struggled with tooth sensitivity or want to move beyond synthetic oral care, this is where most people start — and stay.
Why It Works
NZ Kelp (Ecklonia radiata): Rich in natural minerals that support enamel formation and actively break down dental biofilm — plaque and tartar — before they can cause damage.
Natural Baking Soda: Gently whitens, neutralises plaque acids, and freshens breath without harsh abrasion.
Organic Xylitol: Clinically supported to inhibit Streptococcus mutans — the primary bacteria behind tooth decay.
Natural Calcium Carbonate: Introduces remineralising calcium directly into your saliva environment while gently polishing enamel.
Antibacterial Spices: Cloves, cinnamon, cardamom, and star anise deliver a warm, distinctive taste with genuine antimicrobial properties.
What to Expect
The aniseed-forward flavour is unlike any conventional toothpaste — warming, spiced, and genuinely refreshing. A small dip goes a long way. Most customers notice cleaner-feeling teeth within the first week and report significant sensitivity improvement within a month.
How to Use
Lightly wet a soft toothbrush.
Dip generously into the powder.
Brush thoroughly for 2 minutes, then rinse and floss.
Value: One 60g jar = 3+ months of daily brushing. At $17 NZD, that's under $6/month for premium natural oral care.

A favorite for my very sensitive teeth, this works better for me than the commercial well known brand. Lovely taste too, although I like abit more anise, so I sometimes add more myself. I buy this regularly. Top product and my dental hygienist is amazed how clean my teeth are.

All the Maxwell and Macintyre toothpastes work really well
All the Maxwell and Macintyre toothpastes work really well, and I have improved oral health since I started using them. The flavour and consistency can vary between batches, which just reminds me that they are totally natural, with no stabilisers or emulsifiers.
