🆕 Whitens Teeth, Strengthens Enamel & Protects Gums 💫
As we age, enamel naturally thins and weakens — which is why stains set in more easily, teeth look more yellow, and our gums get more sensitive.
That's why we rebuilt our best-selling Teeth Whitening Powder to do more. Now it whitens teeth, strengthens enamel, and protects gums — in the same 2-minute routine you already know and love.

Pick any 3 products from the Deal Builder below and get 1 free. Include a Mint Powder in your order and you'll also get a FREE Strawberry Powder on us to celebrate the launch of our new formula.
Father's Day Sale FAQs
No code needed. Just add a Mint Whitening Powder to your cart, and we'll automatically include a FREE Strawberry Powder with your order. Both arrive together.
Our Whitening Powder is now a 3-in-1 formula. It whitens teeth, strengthens enamel, and protects gums — using three new ingredient pairs:
- Hydroxyapatite & Vitamin E — strengthen enamel and soothe gums
- Papain & Bromelain — natural enzymes from papaya and pineapple that dissolve deep-set stains from coffee, tea and wine
- Pentasodium Triphosphate & Calcium Carbonate — gently lift surface discolouration, leaving teeth smooth and dentist-clean
We've also enhanced both flavours of the Powder — the Mint formula has been upgraded, and we've added a brand new Strawberry option. Same 3-in-1 formula in both — only the flavour is different.
Yes. Both Mint and Strawberry use the exact same new & improved 3-in-1 formula. The only difference between them is the flavour.
