Got Questions? Let’s Brush Up on the Answers 🔆

Think of this as a "deep clean" step right before your regular brushing.

  • Dip: Lightly dampen your toothbrush and dip it into the powder.
  • Brush: Brush gently for 2-4 minutes to lift the deep-set, porous stains that regular toothpaste misses.
  • Smile: Rinse your mouth, then brush with your normal toothpaste as usual to wash away the lifted debris.

For Best Results: We recommend using it daily for the first 14 days to lift years of built-up stains & yellowing.

For Smile Maintenance: After the first two weeks, switch to 2x per week (or as needed) to keep your smile permanently bright and stain-free.

No, they serve two different purposes.

  • Toothpaste is for daily hygiene, gum health, and cavity protection.
  • The Powder is a specialised treatment solely for lifting deep-set stains and restoring brightness.

Use the Powder first to lift stubborn stains, then follow up with your toothpaste to brush away debris, strengthen enamel, and freshen your breath.

Our clinically proven formula lifts the deep-set stains that regular toothpaste misses, including:

  • Coffee & Tea: Eliminates the dark residue from your daily brew (or two!).
  • Smoking & Vaping: Lifts stubborn nicotine and tar stains.
  • Pigmented Foods: Removes discolouration from red wine, berries, curry, and sauces.
  • Natural Ageing: Brightens teeth that have yellowed over time.

Unlike abrasive charcoal powders that scrape your enamel, our powder is 100% non-abrasive. It safely dissolves stains without damaging your teeth or causing sensitivity.

Not at all. Our formula is clinically tested and has been awarded the 5-Star Seal of Approval by Dermatest®, proving it is safe for even the most sensitive smiles.

It is 100% Peroxide-Free and enhanced with Strontium Chloride, which forms a protective barrier over nerve endings in the teeth.

If you suffer from extreme sensitivity generally (from cold drinks, ice cream, etc), we recommend pairing this with our Enamel Care Serum. It works overnight to repair enamel and stop sensitivity for good.

Just the flavour! Whether you choose Original Mint or Strawberry, you’re getting the exact same award-winning, dentist-approved formula trusted by over 1,000,000 customers.

  • Original Mint: Our signature refreshing mint for a classic, icy-fresh clean.
  • Strawberry: A sweet, fruity alternative for those who want a fresh change from traditional mint.

Both powders are 100% peroxide-free, enamel-safe, and deliver the same professional whitening results in just 4 minutes.

Strawberry was highly requested by those looking for a non-mint option, so we listened! It simply comes down to your personal preference.

Yes, it is completely safe for all dental work.

While the powder cannot change the original colour of artificial teeth (caps, veneers, bonding), it is highly effective at keeping them smooth and clean.

By keeping your surrounding natural teeth bright and stain-free it ensures your smile looks consistent and uniform.

Each tub provides up to a 6-month supply when used twice weekly.

Because the formula is highly concentrated, a little goes a long way. This makes it an exceptional value compared to single-use strips or expensive dental appointments, giving you professional-level stain removal for just pennies per treatment.

MySweetSmile’s Teeth Whitening Powder is formulated with clinically proven ingredients to lift deep-set stains and protect your teeth, without the use of harsh peroxides.

  • Pentasodium Triphosphate – A powerful stain-lifting agent that oxidises and dissolves deep-set discolouration.
  • Calcium Carbonate – Gently polishes the teeth to remove plaque and debris without damaging enamel.
  • Strontium Chloride – Forms a protective barrier over nerve endings to ensure a sensitivity-free experience.

Full Ingredients List by Flavour:

🍃 Original Mint Powder:
Calcium Carbonate, Pentasodium Triphosphate, Menthol, Sodium Lauryl Sulfate, Sodium Saccharin, Mentha Viridis Leaf Oil (Spearmint Oil), Allantoin, Strontium Chloride Hexahydrate, Limonene.

🍓 Strawberry Powder:
Calcium Carbonate, Pentasodium Triphosphate, Menthol, Sodium Saccharin, Fragaria Vesca (Strawberry) Fruit Extract, Mentha Viridis (Spearmint) Leaf Oil, Sodium Lauryl Sulfate, Beta Vulgaris (Beet) Root Powder, Carvone, Allantoin, Hydroxyapatite, Strontium Chloride, Limonene, Papain, Bromelain, Tocopheryl Acetate.

No. Our Whitening Powder is 100% Fluoride-Free.

It is also completely free from peroxides, parabens, PEGs, and phthalates.

We designed it this way so it pairs perfectly with your regular toothpaste. This ensures you get deep stain removal without interfering with your daily fluoride intake.

Yes. In fact, it is ideal for older teeth.

As we age, enamel naturally thins and absorbs decades of deep-set stains. Because our formula is 100% non-abrasive, it lifts these years of yellowing without stripping away your precious enamel layers.

For those with thin enamel, we recommend pairing the Powder with our Enamel Care Serum.

This gives you a complete solution where the powder safely lifts deep stains, while the serum works to remineralise and strengthen your enamel structure.

Our Teeth Whitening Powder is backed by clinical testing and has the Dermatest® 5-Star Seal of Approval. In an October 2024 clinical study, 65% of users noticed improvements within 14 days, with 35% reporting visible results in just 7 days.

Because of this, we recommend using the powder daily for the first 14 days to lift years of deep-set stains and yellowing.

However, whitening isn’t a one-time fix; it’s about ongoing care. Think of your teeth like a white T-shirt: it starts bright, but dousing it in coffee and food would, of course, naturally stain it over time.

You wouldn't wash a white T-shirt once and expect it to stay clean forever; your teeth are no different because enamel is porous, just like clothes.

This is why, after your initial 14-day deep clean, we suggest switching to using the powder twice a week to prevent new stains from settling and maintain your results effortlessly.

Consistency is key! Using the Powder twice a week (or daily for the first 14 days) is all you need to lift stains and achieve a whiter, brighter smile.

However, if you want to accelerate your results for a special occasion, you can pair it with our other products:
