Dentist-Approved Teeth Whitening Powder

There are two ways to use it. Brushing with the powder separately will bring you the fastest results — but if you're short on time, you can apply both together in one brushing.

Before Regular Toothpaste (Recommended): Lightly dampen your toothbrush, dip it into the Powder, and brush for 2 minutes. Rinse, then follow up by brushing again with your regular toothpaste.

Combine With Regular Toothpaste: Lightly dampen your toothbrush and dip it into the Powder. Squeeze your regular toothpaste straight over the top, then brush as normal for 2 minutes.

Use it daily for the first 14 days — that's when the heavy built-up stains and plaque start to lift. After that, twice a week is enough to maintain your results. Used that way, each jar lasts around 6 months, working out at roughly €0.38 per use.

The powder doesn't replace your toothpaste — they do two different jobs. Your toothpaste handles daily hygiene; the powder lifts the stains it leaves behind.

1 in 3 of our customers said the same thing before they bought — most of them after years of whitening toothpastes that changed nothing.

Dermatest® in Germany clinically tested the formula and awarded it their 5-star seal of approval. 95% of participants had zero sensitivity.

The Independent named it the best whitening product on the UK market in 2023, and again in 2024 — no other product has won that twice.

There are over 8,500 reviews on Trustpilot rated 'Excellent', and over 2 Million+ customers have used it.

Find out for yourself why it works.

Yes — about 1 in 4 of our new customers have never used any teeth whitening product before MySweetSmile.

The Teeth Whitening Powder is the easiest entry point into whitening because it adds 2 minutes to a routine you already have. You don't need trays, strips, gels, or appointments. You don't need to give up your toothpaste — you use the powder first, then brush as normal with regular toothpaste.

It's also one of the gentlest ways to start. There's no peroxide, no bleach, and no harsh chemicals. 95% of clinical trial participants reported zero sensitivity, and 100% reported zero gum irritation.

If you've been put off whitening because you heard it was harsh or painful, this is the formula designed to disprove that.

No. Most whitening products cause sensitivity because they use peroxide to bleach the enamel. This formula doesn't contain any peroxide at all.

Instead, it uses Hydroxyapatite to remineralise and strengthen your enamel — the surface layer that, when worn down, is what exposes the nerves underneath and causes sensitivity in the first place. Strontium Chloride then forms a protective barrier over the nerve endings, and Vitamin E soothes the surrounding gum tissue.

In our Dermatest® clinical trial, 95% of participants reported zero sensitivity, and 100% reported zero gum irritation — including people who already had sensitive teeth going in.

If your teeth are generally quite sensitive to things like cold drinks or ice cream, we'd recommend pairing the powder with our Enamel Care Serum. It repairs and strengthens enamel overnight.

Yes, and older teeth are actually where it tends to work best.

As you age, your enamel naturally thins and absorbs more staining from everything you eat and drink over the years. That yellowing looks permanent, but it isn't — and the powder lifts it without being abrasive, so you're not stripping enamel you can't get back.

It works on the yellowing that comes with age first and foremost, alongside the stains our customers mention most: coffee, tea, red wine, smoking and vaping — even berries, curries and sauces.

About 14% of our customers said they nearly didn't buy because they assumed it wouldn't work at their age. It does.

If your enamel is on the thinner side, our Enamel Care Serum remineralises and strengthens it overnight.

In an October 2024 clinical study by Dermatest®, 35% of users saw a visible difference within 7 days, and 65% within 14 days.

We recommend using the powder daily for the first 14 days, as that's when the accumulated staining starts shifting. After that, twice a week is enough to prevent new stains from settling back in.

Both flavours use exactly the same formula and deliver the same results. The only difference is the taste. We added the Strawberry Powder because a lot of customers asked for a non-mint option, so it really just comes down to which flavour you prefer.

Yes, it's completely safe for all dental work. The powder won't change the colour of artificial teeth, but it keeps them clean and smooth. And by keeping your surrounding natural teeth bright, your smile looks consistent and even overall.

For children, we recommend it for ages 12 and older.

Our formula combines three powerful ingredient pairs, each doing a different job:

Hydroxyapatite & Vitamin E — strengthens enamel and soothes gums, so you get whiter teeth without the sensitivity.

Papain & Bromelain — natural enzymes from papaya and pineapple that dissolve the deep-set yellowing that builds with age, plus stains from coffee, tea and wine.

Pentasodium Triphosphate & Calcium Carbonate — gently lift surface discolouration, leaving teeth smooth and dentist-clean.
