DAY 1
You'll get that dentist-clean feeling, the type you'd only get after leaving the hygienist's office — as the powder lifts away the built-up plaque that regular brushing leaves behind.
DAY 7
You'll start to notice years of coffee, tea and wine stains visibly lifting — finally shifting the yellow stains you've simply accepted as "just part of getting older."
DAY 14
You'll find yourself smiling with confidence again — in photos with friends, at family events, and with the grandkids — with sensitivity and individual results varying, using the powder's gentle, non-abrasive formula.

INDEPENDENT CLINICAL EVALUATION
Our Teeth Whitening Powder was evaluated by Dermatest GmbH, an independent testing laboratory in Germany. The assessment was reviewed by a dentist, dermatologist and biologist.
The result: clinically measured whitening performance and a 5-star tolerability assessment.
20 participants used the powder daily for four weeks under clinical supervision. Tooth colour, plaque, gum tolerance and tooth sensitivity were assessed during the evaluation.
Beyond the clinical measurements, participants shared their honest feedback after four weeks of testing:
Your regular toothpaste supports everyday oral hygiene. Whitening powder is an additional step intended to help with surface staining; it does not replace toothpaste.
This powder does what toothpaste can't. The Fresh Mint formula is intended for surface staining from everyday habits. Its ingredient list does not include enzymes, and sensitivity or results can vary. Just dip your toothbrush into the powder, add your regular toothpaste straight over the top, and brush. It isn't another gadget or gimmick. It's the missing step in a routine you already have.
The Independent's IndyBest awards are one of the UK's most trusted product reviews, tested and judged by an independent editorial panel. TELYSI Powder won Best Teeth Whitening Product in both 2023 and 2024 — no other whitening product has ever won it twice.
Also featured regularly in The Times, Daily Mail, Mirror, HELLO! Magazine and Apple News.
We're proud to say that no other teeth whitening brand in the world has more reviews at a higher rating than TELYSI.
Over 2 Million+ customers have used TELYSI — and they're smiling with confidence again. Many of them arrived sceptical, spent time reading the reviews below, and decided thousands of people couldn't all be wrong.
See what they say for yourself below.
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.
Find out for yourself why it works.
Yes — about 1 in 4 of our new customers have never used any teeth whitening product before TELYSI.
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.
If you've been put off whitening because you heard it was harsh or painful, this is the formula designed to disprove that.
Sensitivity is possible with whitening products. This formula doesn't contain any peroxide at all.
Instead, it's designed to whiten while protecting the enamel — the surface layer that, when worn down, is what exposes the nerves underneath and causes sensitivity in the first place. Strontium Chloride forms a protective barrier over the nerve endings. Vitamin E is not listed in the Fresh Mint ingredient list.
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.
This TELYSI listing offers Fresh Mint only. The source also offers Strawberry; consult the respective ingredient lists because they are not identical.
Ask your dentist about suitability for your particular 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 ingredients, each doing a different job:
Pentasodium Triphosphate & Calcium Carbonate — break down the stain molecules sitting in your enamel and gently polish away plaque and surface debris, leaving teeth smooth and dentist-clean.
Strontium Chloride — forms a protective barrier over the nerve endings, so you get whiter teeth without the sensitivity.
Allantoin — soothes and conditions gums while the powder works.
Full Ingredient List:
Mint: Calcium Carbonate, Pentasodium Triphosphate, Menthol, Sodium Lauryl Sulfate, Sodium Saccharin, Mentha Viridis Leaf Oil (Spearmint Oil), Allantoin, Strontium Chloride Hexahydrate, Limonene.
No, the powder is fluoride-free. It's also free from peroxides, parabens, PEGs, and phthalates. You get your fluoride from your regular toothpaste, and the two are designed to work alongside each other without any overlap.
