When a dentist from Hello Smile clinic says that our toothpaste means less filling work for them, we are sure we are doing the right thing. Today, the emphasis is on prevention, not repairs – and the best proof of success is that she herself uses the same toothpaste she recommends to her patients, parents, and children.

As a dentist, I'm used to reminding patients about the importance of oral hygiene. With HelloSmile toothpaste, the situation is reversed; patients come to me and tell me how brushing their teeth has become pleasant, how they feel their teeth are smoother, and how their breath stays fresh longer than before. For me, that's the strongest proof that the formula works. When people themselves want to use a toothpaste and talk about it, then you know you've got something that changes habits in practice, not just on paper.

HelloSmile is unique because it uses ingredients that are both effective and safe. Instead of harsh chemicals and abrasives, it relies on minerals and enzymes that preserve and restore enamel. It's a formula that protects long-term dental health, which is why I trust it.

Answers to all your questions

If you want fast removal of surface stains (coffee, wine, tobacco), Activated Charcoal is ideal. For an instant refresh and optical whitening before going out, use the Purple Serum. The PRO set combines an LED lamp and a special gel for longer-lasting and more intensive home whitening. Strips are a simple "all-in-one" treatment for daily use, and the Pen is the fastest option when you're in a hurry; you apply the gel and see a difference in a few minutes. For daily hygiene and a smile rich in flavors, there are our Toothpastes (watermelon, mango, mint, kiwi, pineapple, passion fruit, lemon, cola, energy drink, gummy bears, chocolate, green apple, strawberry).

All our products: Activated Charcoal, Purple Serum, PRO set, Strips, Pen, and Pastes, do not contain peroxide or harsh abrasives. They do not irritate enamel or gums, making them suitable even for those with fillings, crowns, or veneers. The Purple Serum and Pen create optical tone correction, without chemical aggression. The PRO set, Strips, and Activated Charcoal work mechanically or through mild chemistry without sensitivity. The Pastes do not contain SLS, parabens, triclosan, or microplastics, making them suitable even for teenagers and pregnant women.

Activated Charcoal: After brushing, dip a wet toothbrush into the powder and gently rub it onto your teeth for 1–2 minutes, preferably in the evening, 2–3 times a week.

Purple Serum: Brush your teeth, apply a thin layer of gel onto your toothbrush, rub for 60 seconds, and rinse. Use before an important event or daily in the evening.

PRO Set: Follow the instructions: apply the gel from the syringe onto your teeth, place the LED light for 10–15 minutes, then rinse. Repeat the treatment for 7–14 days, depending on the desired effect.

Strips: After brushing and drying your teeth, apply the strips to your upper and lower jaw and leave for 20–30 minutes, then rinse. Use once daily for 7–10 days, then once a week as needed.

Whitening Pen: Clean and dry your teeth, dispense a small amount of gel with the pen tip, apply along the stained surface, wait 2–3 minutes, wipe off any excess. Ideal before going out or a meeting.

Toothpastes: Use every morning and evening, squeeze a small amount of paste onto your toothbrush, brush for 2 minutes, and rinse. The choice of flavors matches your style: watermelon, mango, mint, kiwi, pineapple, passion fruit, lemon, cola, energy drink, gummy candies, chocolate, green apple, or strawberry.

All products (Paste, Pencil, Strips, Purple Serum, Activated Charcoal) are available in most pharmacies and drugstores nationwide.

For Activated Charcoal and Purple Serum we offer a "Whiter Teeth or Your Money Back" guarantee: photograph your smile for the first time and after two weeks of use, then send us a selfie—if there's no difference, we'll refund 100% of your payment. For the PRO set and Strips, the effect lasts up to 4 months if you follow the instructions; in case you don't see at least 2 shades of difference after the standard 14-day cycle, contact us for a refund. The Pen does not have a refund guarantee, but most users see an instant change. Toothpastes are health-approved and safe, but there is no guarantee for taste – satisfaction usually comes after the first brushing.

Yes, but pay attention to the frequency. For example, you can first use the PRO set or Whitening Strips for 7–10 days, then maintain whiteness once a week with active charcoal or a whitening pen. Purple Serum and Whitening Pen are for a quick refresh before going out, not for continuous whitening. Use toothpastes daily, choose the flavor you like. Do not combine the PRO set and Active Charcoal on the same evening—Wait 24 hours after whitening with gel/Whitening Strips before using active charcoal.

Yes. All formulas are peroxide-free, SLS-free, and free of harsh chemicals, so they do not dry out the oral mucosa or irritate the gums. The Purple Serum and Pen do not damage fillings, crowns, veneers, or bridges. The PRO set, Strips, and Activated Charcoal remove stains mechanically or through gentle enzymatic action without causing sensitivity. The toothpastes are made with natural enzymes and plant extracts, without harmful additives, so they help soothe inflamed gums.
