This teeth whitening powder gave me ‘a brighter smile’ in just two weeks

As far as teeth whitening treatments go, this powder perked up my pearly whites

Between daily coffees, the occasional glass of red wine, and a long-standing inability to remember a straw, it’s little wonder teeth whitening has become a constant in my beauty regimen. In an age where cameras are unforgiving and smiles are endlessly zoomed in, even subtle discolouration can feel more noticeable than it once did.

The market hasn’t exactly made things simpler. From whitening toothpastes and on-the-go pens to full LED kits promising a brighter smile in a single session, at-home whitening has never been more accessible – or more confusing. Some formulas deliver quick wins, others demand weeks of commitment, and many rely on ingredients I’d rather avoid altogether.

That’s what led me to MySweetSmile’s teeth whitening powder. With a gentler approach and a pared-back ingredient list, it stood out in a sea of peroxide-heavy options. I put it to the test to see whether it could genuinely lift stains without the usual compromises and it’s since become a permanent fixture on my bathroom shelf. Here’s why.

How I tested

To get a fair idea of how well the product performed, I tested it over several weeks while following the brand’s guidance as closely as possible. I noted various factors in my testing process, from value for money to ease of use. You can find a full list of my review criteria further down this page.

What immediately caught my eye about MySweetSmile’s teeth whitening powder is it’s approved by dentists. A predominant concern of mine when it comes to teeth whitening treatments is the negative effect it can have on teeth, so to have this professional backing instantly set my mind a bit more at ease.

Being 100 per cent fluoride- and peroxide-free, it has a non-abrasive nature, with the active ingredients including pentasodium triphosphate and calcium carbonate to tackle those dark stains that settle on our pearly whites.

The brand claims its teeth whitening powder helps remove built-up stains, yellowing and plaque caused by food, drink and even smoking. It makes sense as teeth/oil pulling (often with coconut oil or bicarbonate of soda) is a common method to remove colouring that has accumulated on teeth, so I was keen to put this method to the test.

Inundated with whitening strips and now the growing-in-popularity LED devices, I thought the powder might be messy to use, in comparison. However, due to the size of the tub and the fact that you wet your toothbrush before dipping it into the powder, it stays intact in the tub.

The process involves brushing for four minutes (before brushing your teeth with your regular toothpaste), so it is understandable that, for some, this might be tiresome. However, I found it to be an easy treatment to integrate into my nighttime skincare and oral hygiene routine, so I didn’t find it to be a huge fuss. Plus, many strips and LED devices require you to keep the products on your teeth or inside your mouth for that amount of time or longer – so this was not a bother at all. Furthermore, the treatment is recommended twice a week, as opposed to daily or for a few consecutive days.

A key factor when testing was sensitivity, as I’ve had issues with that when testing strips and other teeth whitening treatments. Luckily, there were no issues of sensitivity with My Sweet Smile’s powder – thanks to the inclusion of strontium chloride.

I actually noticed a slight difference in discolouration on some of my more stubbornly stained teeth (the canines) within a week of using the treatment, but noticed a brighter smile overall after a couple of weeks. The fast result and ease of use of the powder made me feel I could continue using this treatment whenever I felt the need for a natural glow-up.

Your questions about teeth whitening powder answered

What’s the best teeth whitening powder?

I’m fully sold on MySweetSmile’s teeth whitening powder. Not only did it deliver fast results (within two treatments), it didn’t create any issues regarding sensitivity.

While there are some tempting strips and LED devices on the market right now that might bring about a more dramatic result, the combination of a bright and white smile plus no irritation meant I could see myself using this product long-term in my beauty and oral hygiene routine.

What’s more, due to the powder application, this treatment is easy to take on trips, ensuring you can keep up with your teeth whitening treatment whenever you like.

How to use teeth whitening powder?

Different powders and brands will all come with their own instructions. Generally, steps will involve dipping a damp toothbrush into the powder and brushing your teeth for the recommended time, usually around four minutes. After this, you’ll rinse thoroughly and use the treatment one to two times per week, depending on the brand’s guidance.
