AT-home teeth whitening can feel daunting, especially when there’s so much on the market.
From dodgy peroxide kits to short-term charcoal toothpastes that promise the world, it’s hard to find an affordable product that actually works.
We spent the last month testing MySweetSmile’s viral bestsellers, from teeth whitening strips to powders, to see if the hype around this British-born brand is actually justified.

Before I jump into this review, it’s important to note that you’re not going to experience dramatic, instant results with any of these products.
We all have days when we could really do with a brighter smile (I know I do), but if you’re looking for whiter teeth for a particular occasion, it’s worth putting in the legwork a couple of weeks before the big day.
My first impression of this product was how messy it was, as I opened the jar and nearly spilt the entire contents over my bathroom.
This whitening powder is very messy and has a finely milled, icing-sugar consistency that lathers into foam when applied to your teeth.
This makes the application tricky, but I soon discovered that wetting your toothbrush and then dunking it into the jar is your best bet.
MySweetSmile Dentist-Approved Teeth Whitening Powder: £24.99 (was £29.99)
I expected the formula to have a gritty texture and bitter taste, but it’s very pleasant and has a near-identical consistency to a foamy toothpaste.
The whitening powder is designed to work alongside your typical toothpaste, so I first brushed my teeth with trusty AquaFresh, then followed up with MySweetSmile twice a week, as advised.
After the first use, my teeth felt possibly the cleanest they’ve ever been and looked slightly brighter.
However, there was no evidence of whitening or diminishing stains.
MySweetSmile’s formula incorporates three key, enamel-safe ingredients that are clinically proven to protect enamel, fade stains, and remove plaque.
What I really loved about this product is how little you need to use it
What I really loved about this product is how little you need to use it.
Despite working in beauty, I’m actually very low maintenance (AKA lazy) and find sticking to lengthy routines rather tricky.
However, I stuck to my MySweetSmile routine and was even able to take the handy jar away on holiday with me, as you can pop it into hand luggage.
I used the powder twice a week for two weeks before I started noticing results.
Although my teeth weren’t white enough for the world to notice, I definitely saw an improvement in yellow stains and overall radiance.

MySweetSmile Teeth Whitening Strips review
MySweetSmile Dentist-Approved Teeth Whitening Strips: £9.99 (was £29.99)
Pros
- Pleasant taste
- Easy to use
- Visible results in a couple of weeks
- Easy to add into a beauty routine
Cons
- Have to have water handy to rinse
Rating: 9/10
I’ve always been sceptical about at‑home teeth whitening, especially with my coffee‑stained teeth.
However, after consistently using these strips for two weeks, I was thoroughly impressed.
There are 21 individual packs in each box, offering a three‑week treatment for just £9.99.
Every morning I applied the top strip to my upper teeth and the bottom strip to my lower teeth; each one covered roughly eight teeth (those visible when smiling).
After just two weeks, I was getting compliments on my teeth, with people saying how clear and bright they looked.
I especially noticed the strips had removed slight discolouration between the wonky teeth on my lower set, where I always struggle to properly get clean.
I would thoroughly recommend the strips as an easy, fuss‑free way to brighten your teeth quickly and affordably.

Although I’ve never been keen on investing in teeth whitening, I’ve always been drawn to whitening pens.
Whether it’s the click-click noise they make or the fact that they make teeth whitening on the bus possible, they’ve always seemed quite handy.
So, I’m delighted to confirm that MySweetSmile’s teeth whitening pen UK is, in fact, very transportable – I can’t say I’ve had the confidence to use it on the bus.
The pen dispenses a teeth-whitening gel onto the paintbrush applicator, which can then be applied to your teeth.
This offers a good level of precision, making quick work of tackling stains and areas of discolouration.
Just like the whitening powder, it has a pleasant, minty taste and doesn’t taste overly harsh or chemical.
I found the pen very easy to use — apply the teeth-whitening gel, wait 10 minutes, and then rinse away.
I’ll give you one piece of advice, though… Avoid applying the teeth whitening gel around other people, as you’ll need to leave it on for 10 minutes, which isn’t a good look.
MySweetSmile Precision Teeth Whitening Pen £19.99 (was £24.99)
Other than that hitch, it doesn’t leave a film or uncomfortable coating over the teeth and, unlike other whitening pens I’ve tried, is non-sticky and lightweight, meaning I barely noticed it once applied.
You can use the whitening pen up to three times a week, at any time of day.
I found myself using it a couple of times a week after drinking a particularly strong coffee or a glass of wine.
The whitening pen is enamel-safe and suitable for anyone with sensitive teeth, powered by PAP, a safer, less invasive alternative to hydrogen peroxide.
Whilst some shoppers have raved about experiencing instant results, it took me a little while before I noticed the real difference
Although some shoppers have reported instant results, I didn’t notice a significant difference until later.
However, after my first application, I noticed that my teeth looked whiter and brighter overall.
With continued use, the stains near the gaps in my teeth began to fade, which was an excellent result, and I’m looking forward to seeing how I progress.

MySweetSmile Enamel Care Serum review
MySweetSmile Enamel Care Serum: £24.99 (was £29.99)
Pros
- Gentle, pleasant application
- Promises instant results
Cons
Rating: 8/10
Tooth sensitivity is caused by compromised enamel and affects up to one in four of us.
Tooth decay, chipping and excessive brushing are all common culprits, and I’m definitely guilty of the latter.
So, I’m always looking for ways to strengthen and promote the health of my teeth.
I was intrigued to try this dentist-approved serum, thanks to its impressive ingredient list.
Whilst you can’t build new enamel, this serum uses nano-hydroxyapatite (nHA) to help remineralise it (a process of reintroducing necessary minerals to your teeth), which helps strengthen enamel and reduce sensitivity.
The formula also features theobromine, a natural alternative to fluoride, to promote tooth health and reduce decay.
That said, the teeth whitening serum still needs to be used alongside your typical toothpaste and can be used daily after brushing.
To use it, apply a couple of pumps to your toothbrush and brush for two minutes.
Sadly, this adds to your daily brushing time, which I think is counterintuitive because overbrushing is a common cause of sensitivity.
At first, this really put me off, as I always try to be careful with my gums by not overbrushing my teeth.
And that aside, adding extra time to your toothbrushing routine isn’t ideal if you’re in a hurry.
MySweetSmile Enamel Care Serum: £24.99 (was £29.99)
However, I found this serum very easy and gentle to use.
Put off by scary-sounding nano-hydroxyapatite, I initially assumed that this formula would be heavy and harsh.
But this wasn’t true in my experience. Instead, the serum lathers into a soft, fine foam and has a pleasant, subtle taste.
According to MySweetSmile, the serum can provide instant results alongside varying results with continued use.
I certainly didn’t experience results straight away, but I haven’t complained about my teeth over the past two weeks
I didn’t see immediate results, but I haven’t complained about my teeth since I started using it two weeks ago.
While I still can’t bite down on ice cream or slurp a steaming cuppa, with continued use, I have high hopes!

MySweetSmile review: The Verdict
If you’re after a gentler alternative to peroxide kits, MySweetSmile is worth a look
The clear winner overall was the Teeth Whitening Strips, which delivered on all fronts from realistic, affordable and fuss-free results.
The Teeth Whitening Powder delivers fast, visible results and is by far the most effective product in the range.
The Whitening Pen is ideal for quick top-ups or targeting specific areas, though the 30-minute dry time might put some people off.
The Enamel Care Serum is subtle but soothing, and while results take longer to notice, it’s a good option for those prone to sensitivity.
Overall, the range is well thought out, mess-free and genuinely works – especially if you’re consistent with it.
Is MySweetSmile approved by dentists?
The whitening powder is dentist-approved and works by lathering into a foam to provide speedy whitening.
The formula has three key ingredients that remove stains and plaque.
It’s much safer than professional whitening as it is free of hydrogen peroxide, which can damage enamel and increase tooth sensitivity.
MySweetSmile was launched by UK-based dental experts and has become the UK’s number-one teeth whitening brand on Amazon.
Thousands of glowing online reviews praise the hydrogen peroxide-free ingredients and the easy-to-use at-home products.
How often can you use MySweetSmile products?
MySweetSmile’s products are easy to incorporate into your existing brushing routine.
The MySweetSmile whitening pen is perfect for a quick touch-up on the go. You can also use it up to three times a week.
MySweetSmile Teeth Whitening Powder is one of the best teeth whitening powders on the market and can be used twice a week.
You can buy a jar with a six-month supply to get great bang for your buck.
If you need a quick fix when travelling, the brand’s teeth whitening strips are a great option.
You only need to use them for up to 30 minutes a day, and the strips offer whitening results after just one use.
