When it comes to teeth whitening, there are endless products and treatments available promising to deliver pearly whites and Hollywood smiles. However, Amazon shoppers have found a product that tackles ‘seep-set stains’ and brightens smiles for under £25, and say it’s ‘turned back the clock’ on their smile.

MySweetSmile is celebrating its fifth birthday this year, and to mark the occasion, has launched a sale on its website offering shoppers money off their teeth whitening powders, strips, pens and more. For those looking for a complete routine or to stock up on a favourite, there’s also a three for two offer running.

No codes are required as all discounts are automatically applied at checkout, and the offers are available site-wide. The on-site sale makes the products even cheaper than Amazon, where the brand’s tooth whitening powder is the number one best-seller in the teeth whitening category, having sold more than 7,000 times in the last month.

Within the range of products on offer, customers have a plethora of choices such as the Teeth Whitening Powder, now priced at £24.99, reduced from £29.99. This product is clinically proven and dentist-approved, designed to lift deep-set stains and prevent new ones from forming without using any harsh peroxides, causing sensitivity or damaging enamel, reports the Manchester Evening News.

The Teeth Whitening Strips are also discounted to £24.99 from £29.99. These easy-to-use, non-slip strips deliver quick results without harming the enamel. The Precision Teeth Whitening Pen will also be available with a £5 discount.

It's designed for targeted whitening for those desiring extra sparkly teeth. Its fine brush tip allows customers to apply the formula precisely where needed, and it doesn't use any peroxide, so there should be no sensitivity caused to the teeth.

For customers with damaged or sensitive enamel, the Enamel Care Serum could be an ideal choice. This product targets the root cause of sensitivity by repairing and strengthening the enamel.

For optimal results, customers simply follow their regular night-time brushing routine before applying the serum, dispense two to three pumps onto their toothbrush, brush for two minutes and spit out any excess.

Sensitive gums are a widespread concern, but now individuals can get their hands on the Gum Serum from MySweetSmile, infused with hyaluronic acid. This ingredient promises to hydrate, calm inflammation and fortify gum tissue when applied.

It's recommended to use this serum following one's usual toothbrushing routine, by dispensing two pumps onto the tongue and then gently spreading it across the gums before allowing it to absorb for a couple of minutes. Not every product will suit everyone's needs, and if this isn't the right fit, there are other options available.

Take, for instance, the Rapid White - Blue Light Tooth Whitening System priced at £23.33 from Boots, which is clinically proven to lighten teeth up to five shades in just two weeks and features sensitive action formulas that are peroxide-free. Another alternative is the Spotlight Whitening Teeth Whitening Pen, it costs £14.95 from Lookfantastic, which offers an easy-to-use pen that provides professional-looking results from the comfort of home and helps reduce stains for a more radiant smile.

Feedback from customers on the MySweetSmile website includes a glowing testimonial from Margaret, aged 63, who remarked about the Teeth Whitening Powder: "I always thought my yellow teeth were just part of ageing, but after just a few uses of MySweetSmile, I can't stop smiling at the mirror. My teeth feel so much cleaner and brighter - it's like I've turned back the clock on my smile".

Emily, 39, shared: "I was sceptical at first, but this really works. My teeth looked dull and yellow no matter how much I brushed, but now they're sparkling clean and bright. The compliments haven't stopped, and I feel so much more confident".

However, Amazon reviews presented a mixed bag of opinions. One customer noted: "I have only just started using this, so I have not seen much difference yet, but the powder leaves your mouth smelling fresh."

Another user expressed slight disappointment: "I bought this as it was recommended online. I'm not a smoker and I haven't been drinking much, I do drink coffee regularly but I equally regularly clean my teeth. There's an initial improvement but I'm not sure it's what I expected. I used it every day in the first week and only noticed the difference post brushing. Shortly after that - little difference."

Tom, 34, praised the Teeth Whitening Strips, saying: "I'm always running around with work and barely have time for self-care. These strips fit perfectly into my busy routine, and the results are incredible. My teeth are whiter, and I feel so much more confident."
