With the New Year here, many are looking for quick, affordable ways to refresh their look and start 2026 with confidence. Teeth whitening is often top of the list, and one £30 set of MySweetSmile Whitening Strips is now reduced to £17.99 – working out to 86p per day. 

The brand is also running multi-buy offers for anyone wanting to stock up or grab gifts for friends, with deals such as buy two, get one free, making each set even cheaper. The MySweetSmile Teeth Whitening Strips are designed for home use in 30 minutes. This makes them a convenient choice for anyone looking to brighten their smile while preparing for an evening out.

The whitening strips utlise Advanced PAP Technology to help eliminate yellowing and stains caused by coffee, tea, wine, and ageing. Each pack includes 21 treatments, sufficient for three seven-day cycles, and they are ‘enamel safe’ and ‘sensitivity free’.

To use, simply peel the strips and place them on the top and bottom teeth, leave them on for 30 minutes, then remove and rinse to reveal a brighter smile. Sometimes a tooth can look darker than the rest, especially if it’s crooked, crowded, or in a hard-to-reach spot, reports the Mirror. 

To help target tricky areas, MySweetSmile’s Precision Whitening Pen can help with those hard-to-reach areas. Currently reduced to £14.99 from £24.99, the pen’s fine brush tip allows users to apply the whitening formula precisely where it’s needed, be it a single stubborn tooth or gaps between teeth. The brand claims it works without peroxide and doesn’t cause sensitivity, delivering precise results.

Next up is MySweetSmile’s Teeth Whitening Powder, now available for £17.99, down from £29.99. Each tub provides a six-month supply, making it a cost-effective choice at just 48p per use, according to the website. 

The powder is dentist-approved and clinically tested, with a formula that’s ‘enamel safe and gentle on sensitive teeth’. For those who have to steer clear of ice cream or hot drinks due to sensitivity, MySweetSmile’s Enamel Care Serum could be a solution at £17.99, down from £29.99.

Unlike standard sensitivity toothpaste, this serum tackles the root cause by repairing and strengthening enamel, according to the brand. Infused with Hydroxyapatite (nHA), it aids in remineralising weakened enamel, protecting against decay, and naturally enhancing the brightness of teeth, as stated on the site.

Finally, there’s MySweetSmile’s Hyaluronic Gum Serum for £17.99, reduced from £29.99, which utilises high concentration Hyaluronic Acid (HA+) to hydrate and soothe gums, strengthen gum tissue, and help prevent future problems. For alternative options, shoppers might consider the Rapid White 5 Minute Dissolving Tooth Whitening Strips for £25 from Boots.

These are described as ‘specifically formulated to provide powerful teeth whitening’, and are ultra-thin and flexible for easy application.

Another choice is the Advanced Teeth Whitening and Cleaning Strips (14 Treatments) for £17.99, marked down from £39.99, at Smile Therapy. These boast an impressive 4.85 out of five star rating, and are formulated to ‘target surface-level stains’. 

The MySweetSmile products, meanwhile, have received strong ratings on Amazon. Regarding the Teeth Whitening Strips, one customer commented: “My teeth have aged over the years, but with this product they are as white as my crown of 30 years ago… they’ll never be sparkly white, but I’m happy with the improvement.

“Easy to apply without the torturous mouth piece, 30 minutes soon passes. Try not to move your lips too much, as minty gunk leaks. Very strong, sticky… a challenge to peel off, and important to brush your teeth straight after to remove gunky stickiness. Leave your teeth so clean and smooth. Trying their tooth powder now.”

Another user noted: “Can definitely tell the difference after a couple of weeks’ use.”

However, some had minor reservations, with one person sharing: “After using it for a few weeks, it seems to help remove stains from teeth. Easy to use but I need to keep it for at least 25 mins which is quite long. Also, after removing it, there is a very sticky residue left on teeth when it needs a bit of effort to remove it. Doesn’t taste bad either.”

Another customer shared their initial impressions: “Really clear instructions and comfortable to use. Didn’t really have high expectations and have only had for two days but I’m sure I am already seeing a difference!”

The majority of users were pleased with the results, as one satisfied customer exclaimed: “I’m impressed! I only used it twice and there is a noticeable difference already. I left it on for an hour instead of half an hour and wow! ! So now I will be ordering the powder and the pen! This product works!”
