A tea drinker has reported that their yellow teeth looked “much whiter” after the first use of MySweetSmile whitening strips, which are currently available for around 32p per strip as part of a Buy 2 Get 1 Free promotion.
The customer, who said their two front teeth were “literally yellow due to smoking and drinking tea all day,” noted that from the first time of use, their teeth appeared visibly whiter. The feedback comes as the brand’s Teeth Whitening Strips are priced at £19.99, down from £39.99, with the deal allowing shoppers to pick up three boxes—63 treatments (126 strips)—for £39.98.
How the whitening strips work
The strips use PAP as the key active ingredient, which works beneath the enamel surface to tackle deep-set yellowing that ordinary toothpaste and surface polishes cannot reach. The peroxide-free formula is designed to be gentle on gums and suitable for those with sensitive teeth.
Users apply one strip to the upper teeth and one to the lower, leave them for 30 minutes, then peel off and rinse. The brand also offers a Teeth Whitening Powder, available in fresh mint and strawberry, reduced from £29.99 to £17.99, with three jars costing £39.98 instead of £89.97. Each jar contains a six-month supply, meaning brighter teeth could cost as little as 44p per day.
Customer reviews and other offers
MySweetSmile has a 4.5 rating on Trustpilot from 8,712 reviews. One customer said: “Absolutely amazing just ordered another three. Tried every tooth whitener on the market, but this stuff is the best.” Another wrote: “It really worked! Even after the first use I noticed my teeth were whiter! Thank you for a product that does what it says it will do! Delivery was quick also.”
Some customers noted delivery delays, with one saying: “Arrived a little bit later than I was expecting.” However, a five-star reviewer shared: “It has only been 7 days since I received my order and started using it. I can already see that my teeth are a shade lighter.” Another buyer added: “After trying MySweetSmile’s whitening powder - I knew i had to try the new PAP Whitening Strips to pair with it. It’s safe to say I'm nothing short of amazed.”
The brand also offers a Gum Serum, discounted by 40%, with three bottles priced at £35.98—effectively £11.99 apiece. Enriched with hyaluronic acid, panthenol and xylitol, the serum aims to soothe tenderness and irritation, with the brand claiming that within thirty days, gums should bleed less frequently. Adding all three items to a basket would save shoppers £61.99, securing the trio for £37.98 instead of £99.97.
