MySweetSmile's Dentist-Approved Teeth Whitening Powder has been reformulated with a new 3-in-1 blend that the brand says can deliver visibly whiter teeth in as little as 14 days. The powder is currently on sale from £29.99 to £24.99 and lasts up to six months, working out at approximately 32p per application. Designed to be gentle yet effective, the enamel-safe formula is suitable for sensitive teeth and helps lift stains caused by coffee, tea, red wine, smoking, and ageing.
Shoppers Report Quick Results and Confidence Boost
Users have praised the product for its easy application, which involves dipping a damp toothbrush into the powder, adding toothpaste, and brushing for two minutes. One customer wrote: "I asked my brother why his teeth looked so great!! He directed me to MySweetSmile! Ordered Friday and arrived Saturday! Already so impressed! I used the powder Saturday and Sunday and can already see the difference! I'm a smoker, coffee and red wine drinker so my teeth are really under pressure! Honestly I can feel my confidence sneaking back! It's blown my mind how quick it works!"
Another customer noted: "After years of smoking my teeth have been badly stained. Since regular use of this product my dentist has stopped his regular six month 'staining plus, plus, plus' assessments! I couldn't ask for more." A 60-year-old smoker and tea drinker added: "I purchased this system after checking out the reviews. This product does what it says. Gradual whitening with little sensitivity. I like how my teeth appear and the price is right. The powder pot is huge and will last up to 6 months!"
Dentist-Approved with High Ratings
The powder holds an impressive 4.5-star rating. One user shared: "Stains never appear since using this. My teeth are definitely whiter. My confidence in smiling has improved. Even my dentist was impressed." Another reviewer titled their feedback 'Wow, wow and wow again', stating: "Definitely 100% does what it says on the box. This is only my 4th night wearing the strips and I've noticed a big difference already. I've been using the powder for about 3 weeks now and I've gone down 5 shades already."
Delivery Issues Noted by Some Customers
While most feedback is positive, one customer flagged a delivery problem, deducting two stars from their rating. They said: "I am only giving 3 stars because of the delivery service. I received an email to say my parcel had been delivered on 30/05/2026. I actually only received it today as it had been left at the wrong address and outside. I absolutely love the products and have ordered numerous times but the delivery has let MySweetSmile down on this occasion."
