“MySweetSmile claims its teeth whitening powder helps remove built-up stains, yellowing and plaque caused from food, drink and even smoking,” began our tester. “Dentist-approved (100 per cent fluoride and peroxide-free, as well as being non-abrasive), the powder combines pentasodium triphosphate and calcium carbonate in order to remove plaque and keep teeth squeaky clean and pearly white.”

“At first, we thought the powder might be messy to use but it wasn’t at all. It involved a quick process of dipping our toothbrush into the powder before brushing for four minutes. Compared to most products which recommend you use the whitening products nightly, the time frame for this one is twice a week, which was easy to fit into our routine alongside our regular brushing,” our reviewer added.

Most importantly, their final verdict was that “it gave us a naturally upgraded white smile from just a couple of weeks’ use.” So, if you’re tempted to try, now may be the time, with a current saving of 20 per cent.
