Amazon's 'dentist-approved' £19 teeth whitening solution hailed 'game-changer' for anyone wanting to erase 'a lifetime of tea and coffee stains'

Amazon customers are heaping praise on the site's best-selling teeth-whitening solution, which has been hailed a 'game changer' for those looking to erase a 'lifetime of stains' caused by tea, coffee and smoking. The £18.99 teeth whitening solution, which has been formulated by dental professionals, contains no peroxide, meaning it it safer to use than many other alternatives on the market.

DrDent strips normally cost £19.99 for a pack of 40 strips on Amazon- which equates to 20 sessions. However, for a limited time, Amazon is giving Prime customers an extra 5% off, bringing the price down to an even more budget-friendly price of £18.99.

Each premium kit contains a mouth opener, 40 strips, instructions and a shade guide to work from. It claims to make teeth eight times brighter with it working on stains from coffee, wine, soft drinks, food and smoking.
