DrDent's teeth whitening strips have been given tens of thousands of glowing five-star ratings by Amazon customers,

The premium kit, which costs a budget-friendly price of £19.99, 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.
