SmilePro’s Advanced Teeth Whitening Kit is now available for £44 in a flash sale, down from £87 — a 50% discount. The kit promises dentist-level results at home, with each treatment costing as little as £2. It uses dual-action LED technology, combining blue light to accelerate the whitening formula and lift deep stains from coffee, wine, fizzy drinks and smoking, with red light to support gum health and reduce inflammation. The enamel-safe gel can whiten teeth by up to eight shades, according to the company.
The application process is straightforward: users apply the gel with a pen-like applicator, insert the mouth tray, and activate the accelerator light for 10 to 30 minutes while going about daily activities. The kit comes with a 30-day satisfaction guarantee, allowing customers to request a refund if they are not satisfied with the results.
Customer reviews are largely positive, with one user noting: “Where has this been all my life? Amazing product! Noticed instant results on the first use!” Another said: “After just a couple of applications the difference was obvious with brighter, whiter teeth.” However, one reviewer mentioned a minor issue: “My only issue is the sensitive touch power button which turns on while I try to rinse the product.” Despite this, many reported no sensitivity problems, with one shopper stating: “I have had sensitive teeth in the past but haven't had any problems with this product.”
For comparison, the Polished London Professional Teeth Whitening Kit from Boots is priced at £49.99 and also uses LED dual-light technology, while Boots’ Rapid White 1 Week set costs £10.67 but has a lower customer rating of 2.7 stars. The SmilePro kit, backed by over half a million users and thousands of five-star reviews, offers a competitive alternative for those seeking brighter teeth without a trip to the dentist.
