UPSHELL Easy Smile Professional Teeth Whitening Kit with 32X LED Lamp 3 Gels Fast and Effective Whitening, Removes Deep Stains Safe for Tooth Enamel

SIXTEEN MINUTES, SIXTEEN BLUE LEDS: load the tray, press once and the lamp runs a full 16 minute cycle across both arches, then switches itself off. A complete at home teeth whitening kit with nothing to plug in and nothing to time yourself. WHAT IT ACTUALLY DOES: it lifts surface stains left by coffee, tea, red wine and smoking. It works over a two week course, not in one sitting, and it does not change the natural underlying shade of your teeth. Better you know that before you buy. NOT FOR VENEERS, CROWNS OR IMPLANTS: whitening acts on natural enamel only, so caps, bonding and dentures keep the colour they were made in. Reviewers with sensitive teeth call the sessions gentle, but rest a few days if yours start to twinge. CHARGING AND USE: the lamp flashes while it charges and buzzes once when it is full, that is normal and not a fault. Brush first, dry the teeth, apply a thin line of gel, sit for 16 minutes, then rinse. Three sessions a week for a fortnight. IN THE BOX: the 16 LED lamp, charging cable, three whitening gel pens, mouth tray and shade guide. Gel refill pens are sold separately, so the lamp keeps working long after the first pens run out.
