Oral-B 3DWhite Whitestrips use the same enamel-safe whitening ingredient used by dentist. They are thin, flexible strips that are coated with a tooth-whitening gel containing peroxide. Once you unwrap them and place them across both upper and lower sets of teeth, they stay on until it's time to remove them. The recommended use is to keep on the surface of your teeth for 60 minutes once a day to remove stain build-up both on and below the tooth's surface#oralb #oral-b #electrictoothbrush #toothbrush #toothpaste #floss #mouthwash #teethwhitening #refills #whitening #clean #fresh #charger #travel #kids #crossaction #colour #gum #sensitive #enamel #white #black #rose #blue #pink #mint Advanced Seal Anti-Slip Technology: Strong grip and good fit Visibly Whitens teeth: Removes up to 10 years of stains in as little as 14 days Removes tough coffee, wine and smoking stains 3 Easy Steps : Peel, Apply & Reveal your whiter smile Recommended to be used with the 3DWhite Collection
