Oral-B 3D White Advanced Seal Whitestrips are thin, flexible whitening strips which conform to the shape of teeth, containing the same enamel-safe whitening ingredient used by dentists. The new Advanced Seal Anti-Slip Technology makes for even easier application. Oral-B 3D White Whitestrips help removes up to 10 years of stains for up to 12 months of a naturally radiant white smile. Oral B 3D White White strips Luxe with Advanced Seal Technology’s no slip grip means the strip stays put so you can talk and drink water while whitening teeth, whilst the strip moulds to the shape of your teeth and comes off cleanly. Use once a day for 60 minutes, you should start seeing results in just one week. This product uses the same enamel-safe teeth whitening ingredients dentists use for a comfortable, no-hassle at home teeth whitening experience. Similar to other White strips, the Oral B 3D White White strips Luxe Advanced Seal product contains thin, flexible strips that are coated with a tooth whitening gel containing peroxide. Designed to conform to the shape of your teeth, they work by keeping the whitening gel in place against your teeth to get at stain build-up on and below the surface of tooth enamel. However, the high performance polymers in Oral B 3D White White strips Advanced Seal enable an easier application, a stronger grip and cleaner removal.
