Made to remove years of stains while you sleep, this enamel-safe, teeth whitening pen features a precision brush that dispenses a hydrogen peroxide-based whitening gel directly on the surface of each tooth with just the click of a pen.
Each pen has 30 nightly uses so you can touch up when you need to and is designed for no tooth sensitivity during and after the whitening process.
