The iWhite Dark Stains toothbrush has soft dental bristles which are loaded with the Dark Pigment Adsorption Technology. This technology is based on the presence of specially selected charcoal particles. These particles are known for their natural whitening and strong adsorbing qualities, and hereby help our teeth to stay cleaner and whiter. Unlike ordinary toothbrushes that simply scrape your teeth to remove plaque, iWhite Dark Stains toothbrush has extra features to fight stains from coffee, tea, tobacco and wine. The unique structure of charcoal gives it the ability to adsorb staining particles, to eliminate odour causing compounds and to regulate the humidity of the surface of the filament which prevents harmful bacteria from growing within the brush itself. The toothbrush is designed with an ergonomic handle, improving accuracy and comfort during brushing, and with a small head to reach interdental areas easily.
