With a frequency generating up to 42,000 brush strokes per minute, the Sonic Generation 8 Winner is one of the most efficient toothbrushes on the market. Not only is mechanical cleaning enhanced, but the high frequency creates a phenomenon known as ‘non-contact cleaning’. This hydrodynamic action generates currents of fluids which clean interdentally and subgingivally. The UltraSoft Konex HD bristles are five times thinner than other UltraSoft bristles, providing comfort during brushing - particularly for those with sensitive teeth and gums. Their tapered shape allows them to penetrate the interdental spaces and gingival margin and their flexibility enables them to adapt to the contours of each tooth. Cleaning modes: Sensitive mode is gentle and efficient. It thoroughly cleans without irritating sensitive teeth and gums. Active deep mode is thorough and powerful. It effectively removes plaque for a deeper clean. Whitening mode cleans and brightens. It naturally whitens teeth by removing extrinsic stains from the teeth. Yoga mode smoothes and regulates. It promotes wellbeing and mindfulness while cleaning teeth. The Sonic Generation 8 Winner is especially recommended for sensitive teeth, periodontitis, implants, braces, bridges and other dental replacement solutions. Due to its high frequency, it is recommended for use with a compact foaming toothpaste. Users are advised to start with the Sensitive mode to acclimatise to the tickling sensations of the brush.
