The newly upgraded electric toothbrush, with the latest sonic technology, performs superior cleaning along the gum line, removing 125% of plaque, whitening teeth and improving oral health, better than manual toothbrushes in two weeks. Five high performance brushing modes - clean (mild), white (strong), polished (strong reversal frequency), gentle (mild reversal frequency) and sensitive (soft), are available to suit the different conditions of your gums, so you can choose different modes according to your preferences and the advice of your dentist. Built-in smart timer controls remind you to move to the next quadrant of your mouth at 30-second intervals for a total of 2 minutes (4 quadrants), which is highly recommended by professional dentists for proper brushing. IPX7 waterproof for bathtubs and showers. Don't worry about water getting into the charging port to shorten battery life, which is safer than USB chargers. Date First Available May 24, 2024
