Philips Sonicare ProtectiveClean is an electric toothbrush with advanced sound technology. The toothbrush contains a pressure sensor to protect teeth and gums from excessive pressure when brushing. It also has 2 brush settings: Clean for an excellent cleaning and white for an optimal removal of discolorations. In order to ensure effective cleaning, a reminder function signals when the brush head needs to be replaced. An integrated timer informs when a part of the mouth has been cleaned long enough and when the total time of 2 minutes has elapsed. This ensures that the recommended cleaning time is adhered to. The battery status is indicated by a small lamp, so that it is easy to read when the battery needs to be recharged.
