The Mr.White battery-powered toothbrush with pulsar technology, i.e. vibration technology, offers more effective oral hygiene than a conventional toothbrush. The brush head is specially designed to reach all tooth surfaces in the child’s mouth. It has soft, rounded bristles to be as gentle as possible on tooth enamel and gums. The handle is shaped and sized so that the child can comfortably manipulate it and the adult can hold it to teach their child the correct way to brush their teeth. This toothbrush is the ideal transition between a manual toothbrush and an electric toothbrush with rotary motion, recommended for children 4+ years. It is recommended to change the toothbrush head every 3 months or when the bristles appear visibly deteriorated. The toothbrush comes with 1 replaceable 1.5V AA battery.
