Oral-B Pulsar Whitening toothbrush is battery operated to gently vibrate and polish away stains for a whiter, cleaner smile. Using the same technique to brush as a manual toothbrush, the bristles vibrate providing a gentle massaging and polishing action while brushing. The bristles penetrate between teeth where stain build-up often begins. Pulsar has soft vibrating bristles that help break up plaque between teeth. Plus, the split head design moderates the amount of pressure applied to your teeth and gums. Contouring to your unique smile, the Pulsar toothbrush will leave your smile bright and clean with every use. Color may vary. Age Group: adult.
