The Oral-B Pulsar Gum Care is a battery operated toothbrush with vibrating bristles to gently massage and stimulate your gums, and remove plaque. Using the same technique to brush as a manual toothbrush, the micro-pulse bristles pivot and pulse to penetrate deep between teeth. Pulsar is shown to reduce gingivitis and improve gum health, while promoting healthier, firmer gums. Just as easy to use as a regular manual toothbrush. Oral-B, the brand more dentists use themselves worldwide.
