The unique configuration cleans all three surfaces of the teeth at the same time. The soft outer bristles are angled to gently clean along the gum margin while the inner bristles clean and polish the tooth surface. The pulsating action has been clinical proven to deliver significantly enhanced plaque removal and is ideal for those who struggle to get a comprehensive clean with a manual toothbrush. Available in adult size only (12+). Use short gentle 'scrubbing' strokes ensuring thorough coverage of all teeth. Tilting the brush slightly gives optimal plaque removal along the gum line.
