Brush heads for the sonic Black Whitening II - blue

Soft, high-tech bristles developed in Switzerland with activated carbon grains (ACP) neutralize plaque and whiten teeth without an abrasive effect on tooth enamel.

DIRECTIONS: Hold the brush on two teeth at a time for 5 seconds. Do not press. Do not make your own cleaning movements. Repeat with all teeth.

Replace the brush heads if they become worn, or replace them at least every 3 months.
