Spinbrush PRO CLEAN Replacement Brush Heads Soft feature Dual-Action Technology — a combination of spinning and side-to-side brushing heads — for the ultimate in cleaning. They remove up to 70% more plaque in hard-to-reach places than a manual brush* with micro-cleaning bristles. The green colour-wear bristles fade when it's time to change the head. Power up today for a cleaner, fresher and more radiant smile than ever before with Spinbrush.
