Philips Sonicare DiamondClean Standard Black Brush Heads HX6066/31, 6 Pack;

With 44 percent more bristles than ProResults Standard, DiamondClean toothbrush heads remove more plaque deep between teeth and along the gum line to decrease your risk of gingivitis. The diamond shaped bristles of the brush head gently clean and whiten teeth by removing surface stains and buildup. The DiamondClean brush heads remove up to 5x more plaque than a manual toothbrush. Replace Every Three Months You can't see it, but your brush head wears over time. Blue reminder bristles fade in color to let you know when it's time to replace the brush head. Dental professionals recommend replacing your brush head every three months. Sonicare technology helps you remove up to two times more plaque compared to a manual toothbrush.
