Philips Sonicare ProResults X2 Electric Toothbrush Refills

Designed to optimize performance: rounded head profile cleans hard-to-reach areas.
Removes up to twice as much plaque: This head removes up to 2 times more plaque than a manual brush.
Optimized sonic movement: Our technology drives bubbles between teeth and along the gum line to break up plaque, and brush movements sweep away.
Brush heads wear out, change them every 3 months for optimal performance.
