Oral-B Pro-Expert CrossAction All in One toothbrush uses advanced technology to protect teeth, promote healthy gums and provide fresh breath. It removes more plaque than a regular manual toothbrush. CrissCross bristles adapt themselves to the shape of the mouth to effectively remove plaque for a superior level of clean, while remaining gentle on teeth and gums. Unlike ordinary toothbrushes with straight bristles, Pro-Expert All in One toothbrushes have CrissCross bristles angled to flex into hard-to-clean areas, sweeping away up to 99% of plaque. Positioned in opposing directions, CrissCross bristles are designed to flex and then straighten, actively penetrating between the teeth and along the gum line to lift and sweep plaque away.
