Philips HX6510/22 is a rechargeable sonic toothbrush with one mode and three brush heads. It features a two-minute timer to ensure the recommended brushing time, and a Quadpacer interval timer to encourage thorough brushing of each quadrant of the mouth. The Sonicare dynamic cleaning action drives fluid between teeth, and the angled brush head neck allows for better reach to back teeth. It removes up to 2x more plaque than a manual toothbrush and is clinically proven safe and gentle. The toothbrush also helps whiten teeth by removing tea, coffee, and other stains.
