Philips HX3631/06 is a sonic toothbrush that helps you achieve a superior clean. With its advanced sonic technology, it delivers up to 15,000 brush strokes per minute, removing more plaque than a manual toothbrush. The HX3631/06 also features a smart timer that helps you brush for the dentist-recommended two minutes, and a pressure sensor that alerts you if you're brushing too hard. The toothbrush comes with one PowerUp brush head, which is designed to whiten teeth and improve gum health. The HX3631/06 is also gentle on teeth and gums, and is safe to use on all dental work.
