The Philips Sonicare 2100 Electric Toothbrush removes up to three times more plaque than a manual toothbrush without being overly harsh on your teeth or gums. Includes a two minute timer so you can optimise your brushing time, and the powerful bristles provide 31,000 brush strokes per minute for a deep, thorough clean. Comes with a rechargeable lithium battery which lasts for 14 days and is charged via a handy USB charger.
