The Oral-B PRO Series 1 electric toothbrush helps you brush the way your dentist recommends. The timer helps you brush your teeth for 2 minutes and notifies you every 30 seconds to change the brushing area. The round brush head removes up to 100% more plaque than a conventional manual toothbrush, even in hard-to-reach places, for healthier gums. The integrated pressure sensor automatically reduces the brushing speed if you apply too much pressure.
