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