The Oral-B Pro Series 3 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 and ensures healthier gums. The 360° pressure control lights up red and reduces the brushing speed if you brush too hard.
