The Oral-B PRO Series 1 electric toothbrush helps clean according to the dentist's recommendations. The timed function encourages you to brush your teeth for 2 minutes and notifies you to change the cleaning area every 30 seconds. The round brush head removes up to 100% more plaque even in difficult areas compared to a conventional manual toothbrush, ensuring healthier gums. The built-in pressure sensor automatically reduces the cleaning speed if excessive pressure is applied.
