The Oral-B water flosser uses micro-air bubble technology to prevent the formation of bacterial plaque. Oral-B water flossers are a great addition to your daily brushing routine and the perfect choice for improving your gum health. The Oral-B water flosser gently removes food particles, gently massages the gums, and provides a fresh and clean feeling in your mouth. 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 compared to a regular manual toothbrush, promoting healthier gums. The built-in pressure sensor automatically reduces the brushing speed when you apply too much pressure.
