The iO 5 electric toothbrush features Oral-B's best technology combining a dentist-inspired round brush head with micro-vibrating bristles for a professional purifying clean feel at home. The Smart Pressure Sensor helps prevent you from brushing either too hard or too softly to better protect your gums. A.I. Brushing Recognition recognizes your brushing style and guides you to better brushing every day. Connects to the free Oral-B App for real-time brush tracking & guidance across 6 brushing zones. Replace your Oral-B iO toothbrush head every 3 months for the best results. It removes 100% more plaque and up to 160% more between teeth than a manual brush. The A.I. powered Oral-B App tracks how and where you brush in real-time, and the iO Pressure Sensor signals if you brush too hard, too soft, or just right. Personalize your brushing with 5 cleaning modes: Daily Clean, Intense Clean, Sensitive, Super-Sensitive, and Whitening. The iO Lightring Timer features a dentist-recommended 2-minute brush and a refill change alert. This item includes a UK 2-pin charger; adapter not included.
