The iO 4 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.

Gum Guard alerts you to time spent brushing with too much pressure. Replace your Oral-B iO toothbrush head every 3 months for the best results.

Oral-B's only sensor signals if you brush too hard, too soft or just right for an effective and safe clean. Personalise your brushing choosing among 4 cleaning modes: Daily Clean, Sensitive, Super-Sensitive, Whitening. Maximise your clean with the iO lightring timer that celebrates a dentist recommended 2-minute brush and refill change alert.
