The Oral-B iO3 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, protecting your gums and alerting you to excessive pressure. Replace your Oral-B iO toothbrush head every 3 months for optimal results. This toothbrush removes 100% more plaque than a manual brush. Protect your gums with the iO Pressure Sensor, which signals if you are applying the perfect pressure for an effective and safe clean. Maximize your clean with the iO Lightring Timer, which celebrates a dentist-recommended 2-minute brush and provides a refill change alert. Personalize your brushing by choosing among 3 cleaning modes: Daily Clean, Sensitive, and Whitening. Oral-B round brush heads reach where rectangular manual brushes don't, providing our best clean. As the #1 brand most used by dentists worldwide, Oral-B offers a long-lasting charge with its Lithium-ion battery. Switch to Oral-B electric toothbrushes carefree with a 30-day money-back guarantee (T&Cs and redemption at Oral-B website). This thoughtful gift idea features advanced technology and exceptional oral care.
