For healthier gums in just one week, with the most advanced Oral-B technology, remove 100% more plaque and up to 160% between teeth compared to a manual toothbrush. The round brush head with micro-vibrating bristles is inspired by dentists for a professional cleaning feel at home. The smart pressure sensor ensures you brush neither too hard nor too gently, better protecting your gums. The A.I. connects to the free Oral-B app for real-time brushing guidance across six cleaning zones. Replace the Oral-B IO head every three months for optimal results. Don't miss any spots with the A.I.-controlled Oral-B app, which tracks how and where you brush your gums using the Oral-B IO pressure sensor. By selecting from five cleaning modes: daily clean, intense clean, sensitive teeth, super sensitive teeth, and whitening, you maximize your cleaning with the IO light ring timer. This corresponds to the two-minute brushing time recommended by dentists and alerts you when it's time to change the brush head. The round brush heads from Oral-B reach areas that rectangular manual toothbrushes cannot. Experience superior cleaning with the number one brand most commonly used by dentists worldwide, and enjoy the long-lasting use of the lithium-ion battery. We offer a 30-day money-back guarantee.
