Most people think they are brushing effectively, but brushing well is harder than it seems. Plaque often remains in the places that are hardest to clean, including along the gumline, between teeth and around molars. In fact, 80% of people miss at least one area when brushing, and 60% miss their molars. Over time, that plaque buildup can impact oral health and well-being.

Oral-B iO’s superiority starts with its oscillating-rotating technology, paired with Oral-B’s unique dentist-inspired round brush head, to make a superior clean easier to achieve. The round head surrounds and adapts to each tooth, helping remove plaque where it builds most. Synchronized rotations, micro-vibrations and smart pressure guidance help people brush more completely, clean thoroughly yet gently, avoid brushing too hard, and reach difficult-to-clean areas with less effort.

Better brushing habits and healthier gums do more than improve everyday oral health. They can also help reduce the need for more intensive treatment over time. Oral health is connected to overall wellbeing, and prevention at home can help reduce future treatment needs, discomfort and cost over time. A P&G and American Academy of Family Physicians survey found that many people care about oral health, but very few spontaneously connect oral health with whole-body health, highlighting an opportunity to make daily oral care feel more like an act of prevention.
