Oral-B iO Series 5 review

The iO Series 5 is the point where Oral-B adds its app without the display and extra modes of the top iO models. Oral-B says the app tracks how and where you brush in real time, and the iO pressure sensor signals whether you are brushing too hard, too soft or just right, which is more feedback than the Pro 1000 offers. You get 5 Smart Brushing Modes, from Daily Clean to Super Sensitive and Whitening, a built-in 2-minute timer and a Brush Head Tracker that reminds you when to replace the head. Oral-B claims 100% more plaque removal and 2.5x as much between teeth vs a manual brush, with healthier gums in 1 week. The box includes a hard travel case. The regular price is $119.99, with $99.99 on sale in November 2026, and Oral-B offers a 2-year warranty and a 30-day money-back guarantee. Replacement iO heads cost more than standard Oral-B heads, so check refill prices before committing.
