home. In 2025, these smart brushes dominate the market thanks to a magnetic
drive system that delivers dentist-approved results with precision and comfort.
But which iO model actually
fits your oral-health goals? This Oral-B iO buying guide dives
into everything: how each iO series compares, which model offers the best

feedback, and smart timers that protect your gums.
Whether you’re seeking the best budget brush or the best Oral-B electric upgrade, by the end of this post you’ll know exactly which Oral-B iO toothbrush to buy for your smile.
The
Oral-B iO Range Explained
Oral-B’s iO Series 2 through 10
represent the brand’s most advanced generation yet. Each brush in the iO
line uses the same magnetic technology to power its round brush
head, but the smart features, displays, and app connectivity evolve
dramatically from one model to the next.
- iO Series 2 & 3:
streamlined, affordable introductions to the iO range—great for
everyday cleaning and travel.
- iO Series 5 & 6:
mid-range smart models balancing cost and customization.
- iO Series 7 & 8:
premium choices offering richer feedback via the Oral-B app.
- iO Series 9 & 10:
ultimate luxury with AI tracking and on-charger guidance (iO
Sense Smart Charger).
Dentists consistently recommend the Oral-B
electric toothbrush family because the micro-vibrating bristles and 2-minute
timer help users brush effectively without damaging enamel or gum tissue.
Dentist Tip: Oral-B’s iO magnetic drive keeps bristle motion
smooth, reducing the chance you’ll brush too hard one of the leading
causes of gum recession.
