1/5Oral-B iO Series 9 Electric Toothbrush
The Oral-B iO Series 9 is the most technologically advanced electric toothbrush we tested, combining a magnetic drive system with micro-vibrations that deliver a dentist-level clean in just two minutes. The interactive color display tracks your brushing zones in real time and displays a smiley face when you have covered every quadrant thoroughly, which in our testing genuinely improved brushing consistency over a two-week period. Seven cleaning modes ranging from Intense Clean to Super Sensitive mean this single brush handles everything from deep stain removal to post-surgery gentle care. If budget is not a concern and you want the absolute best clean available at home, this is the toothbrush to buy.
