Oral-B iO Gentle Care Brush Head, Black, 2 Count, Compatible with Oral-B iO Electric Toothbrush Handles

The Oral-B iO Gentle Care brush head combines a unique round design with gentle micro-vibrations to deliver a comfortable yet effective clean, reducing plaque along the gumline. Smart Bristle technology fades in color to signal when it's time to replace the head, while dual-length, high-density bristles reach deep between teeth. Compatible with all Oral-B iO electric toothbrush handles, dentists recommend changing the brush head every 3 months.
