Oral-B iO Gentle Care Toothbrush Heads, Black - 8 Pack (2 Packs of 4)

The Oral-B iO Gentle Care Replacement Brush Heads in black come in a convenient 4-pack, designed exclusively for the Oral-B iO range of electric toothbrushes for a guaranteed perfect fit every time. Each head is densely packed with thousands of soft bristles that provide a thorough yet gentle clean — making them a particularly good choice for anyone with sensitive gums or those who simply prefer a lighter touch.

A practical colour-changing indicator makes it easy to know when it's time for a replacement. The bristles gradually fade from their original colour to white over time, giving you a clear visual cue to swap the head and maintain the best possible clean. Dentists generally recommend replacing brush heads every three months, as worn bristles become less effective at removing plaque and debris from the tooth surface.

This black colourway is a smart option for households with multiple iO users, making it easy to tell heads apart at a glance. Oral-B iO brush heads are engineered to work solely with the iO handle system, so you can be confident you're getting the performance the toothbrush was designed to deliver.
