iO Gentle Care Brush Heads — 6 Count

These replacement heads are made exclusively for Oral-B iO electric toothbrush handles. The pack contains six black brush heads with soft nylon bristles designed for gentle daily cleaning. They suit adults who want a precise fit and a softer brushing experience on sensitive gums.

Thermals Noise Power

No thermal output, noise or electrical draw is produced by the brush heads themselves. Power consumption and sound levels depend entirely on the iO handle they attach to. The heads add no measurable weight or heat during normal use.

Smart Bristle Indicator

Each head features blue bristles that fade to white when cleaning performance drops, removing guesswork about replacement timing. The colour change signals when to swap the head so brushing efficacy stays consistent. Dentists advise changing every three months for best results.

Questions about this item

How do I fit the Oral-B iO Gentle Care head onto my iO handle, and what step do people miss?

Align the head with the metal drive shaft and press straight down until it clicks; the common mistake is twisting instead of pushing, which leaves the head loose and reduces the 100% plaque-removal benefit.

When do the 4000+ soft bristles need replacing, and how does the head tell me?

Smart Bristles fade from blue to white when cleaning power drops; dentists recommend a new head every three months or sooner if wear appears.

What limits cleaning performance first during long brushing sessions with these heads?

The ultra-thin adaptable bristles are designed for gentle gliding, so sustained pressure causes them to flex rather than scrub, reducing plaque removal before the motor or battery becomes a factor.
