Oral-B iO Gum & Sensitive Replacement Brush Heads — Black 6-Count, Extra-Soft SmartBristles

If you use an Oral-B iO handle and prefer a softer touch for sensitive teeth and gums, these replacement heads combine a high-density, dentist-inspired bristle design with iO smart bristle fade technology. Each head adapts to tooth contours to lift plaque while minimizing abrasion, and a visible color-change feature helps you know when the brush head’s effectiveness is declining.

How do these brush heads protect sensitive gums without sacrificing cleaning?

The iO Gum & Sensitive heads use over 4,000 extra-soft bristles arranged in a curved pattern that follows the shape of teeth and gumlines. That combination helps remove plaque from contact surfaces while reducing pressure points on delicate tissue.

• 4,000+ ultra-soft bristles for gentler contact
• Curved bristle layout to reach along gum margins
• Round Oral-B brush head design for thorough, localized cleaning

What makes the iO replacement heads smart or different from standard brush heads?

These refills include Smart Bristles that fade from blue to white as bristle effectiveness decreases, providing a clear, visual reminder to replace the head. The precision fit and iO-compatible design also ensure consistent performance with Oral-B iO handles.

• Color-fade bristles indicate replacement timing
• Exact-fit connection for Oral-B iO handles
• Engineered bristle density for balanced cleaning power

How often should I swap to a new brush head and why?

Dentists commonly recommend changing a brush head about every three months or sooner if bristles show wear. Replacing the head on that schedule helps maintain effective plaque removal and ensures the Smart Bristles’ fade signal stays meaningful.

• Replace every ~3 months or when bristles fray
• Smart Bristles visually fade to white as an indicator
• Fresh heads preserve intended cleaning performance

Are these brush heads compatible with all Oral-B handles and safe for young users?

These replacement heads are designed specifically for Oral-B iO electric toothbrush handles and deliver the best fit and performance with that system. They are not intended for children under age 3; consult product guidance for younger users.

• Compatible with Oral-B iO series handles
• Not for children under 3 years old
• Sold in a 6-count pack for ongoing replacements

Who is this for: Ideal for adults who use an Oral-B iO electric toothbrush and want a softer, gum-friendly brush head that still aims to remove plaque effectively. It’s well suited to people with sensitive teeth or gums who prefer a visual replacement cue and want to stock up with a six-pack for regular rotation.
