Oral-B iO Replacement Brush Heads 5-Count — 4 Ultimate Clean + 1 Gum & Sensitive, Color-Fade Wear Indicator

Oral-B iO Ultimate Clean Replacement Brush Heads are precision-engineered refill heads that deliver a dentist-inspired, gentle yet thorough clean and signal when it's time for replacement.

These replacement brush heads are designed specifically for Oral-B iO electric toothbrush handles and pair advanced bristle geometry with smart bristle wear indicators so you get consistent performance without guessing. The set includes four Ultimate Clean heads for overall plaque removal and one Gum & Sensitive head tailored for extra-soft comfort around tender gum lines. Built with extra-soft, high-density bristles and an Oral-B round-head design, they adapt to tooth contours while providing a reassuringly gentle touch.

How do these brush heads tell me when to replace them?

Smart bristles fade from vibrant blue to white to show when cleaning power is declining, helping you swap heads at the right time. This visual cue removes uncertainty so you maintain effective brushing between changes.

• Color-fade bristles indicate wear and when to replace
• Designed to reach optimal effectiveness for about three months of regular use
• Compatible with iO handles so the indicator is visible each brush

What makes the Ultimate Clean variant different from Gum & Sensitive?

The Ultimate Clean head focuses on broad plaque removal using densely packed, angled bristles, while the Gum & Sensitive head uses extra-soft filaments to minimize irritation. Use Ultimate Clean for everyday deep cleaning and the sensitive head when you need a gentler touch around gums.

• Ultimate Clean: dual-length, angled bristles for 360° contact
• Gum & Sensitive: high-density, extra-soft bristles for comfort
• Swap heads easily to match your oral comfort or cleaning needs

Will these heads fit my Oral-B iO electric toothbrush?

Yes — these brush heads are made exclusively for Oral-B iO handles and are guaranteed to fit securely. The precision-fit connector ensures stable performance and efficient energy transfer from the handle to the head.

• Engineered for a snug, wobble-free attachment to iO handles
• Maintains intended brushing motion and power delivery
• Easy to remove and replace when indicators show wear

How often should I change the brush head and what care is recommended?

Dental professionals generally recommend replacing a brush head about every three months or sooner if bristles fray. Rinse the brush head after each use and let it air-dry upright to keep it hygienic between uses.

• Replace roughly every 3 months or when bristles visibly wear
• Rinse thoroughly and store upright to dry between uses
• Not intended for children under 3 years of age

Who is this for: This five-pack is ideal for iO toothbrush owners who want to maintain peak cleaning performance with a mix of deep-cleaning and gentle gum-friendly heads. It suits singles, couples, or families who prefer to swap brush heads for comfort or to stage replacements, and for anyone who appreciates a clear visual reminder to replace brush heads regularly.
