Replacing your electric toothbrush head every three months is one of the simplest things you can do for your oral health — but with several Oral-B head options available, it helps to know which one is right for your brush and your household. Our Electric Toothbrush Replacement Heads collection carries three of the most popular: the CrossAction for everyday adult use, the Pro Kids Spiderman for children, and the iO Ultimate Clean for Oral-B's premium iO system. Here's how they compare.
1. Oral-B CrossAction Replacement Heads with CleanMaximiser – 5 Pack
£42.00
The CrossAction 5-Pack is the go-to everyday head for adult Oral-B users. The bristles are angled at 16 degrees and engineered to reach deep into interdental spaces, removing up to 100% more plaque than a standard manual toothbrush. The standout feature is CleanMaximiser technology — the bristles gradually change from green to yellow, giving you a clear visual cue when it's time to replace the head. No guesswork, no forgetting. Five heads per pack means you're covered for over a year of dentist-recommended quarterly changes. Compatible with all Oral-B electric handles except Pulsonic and iO models.
Best for: Adult everyday use, most Oral-B electric handles (not iO or Pulsonic).
Pack: 5 heads | Technology: CleanMaximiser colour-change indicator, 16° angled bristles | Plaque removal: Up to 100% more vs manual
2. Oral-B Pro Kids Electric Toothbrush Heads – Spiderman Soft, 8 Pack
£44.99
The Pro Kids Spiderman 8-Pack is designed specifically for children aged 3 and up. The round brush head is sized for small mouths, and the extra soft bristles are gentle on young gums while still delivering a thorough clean. The Spiderman design turns brushing into a daily adventure rather than a battle — a small detail that makes a real difference to children who resist their routine. Eight heads per pack is exceptional value, covering two full years of quarterly replacements. Compatible with all Oral-B Pro Kids electric toothbrushes.
Best for: Children aged 3+, Oral-B Pro Kids electric toothbrushes, making brushing fun.
Pack: 8 heads | Bristles: Extra soft | Head size: Small (designed for children's mouths) | Design: Spiderman
3. Oral-B iO Ultimate Clean Replacement Heads – Black, 4 Pack
£42.75
The iO Ultimate Clean 4-Pack is the premium option — designed exclusively for Oral-B's iO system, the brand's most advanced electric toothbrush range. The signature round head features twisted, angled bristles that surround each tooth individually for a deeper, more precise clean than standard heads can achieve. The result is a professional-level clean from day one, every day. The sleek black finish matches the premium aesthetic of the iO handle. Four heads covers a full year of quarterly replacements. Note: these heads are only compatible with Oral-B iO toothbrushes — they will not fit standard Oral-B handles.
Best for: Oral-B iO toothbrush owners, those wanting the deepest possible clean, premium oral care routines.
Pack: 4 heads | Technology: Twisted angled bristles, surrounds each tooth | Compatibility: Oral-B iO only | Colour: Black

Which Oral-B Head Is Right for You?
The most important factor is compatibility — always check your toothbrush model before buying. If you have a standard Oral-B electric handle (not iO or Pulsonic), the CrossAction 5-Pack at £42.00 is the reliable everyday choice with the handy CleanMaximiser colour-change reminder built in. If you're buying for a child aged 3+ with an Oral-B Pro Kids brush, the Spiderman 8-Pack at £44.99 is exceptional value at two years' worth of heads, with a design that makes brushing something kids actually look forward to. And if you own an Oral-B iO toothbrush, the iO Ultimate Clean 4-Pack at £42.75 is the only head that unlocks the full performance of your brush — the twisted bristle design delivers a noticeably deeper clean that standard heads simply can't match.
