Toothbrush Heads Price Comparison

Replacement toothbrush heads are one of those purchases that looks simple on the surface — until you're standing in the dental aisle wondering whether your Oral-B handle takes a CrossAction or an iO head. Compatibility is everything here, and getting it wrong means an unusable product. The good news: once you know your handle series, the choice becomes much more interesting.

Oral-B dominates this category with 148 products at an average of around 17 £, covering everything from budget 4-packs to premium iO heads. Philips Sonicare comes in as the clear premium alternative — 103 products but a noticeably higher average price, reflecting the brand's focus on sonic vibration technology. What's striking is the price spread: you can find a perfectly decent 4-pack starting from 9 £, while specialist heads for the iO series or Sonicare ProResults can push well over 21 £. That gap isn't just about brand prestige — it reflects genuine differences in bristle density, cleaning technology, and pack size.

For most households, the sweet spot sits between 10 £ and 15 £. That range covers multi-packs from both Oral-B and Philips with proper wear indicators — those colour-fading bristles that tell you it's time to swap. Dentists recommend replacing heads every three months, so buying an 8-pack makes real financial sense compared to picking up a 2-pack every quarter. Our data shows the 8-pack CrossAction and Sonicare W2 are among the most-compared products in this category, which tracks with that logic.

Beyond the two giants, it's worth knowing that other toothbrush accessories like Waterpik heads and Panasonic replacements are also well represented. If you're shopping for a child, Brush-Baby offers heads from as little as 9 £, and Oral-B's Kids Pro range sits comfortably under 10 £. For those with sensitive gums, the Oral-B Sensitive and Curaprox lines are worth comparing directly — the bristle softness varies considerably between them. And if you're in the market for a new handle altogether, checking out electric toothbrushes alongside the heads can save you money on bundle deals from Currys or Amazon.co.uk, particularly around Black Friday and the January sales.

One thing we'd flag: third-party compatible heads are widely available and significantly cheaper, but quality control is inconsistent. Some work perfectly well; others wear out in weeks or cause the handle's pressure sensor to misfire. For Oral-B iO handles in particular, we'd stick to genuine heads — the magnetic drive system is fussy about fit. For older Oral-B round-head handles, the compatibility is broader and third-party options are more reliable. Browse the full accessories range to compare prices across merchants before committing.

How to Choose the Right Toothbrush Head

With 291 heads listed across a price range that stretches from 9 £ to 28 £, the hardest part isn't finding a deal — it's knowing which head actually fits your handle and suits your teeth. Here's what genuinely matters.

Handle compatibility — the non-negotiable first step

Before anything else, check your handle's series. Oral-B round-head handles (Pro, Smart, Genius, Vitality) all share the same fitting and accept CrossAction, 3D White, Sensitive, and Deep Cleaning heads interchangeably. The Oral-B iO series is entirely different — it uses a magnetic drive and only accepts iO-specific heads, which cost noticeably more (typically over 15 £ for a 2-pack). Philips Sonicare heads use a click-on system, but compatibility varies by series: C-series heads work across most modern Sonicare handles, while older E-series handles have limited options. If in doubt, check the model number on the back of your handle before buying.

Cleaning specialisation — match the head to your actual needs

Manufacturers offer distinct head types for good reason. CrossAction (Oral-B) and W2 Optimal White (Philips) are the all-rounders — solid plaque removal for everyday use. 3D White heads use a slightly abrasive cup shape to polish enamel; fine for occasional whitening, but not ideal for daily use on sensitive teeth. Sensitive heads have softer, more flexible bristles — genuinely useful if your gums bleed easily or you've had recent dental work. Deep Cleaning heads feature higher bristle density for a more thorough clean along the gumline. Kids' heads (Oral-B Kids Pro, Brush-Baby) are smaller and softer — don't skip this if buying for a child under 10.

Pack size and cost per head

This is where the real savings are. A 2-pack might look cheap at first glance, but the per-head cost is almost always higher than a 4- or 8-pack. At the recommended replacement frequency of every 3 months, a household of two adults needs at least 8 heads per year. An 8-pack of Oral-B CrossAction or Philips Sonicare W2 typically brings the per-head cost down significantly compared to buying 2-packs repeatedly. Packs over 21 £ are almost exclusively 8-packs or larger — worth the upfront spend if you're stocking up.

Bristle wear indicators

Most mid-range and premium heads include colour-fade indicators — bristles that are blue when new and fade to white when it's time to replace. It sounds like a gimmick, but it's genuinely useful: worn bristles lose up to 30% of their cleaning effectiveness before they look visibly splayed. Budget heads and some third-party options omit this feature entirely. If you tend to forget to replace your head, prioritise heads with a clear indicator — it's a small detail that makes a real difference to oral health outcomes.

Genuine vs. compatible third-party heads

Third-party heads compatible with Oral-B and Sonicare handles are widely sold on Amazon.co.uk and often cost a fraction of the genuine article. For standard Oral-B round-head handles, many third-party options perform acceptably — the fitting is simple and the technology straightforward. For Oral-B iO handles, we'd strongly advise against third-party heads: the magnetic drive system is precision-engineered, and off-brand heads frequently trigger error messages or deliver noticeably worse cleaning. For Sonicare, the sonic frequency is handle-generated, so compatible heads can work — but bristle quality varies wildly. Stick to genuine heads if you're spending over 15 £ on a handle.

• Budget picks (From 9 £ to 10 £) : Mostly 2- and 4-packs from Oral-B's standard range (CrossAction, 3D White, Sensitive) and children's heads from Brush-Baby. Perfectly functional for older Oral-B round-head handles. Wear indicators are sometimes absent at this price. Good for stocking up on kids' heads or trialling a new head type before committing to a larger pack.
• The sweet spot (From 10 £ to 15 £) : This is where most shoppers should be looking. Covers Oral-B 4- and 8-packs with CleanMaximiser wear indicators, entry-level Philips Sonicare heads, and Panasonic replacements. Braun Pulsonic heads also sit in this range. Solid quality, genuine compatibility, and enough heads to last 6–12 months for a single user.
• Premium multi-packs (From 15 £ to 21 £) : Philips Sonicare W2 and ProResults 8-packs, Oral-B iO heads, and Oclean replacements. At this level you're getting higher bristle density, better sonic performance, and often a full year's supply in one purchase. Oral-B iO Ultimate Clean heads fall here — worth it if you own an iO handle, but pointless otherwise.
• Professional and specialist heads (Over 21 £) : Large-format packs (12- and 16-packs), Braun premium heads, and specialist Philips Sonicare ProResults bundles. Also where you'll find Curaprox and some Silk'n heads. Typically bought by dental-conscious households stocking up for the year, or professionals. The per-head cost is usually excellent — but only makes sense if you're confident in the compatibility.

Top products

• Oral-B CrossAction 4 pc(s) White (Oral-B) : The most-compared head in the category for good reason — versatile, compatible with virtually every standard Oral-B handle, and genuinely effective at plaque removal. The 4-pack is the sensible entry point, though the 8-pack CrossAction Black works out cheaper per head.
• Philips Sonicare W2 Optimal White HX6068/13 8-pack sonic toothbrush heads (Philips) : The best value Sonicare option if you're stocking up — an 8-pack brings the per-head cost down to a level that rivals Oral-B. The W2 bristle configuration handles both whitening and everyday cleaning well. Only relevant if you own a compatible Sonicare handle, obviously.
• Oral-B CrossAction 8 pc(s) Black (Oral-B) : The smarter bulk buy over the 4-pack White — lower per-head cost and enough supply for a full year for one person. The black colour coding is useful in multi-user households. Identical cleaning performance to the white version; the colour is purely cosmetic.
• Oral-B iO Ultimate Clean 4 pc(s) Black (Oral-B) : The premium pick for iO handle owners — the magnetic drive and higher bristle density deliver a noticeably superior clean compared to standard round heads. Expensive relative to the rest of the range, and completely pointless if you don't own an iO handle. Don't buy these by mistake.
• Oral-B Kids Pro 3+ 4 pc(s) White (Oral-B) : The standout choice for children aged 3 and up — smaller head size, softer bristles, and a price that makes regular replacement realistic. Works on any standard Oral-B round-head handle, so parents can share the same handle body. A genuinely useful product rather than just a repackaged adult head.
