The best Oral-B iO replacement heads are genuine Oral-B iO Ultimate Clean heads, because both packs fit iO Series handles and use a round, tooth-by-tooth design. The other 12-pack and 8-pack options here support selected other Oral-B handles, with no confirmed iO compatibility.
For an iO handle, choose a refill that explicitly supports the iO Series. Don't assume a head that fits a Pro, Smart, Genius or Vitality handle will also fit an iO.

How we chose these Oral-B iO replacement heads
Our scores weigh compatibility, bristle features and pack contents against what you need from a replacement head. We compared the supported handle families, head designs and replacement guidance for each option.
Compatibility is the first filter. The genuine Oral-B heads explicitly fit iO Series rechargeable handles, GottaShine and NEDIFON exclude iO, and GENKENT does not confirm iO fit.
For an additional handle-by-handle overview, see which brush heads fit Oral-B and Sonicare handles.
Pack size is a practical second choice. The genuine options come in 2- and 4-head packs, while the other options offer 8 or 12 heads.
A bigger pack only helps if it fits your handle.
Compare Oral-B iO replacement heads
The two genuine Oral-B options are the only confirmed iO choices in this roundup. The other three offer more heads or different styles for selected other Oral-B models.

1. Oral-B iO Ultimate Clean Heads: 2 white refills
Oral-B iO Ultimate Clean Heads: Best for genuine iO refills
- Fits Oral-B iO Series rechargeable handles
- Round head with angled bristles
- Color-changing bristles signal replacement
The genuine Oral-B refill fits an iO handle. Its round head has angled bristles, and the bristles change color to signal when to replace the head.
Pros
- Genuine Oral-B iO head
- Color-changing replacement cue
- Round, tooth-by-tooth design
Cons
- Not compatible with Oral-B Pro, Smart or Genius handles
- 2 heads per pack
Oral-B's 2-count Ultimate Clean refill is our top pick for an iO handle. Its round head and angled bristles are designed for tooth-by-tooth coverage, and the bristles change color to signal when it's time to replace the head.
These heads fit Oral-B iO Series rechargeable handles, not Oral-B Pro, Smart or Genius handles. The handle family is the key check before buying, even if your current brush is also an Oral-B.
Oral-B claims these heads remove up to 100% more plaque than a regular manual toothbrush. That comparison does not guarantee better cleaning than the other replacement heads in this guide.
Choose this pack if you want the color-changing bristle cue and need two genuine iO refills. If you'd rather keep more heads on hand, compare it with the 4-pack below.
2. Oral-B iO Ultimate Clean Heads, 4-Pack: 4 black refills
Oral-B iO Ultimate Clean Heads, 4-Pack: Best for stocking up on genuine heads
- Fits Oral-B iO Series handles only
- Round head design
- Four genuine replacement heads
This genuine Oral-B option provides four individually packaged iO Ultimate Clean heads. Choose it if you want several refills ready in one pack.
Pros
- Four genuine iO heads
- Individually packaged
- Clear 3-month replacement guidance
Cons
- Not compatible with non-iO Oral-B handles
- Larger pack than the 2-count option
This pack contains four genuine black Oral-B iO Ultimate Clean heads, each individually packaged. It suits iO owners who want more refills in one pack.
The round head is designed for iO Series handles only. Oral-B recommends replacement every 3 months, giving you a simple schedule for changing heads.
Both genuine options fit iO Series handles, but the pack sizes and colors differ. The 2-count option also has a confirmed color-changing bristle cue.
See our guide on how to change an Oral-B brush head if you need help with the replacement process.
Pick this pack if you prefer four individually packaged genuine refills. It doesn't fit Pro, Smart or Genius handles.
3. GENKENT Compatible Heads, 12-Pack: Color rings for identification
GENKENT Compatible Heads, 12-Pack: Best for compatible non-iO handles
- 12 heads with four color rings
- Fits selected Oral-B models
- Angled bristles
GENKENT offers a larger refill pack for selected Oral-B handles, including several Pro and Vitality models. iO compatibility is not confirmed, so choose it only for a supported handle.
Pros
- 12 heads in the pack
- Four color rings help identify heads
- Supports several Pro and Vitality models
Cons
- No confirmed iO compatibility
- Compatibility depends on the handle model
GENKENT's 12-pack supports selected Oral-B models, including several Pro and Vitality handles. The pack has four color rings to help household members identify their own heads.
GENKENT describes its bristles as soft and flexible. The angled bristles are designed to reach between teeth and along the gumline.
Supported models include Pro 1000, Pro 3000, Vitality Precision Clean, Triumph and Professional Care. iO compatibility is not confirmed, so choose a genuine iO option for an iO handle.
Check the exact model rather than relying on the Oral-B brand name alone. A broad family name can be less useful than the model number on your handle.
Choose GENKENT when your handle matches and the 12-head quantity and color rings suit your household. Keep each person's head separate rather than sharing a single head.
4. GottaShine Compatible Heads, 12-Pack: Daily Clean and Deep Clean
GottaShine Compatible Heads, 12-Pack: Best for mixed daily and deep-clean styles
- 12 heads: 9 Daily Clean and 3 Deep Clean
- Fits selected Oral-B click-on handles
- Medium-firm bristles
The mix of Daily Clean and Deep Clean heads gives compatible non-iO handle owners two styles in one pack. These heads do not fit iO or Pulsonic handles.
Pros
- Two head styles in one pack
- 12 heads total
- Medium-firm bristles
Cons
- Not compatible with iO or Pulsonic
- Compatibility is limited to selected handle families
GottaShine's pack includes 9 Daily Clean heads and 3 Deep Clean heads for selected Oral-B click-on handles. GottaShine describes the bristles as medium-firm, with extra-long interdental bristles on the Deep Clean style.
These heads do not fit iO or Pulsonic. Supported families include Pro, Smart, Genius, Vitality, Triumph and Professional Care.
GottaShine describes Daily Clean as its everyday brushing option and Deep Clean as a design for reaching between teeth and along the gumline. Those style names don't guarantee better results than the other heads here.
The mixed pack gives you two designs in one refill supply. Choose it if you want both styles and your handle belongs to a supported family.
For an iO handle, choose one of the genuine refills above. The larger pack does not make this an alternative for an incompatible handle.
5. NEDIFON Compatible Heads, 8-Pack: Individually packaged refills
NEDIFON Compatible Heads, 8-Pack: Best for individually packed non-iO refills
- Eight individually packaged heads
- Four color rings
- Fits selected Oral-B rechargeable handles
NEDIFON provides eight individually packaged heads for selected Oral-B non-iO handles. They do not fit iO or Pulsonic, so confirm your handle before buying.
Pros
- Individually packaged heads
- Four color rings
- Eight heads in one pack
Cons
- Not compatible with iO or Pulsonic
- Compatibility varies by handle model
NEDIFON's 8-pack contains individually packaged Precision Clean heads, with four color rings for identification. NEDIFON describes longer, softer outer bristles and shorter, denser inner bristles.
These heads fit selected Oral-B rechargeable handles, including Vitality Precision Clean, Professional Care, Triumph and Sensitive Clean models. NEDIFON excludes iO, Pulsonic, Vitality Sonic, Sonic Complete and CrossAction Power.
Choose this pack if you want individually packaged heads and your handle matches a supported model. The 8-head pack contains fewer refills than the GENKENT and GottaShine options.
The color rings help distinguish household members' heads. Individual packaging also lets you open one refill while leaving the others wrapped.
For cleaning and care after fitting a new head, read how to clean an electric toothbrush handle and head. That guide covers routine care for both parts.
How do you choose the right iO head?
Start with the exact handle family, then choose a refill that explicitly supports it. For Oral-B iO Series handles, the two genuine Oral-B Ultimate Clean packs are the matching choices here.
Choose between the 2-count and 4-pack based on how many refills you want, their color and the 2-count option's confirmed color-changing bristles. Don't assume the 4-pack lacks that feature simply because it isn't confirmed here.
For another Oral-B handle, compare its exact model with the supported models for GENKENT, GottaShine or NEDIFON. GottaShine and NEDIFON explicitly exclude iO, while GENKENT does not confirm iO compatibility.
If you're choosing a new handle, our best Oral-B electric toothbrushes guide compares toothbrush options. You can also read Oral-B vs Sonicare for a broader brand comparison.
When should you replace an iO brush head?
Oral-B recommends replacing Ultimate Clean heads every 3 months, or sooner if worn. The color-changing bristles on the 2-count option provide an additional visual cue.
Don't wait for a calendar date if the head becomes visibly worn sooner. For more detail on timing, see our guide to how often you should replace an electric toothbrush head.
Which Oral-B iO replacement heads should you buy?
Choose the 2-count Oral-B Ultimate Clean for two white genuine iO heads with a color-change cue, or the 4-pack for four individually packaged black refills. For another Oral-B handle, match GENKENT, GottaShine or NEDIFON to its exact model before ordering.
If you're still choosing a toothbrush, start with our best electric toothbrushes for adults guide, then confirm which replacement heads fit your chosen handle.
