Changing a brush head seems simple. Yet a compatibility error can turn a purchase into an unusable accessory. For users of an Oral-B iO electric toothbrush, the references differ by head shape, bristle softness, number of brush heads in the pack and recommended age.
Here are the most common pitfalls to avoid before choosing your Oral-B iO brush heads.
Oral-B heads designed for the Pro, Smart, Genius or Vitality ranges are not necessarily compatible with an iO handle. The attachment and drive system differ. A brush head may therefore look identical at first glance without actually fitting your device.
Before ordering, check that the product page clearly states "compatible with Oral-B iO". This precaution also applies to the Oral-B iO2 electric toothbrush, which must use heads from the iO range.
A pack of 6 may lower the price per brush head, but this format is not necessarily the most suitable for a single person or for someone who wants to test the feel of the bristles first. Conversely, a pack of 3 works well for a first purchase, giving roughly nine months of use with a replacement every three months.
Compare the price per brush head, any manufacturing date indicated on the packaging and, above all, your actual needs.
Soft bristles are generally designed to offer a more comfortable contact, but tolerance varies from person to person. Too much pressure, overly vigorous brushing or a worn brush head can still cause discomfort. If irritation persists or you notice unusual bleeding, seek advice from a dentist.
The Oral-B iO only label must be clearly visible. The models shown here use an attachment designed for iO handles. To fit a brush head, push it vertically until it clicks firmly into place, with no visible gap between the head and the handle.
Never force an iO head onto an Oral-B handle that is not from the iO range. You risk damaging the part and injuring yourself.
If you are looking for brush heads for sensitive gums, the Oral-B iO Gentle Care range offers, depending on the reference, soft or ultra-thin bristles. Their rounded profile and density are designed for gentler daily cleaning.
The Oral-B iO Ultimate Clean range, on the other hand, features a two-layer arrangement with bristles angled differently. It is aimed more at users who enjoy a more pronounced cleaning sensation, provided you remain gentle on teeth and gums.
Most manufacturers recommend replacing the brush head approximately every three months, or sooner if the bristles splay, fray or become deformed. Some references include indicator bristles whose colour gradually fades. This marker is handy, but regular visual checks are still useful.
Rinse the head after each use and let it air dry. Do not bite it, chew it or immerse it in very hot water.
Why this choice suits this profile: This format lets you try the soft bristles and keep a supply for several months, without investing in a large pack straight away.
The product page specifies exclusive compatibility with Oral-B iO handles and recommends replacement every three months.
Pack of 3, soft bristles, round head and wear indicator.
Why this choice suits this profile: This large pack is ideal for regular users who want to plan several replacements ahead while keeping the same reference.
The reference is clearly reserved for iO handles. It includes a wear indicator and a chip recognised by certain iO handles.
Pack of 6, dual-layer bristles and round head.
Why this choice suits this profile: This pack is suitable for a household with one or more iO handles, especially when brush head changes are planned in advance.
The stated softness, replacement indicator and iO compatibility are detailed on the product page, making comparison easy.
Six heads, ultra-thin bristles and Gentle Care profile for gentler brushing.
Why this choice suits this profile: The small round head and extra-soft bristles are designed for children aged 6 and over, under adult supervision.
The product page states the minimum age, exclusive compatibility with the iO range and the need for adult installation.
Three brush heads, extra-soft bristles and a format suitable for children aged 6 and over.

No, compatibility is not universal. iO heads are designed for Oral-B iO handles. For a brush from the Pro, Smart, Genius or Vitality ranges, look for the reference that matches your specific product family.
The generally recommended frequency is approximately three months. Replace it sooner if the bristles splay, fray or if the head has been damaged. On certain references, the indicator bristles gradually change colour to help you track wear.
The Oral-B iO Gentle Care models are equipped, depending on the reference, with soft or ultra-thin bristles. Start with light pressure and observe how you feel. If discomfort persists, it is better to seek advice from a healthcare professional rather than simply changing the brush head.
