Anyone looking to buy Oral-B iO replacement brush heads will find numerous offers with similar product names. At first glance, the brush heads often appear to differ only in colour or pack size. In reality, however, bristle firmness, bristle design and exclusive iO compatibility are key factors when choosing the right product.
The Oral-B iO range uses its own connection system. Classic Oral-B replacement brush heads for other ranges are therefore not automatically compatible with an iO handle. Look for the clear wording “for Oral-B iO electric toothbrushes” or “Oral-B iO compatible”.
An Oral-B iO replacement brush heads pack of 8 lasts approximately two years with regular replacement if one person uses a new brush head every three months. For a first purchase, a pack of 4 may be more practical, allowing you to try the variant in everyday use first. A pack of 6 sits between the two in terms of quantity and is suitable for users who want to build up a supply.
Brush heads with a dense or angled bristle structure may feel different when brushing compared with particularly soft variants. If you have sensitive gums, the advertised cleaning performance should not be the only factor you consider. Soft bristles, controlled brushing technique and as little pressure as possible are crucial. If bleeding gums or discomfort persists, stop using the product and seek dental advice.
Original genuine Oral-B iO replacement brush heads are designed for iO handles. The product descriptions of the models selected here state that they are exclusively compatible with Oral-B iO electric toothbrushes. Nevertheless, check your handle and the information on the product page before buying.
A correctly fitting connection should click securely into place. A brush head that is loose, damaged or cannot be attached correctly should not be used.
For users looking for soft brush heads for sensitive gums, models from the Oral-B iO Gentle Care or Gentle Clean ranges are an obvious choice. According to the product information, these variants feature up to 4,000 soft bristles and a cushioned outer ring. These details describe the construction but do not constitute any medical claim.
The Oral-B iO Ultimate Clean range, on the other hand, uses angled CrissCross bristles, among other features. Several product variants specify an angle of 16 degrees. This design may appeal to users who value structured cleaning along the gumline and in hard-to-reach areas. Suitability depends on your personal brushing technique and how the brush feels in your mouth.
The product information recommends replacing the selected brush heads approximately every three months, or sooner if the bristles fray, come loose or become damaged. Some models feature colour-changing indicator bristles that can show when it is time for a replacement.
For budgeting purposes, you can simply work on the following basis:
This calculation assumes replacement every three months and does not take additional requirements into account, such as multiple users in the household.

We have put together a complete, regularly updated list of products that fully meet these strict selection criteria and the safety regulations applicable in the EU.
Rinse the brush head thoroughly under running water after every use. Where possible, allow the brush head and handle to dry separately. Do not share brush heads with other people. Before each use, check whether any bristles are loose or whether the head shows signs of damage.
The small parts are not suitable for children under three years of age due to the possible risk of swallowing. The adult variants featured here should not be confused with special Oral-B iO Kids brush heads.
The product information recommends replacing them approximately every three months. Earlier replacement is advisable if the bristles fray, come loose or the colour indicator has noticeably faded.
