Replacing an Oral-B iO brush head might seem straightforward. However, a few details can make the difference between a well-considered purchase and an unnecessary expense. If you have sensitive teeth or gums, be sure to check the softness of the bristles, compatibility with your handle, and the number of brush heads included in the pack.
Oral-B iO Gentle Care replacement brush heads are designed for handles in the iO range. They are not compatible with Oral-B brush heads intended for the Pro, Smart, Genius or Vitality series.
At first glance, the outer shape may look similar. However, the attachment system is different. An Oral-B refill designed for a Pro series model will not necessarily fit an iO handle. Forcing it on risks damaging the brush head or the handle.
So check that the product listing clearly states “compatible with Oral-B iO only”. This is the first criterion to verify, before the colour or the number of heads in the pack.
A soft brush head is about more than just its marketing name. Also look at the composition and arrangement of the bristles: rounded tips, extra-soft bristles, or an outer ring designed to reduce pressure on the gums.
The Oral-B iO refills for sensitive teeth and gums from the Gentle Care range combine soft bristles with a round head. However, the sensation can vary depending on the pressure you apply, the brushing mode you select, and your individual sensitivity.
A pack of six Oral-B iO heads lets you space out your purchases, provided you can store the refills in a clean, dry place. A head should generally be replaced every three months, or sooner if the bristles become deformed, frayed, or if the wear indicator signals it.
A pack of three Oral-B iO heads can be a better choice for testing the softness of the Gentle Care range before building up a stock.
The original Oral-B iO heads shown here are exclusively for Oral-B iO handles. Before placing an order, identify the series indicated on the handle or on the charging base. Oral-B Pro Cross Action models, for example, are not compatible with iO handles.
To fit the new head, remove the old one, align the brush head with the metal shaft, then push it down vertically until the gap between the head and the handle disappears. It must be properly locked in place before switching on.
Soft Oral-B iO brush heads from the Gentle Care range feature a round head and bristles with rounded tips. This design allows you to clean each tooth individually, while the density of the bristles ensures consistent contact with the tooth surface.
If your teeth or gums are sensitive, choose:
These features are not a substitute for your dentist’s advice. If you experience persistent irritation or unusual bleeding, consult a healthcare professional.
Some round Oral-B iO brush heads have bristles whose colour fades gradually with use. This bristle wear indicator provides a visual cue for when to change the head.
Depending on the handle model and the refill used, a chip may also be recognised by the iO system and help track replacement. This feature does not replace regular inspection of the brush head: damaged bristles warrant an immediate change.
Why this choice suits this profile: The pack of three heads lets you try the Gentle Care range and last several months without buying a large quantity.
The listing states exclusive compatibility with Oral-B iO, DuPont extra-soft bristles with rounded tips, and a chip recognised by iO handles.
A black round head, three units and extra-soft bristles for a gentle daily routine.
Why this choice suits this profile: The pack of six is ideal for regular use and avoids multiple orders, while offering a discreet white finish.
The reference confirms exclusive compatibility with Oral-B iO, the presence of soft bristles, and wear tracking via the compatible handle.
Six white heads, a round shape, up to 4,000 soft bristles and a colour indicator.
Why this choice suits this profile: This pack of six refills is ideal for households that prefer to always have several heads on hand, especially in case of early replacement.
The reference clearly mentions the Gentle Care range, the round shape, ultra-fine bristles and the replacement indicator.
A pack of six heads, soft bristles, gentle daily cleaning and a visual cue for replacement.
We have prepared a complete, real-time updated selection of products that meet these exacting criteria, while complying with European safety regulations.
No. They are intended for handles in the Oral-B iO range only. The Pro, Smart, Genius and Vitality series use a different attachment system.
The usual guideline is around three months. Change it sooner if the bristles become deformed, frayed, or if the wear indicator changes colour. On compatible models, the handle may also display an alert.
The pack of six can lower the price per head, but always compare the unit price at the time of purchase. The pack of three is better for a first order or to check your comfort before building up a stock.
