A new set of electric toothbrush heads may seem simple to choose. Yet many people end up with the wrong product because they haven’t checked the connection, bristle firmness or intended use. A low price is little help if the brush head won’t fit your handle or feels uncomfortable after a short time.
Oral-B and Philips Sonicare use different systems. For example, a standard Oral-B brush head won’t fit an Oral-B iO handle. Philips Sonicare brush heads use a click-on connection, but there are exceptions, such as Philips One.
So always check:
Also check compatible brush heads from other brands. These may fit certain Oral-B models, but not necessarily iO, Sonic or Pulsonic handles.
Manufacturers sometimes quote percentages for plaque removal, whiter teeth or healthier gums. These figures don’t guarantee the same results for everyone. Make sure claims are attributed to their source: according to the brand’s own research or the product description.
Also look for details you can verify, such as:
A 2-pack may seem like good value, while a pack of 4, 6 or 8 brush heads may cost less per head. On the other hand, there’s no need to stock up if you’re not yet sure whether you’ll find the bristle firmness comfortable.
Most product descriptions recommend replacing brush heads after about three months, or sooner if the bristles fray, discolour or become damaged. Don’t share a brush head with anyone else.
With Oral-B brush heads, it’s important to distinguish between standard Oral-B handles and Oral-B iO. According to the stated product specifications, CrossAction, Precision Clean and Pro Deep Cleaning models are designed for standard rechargeable Oral-B handles and aren’t compatible with iO.
Oral-B iO brush heads, by contrast, are exclusively for iO handles. Don’t force an iO brush head onto a Pro, Smart or Genius handle.
For Philips Sonicare brush heads, check whether it’s a click-on model and whether your handle is included in the Sonicare series listed. The HX6066/87 Optimal White, for example, isn’t compatible with Philips One. The product information describes the HX6014/87 ProResults as compatible with Sonicare handles.
Soft brush heads are a practical choice if you prefer a gentler brushing experience. According to the product specifications, Philips Sonicare A3 has soft bristles and flexible rubber sides. Oral-B iO Gentle Care features a high number of soft bristles and a gentle outer ring.
A round head, as found on many Oral-B models, works tooth by tooth. An oval Sonicare head moves differently across the surface of your teeth. Neither shape is automatically right for everyone: comfort, handle compatibility and brushing habits all matter.
A fading indicator makes it easier to know when it’s time to replace your brush head. On some Oral-B models, the indicator bristles change from green to yellow. On certain Philips Sonicare models, blue bristles fade to white. Treat this as a practical reminder, not a medical measurement.

We’ve put together a complete, up-to-date list of products that meet these strict selection criteria and the applicable European safety regulations.
Many manufacturers recommend replacing them about every three months. Replace them sooner if the bristles fray or bend, or if the colour indicator shows that it’s time. With frequent use, signs of wear may appear sooner.
No. According to the product specifications, standard Oral-B brush heads are often not compatible with iO, Sonic or Pulsonic models. Oral-B iO brush heads are designed specifically for iO handles. Check your model before ordering.
It depends on the specifications and fit. Check the connection, bristle firmness, pack size and replacement indicator. A compatible brush head may offer good value, but only use one if the product information clearly lists your handle model.
