Most Philips Sonicare brush heads fit click-on handles, but the three types covered here do not fit Philips One or e-series handles. Check your handle type before buying, especially if you have an older model or a compact Philips One brush.
The connection usually settles the fit question. Once you've confirmed your handle uses a click-on head, choose among head styles based on their intended cleaning focus.
Are Sonicare brush heads interchangeable across handles?
Yes, these Philips Sonicare replacement heads fit click-on Sonicare handles. Philips describes the C2, C3, and W DiamondClean replacement heads as compatible with click-on electric toothbrushes.
Philips says these heads do not fit Philips One or e-series handles. If you can't identify your handle's connection, check the model name or manual before ordering.
A matching connection does not mean every head has the same bristle pattern or cleaning focus. The head type can change what the brush is designed to emphasize, even when it clicks onto the same handle.
Which Sonicare handles need a different head?
Philips One and e-series handles are the stated exceptions for these click-on heads. Don't assume compatibility just because the handle carries the Sonicare name.
Look for the exact model printed on the handle or packaging, then check Philips' compatibility guidance for that model. This is especially useful when replacing a head on a brush someone else bought or on an older handle.

What are the main Sonicare replacement head types?
C2, C3, and W DiamondClean heads share the click-on connection but have different cleaning focuses. C2 is an everyday plaque-control head, C3 is designed for deep cleaning and stain removal, and W DiamondClean is aimed at stain removal.
Is the C2 Plaque Control head a general choice?
The C2 Plaque Control is an everyday head with a power tip designed to target plaque in hard-to-reach areas. Philips says its blue bristles turn white as they wear, and compatible BrushSync handles can signal when it's time to replace the head.
Choose C2 if you want a plaque-control focus without choosing a head centered on stain removal. It is not compatible with Philips One or e-series handles.
What is different about C3 Two-in-One?
The C3 Two-in-One has dense bristles in a central cluster, designed for deep cleaning and stain removal. Philips says the soft-touch back enhances bristle motion, and the head works with click-on Sonicare handles except Philips One and e-series.
Choose C3 if those features match what you want from a replacement head. If you're mainly deciding between handle models, compare the choices in our Sonicare models guide.
What does the W DiamondClean head do?
The W DiamondClean head uses a diamond-shaped bristle area and a central stain-removal pad. Philips says the design is intended to increase surface contact and remove stains, and the head fits click-on handles apart from Philips One and e-series.
Pick this style if you want a head designed around stain removal. It uses the same click-on fit described above, so check the handle connection before choosing it.
How do you choose the right replacement head?
First confirm the connection, then choose the head's cleaning focus. For a click-on handle, C2 emphasizes plaque control, C3 is designed for deep cleaning and stain removal, and W DiamondClean focuses on stain removal.
If you're unsure, find the handle model and verify compatibility before ordering. Don't rely on color or appearance alone, since those details don't confirm that a head will fit.

How often should you replace a Sonicare brush head?
Philips says dental professionals recommend changing brush heads every 3 months. On BrushSync-compatible handles, a reminder light can signal replacement time, and the blue bristles are designed to turn white as they wear.
BrushSync reminders are available only on compatible handles, so don't expect every Sonicare handle to show the same alert. You can still use the bristle color change as a visual cue on heads that include it.
Which Sonicare head should you pick?
Choose C2 if you want an everyday plaque-control head, C3 if its deep-clean and stain-removal focus suits you, or W DiamondClean if you want a central stain-removal pad. All three are for click-on handles, with Philips One and e-series excluded.
When fit is uncertain, check the handle model before buying. Then use the cleaning focus to narrow your choice.
