Is your electric toothbrush losing its effectiveness? Are the bristles on the head frayed or faded? That's a sure sign it's time for a change. Choosing the right replacement brush head is the key to impeccable oral hygiene. But with the jungle of options for Oral-B or Philips Sonicare, it's easy to get lost.
This guide is here to help you see things more clearly and find the electric toothbrush head that not only fits your brush but also meets your specific needs—whether you're looking to achieve whiter teeth, care for your gums, or tackle plaque in every nook and cranny.
To make the right choice, you need to consider three criteria. They will ensure not only an effective brushing experience but also the longevity of your device.
This is the essential starting point: verifying that the brush head is compatible with your toothbrush handle. Manufacturers use proprietary attachment systems that are rarely interchangeable between brands, and sometimes not even within the same product line.
A simple tip: before buying any toothbrush refill, take a look at the series name, which is usually written on the handle or the original box.
Once you've confirmed compatibility, the choice of head depends on your personal goals:
Dentists and manufacturers are unanimous: a brush head should be replaced every three months, no longer. Beyond that, the bristles fray, lose their effectiveness, and worse, can become breeding grounds for bacteria.
To help you remember, most modern brush heads include a wear indicator: coloured bristles that fade as you brush, signalling that it's time for a replacement. The most advanced models, connected to an app, will even send you a notification so you never miss the right time.
To guide you, here is our selection of the best current options for Oral-B and Philips Sonicare users.

The golden rule: every three months. You should also change it immediately if the bristles are frayed or after you've recovered from an illness (flu, cold, etc.).
The easiest way is to check the model name of your toothbrush, often written on the bottom of the handle (e.g., Oral-B iO, Philips Sonicare DiamondClean). This reference will ensure you don't make a mistake. If in doubt, our product pages always list the compatibilities precisely.
Not at all! They are simply different. A brush head for sensitive gums uses ultra-soft bristles to clean effectively without irritating the tissue. Plaque removal remains excellent, but the action is much gentler, which is ideal for people prone to bleeding or irritation.
