How to Change Brush Head on Sonicare Toothbrush

Keeping your Philips Sonicare toothbrush in good shape is essential if you want to get the best cleaning potential out of the brush.

It’s important to replace the brush head periodically. Philips says you should replace it about every 3 months, or even more frequently if it wears out. On most Sonicare toothbrushes, you’ll know it’s time to replace the brush head when the indicator light blinks amber (it looks like a little brush head with arrows around it.)

For this tutorial, we’ll be looking at the steps for changing the brush head. Here’s a video that I made demonstrating that process with my own Sonicare 4100 brush.

Remove the Old Brush Head

The first step is to pop off the old brush head that you want to get rid of. Just give it a solid pull, and it should pop off the brush.

Beware–you might be shocked to see how much gunk has accumulated under the brush head! Now is a perfect time to get a bit of rubbing alcohol and clean that gunk off before adding in a new head.

Now, get your new brush head ready. Depending on the model, you’ll need to choose the brush head that matches it. These are the ones I use.

Adding the New Brush Head

Now we just want to pop the new one back on. Even after you do this, the indicator light will still be blinking to show it’s time for a replacement.

To reset the Brush Replacement indicator light, place the toothbrush on its charger and hold the power button for five seconds. It will pulse three times, which lets you know it is reset.

Changing the brush head on the Philips Sonicare toothbrush may seem intimidating, but it doesn’t have to be.
