The Oral-B iO electric toothbrush is a popular choice for many consumers due to its advanced features and technology. However, if you’ve noticed a yellow light glowing on the Mode button of your Oral-B iO after use, you may be wondering what it means and how to address it.
The yellow light on the Mode button is a signal from your iO that it’s time to replace the toothbrush head. Typically, this occurs around three months of use, as older brush heads can lose their effectiveness in cleaning your teeth. You may also notice signs such as splayed bristles or faded bristle color, indicating the need for a new brush head.
To reset the brush reminder after replacing the brush head, simply press and hold the Mode button for two seconds on the handle. The brush will vibrate in response, confirming the reset. If you have an app-connected iO, you can also set up a reminder in the Oral-B app by accessing the “Devices” section and syncing your iO to the app.
By following these steps, you can ensure that your Oral-B iO continues to provide optimal cleaning performance.

With the right care and maintenance, your Oral-B iO can help you achieve a healthy and bright smile for years to come.
