What Does a Yellow Light on My Oral-B iO Mean and How Can I Fix It?

If you recently purchased an Oral-B iO toothbrush, you may have noticed a yellow glow on the Mode button after using it for some time. While this may seem concerning, there is a simple explanation for this indicator and a straightforward solution to address it.

The yellow light on your Oral-B iO brush is a helpful reminder that it’s time to replace your toothbrush head. Typically, after around three months of use, the effectiveness of the brush head starts to diminish, and it may not clean your teeth as efficiently as before. You can also tell it’s time for a replacement if the bristles have become frayed or if the color of the bristles has faded.

To reset the brush reminder after replacing the brush head, simply press and hold the Mode button on the handle for two seconds. The brush will vibrate to confirm that the reminder has been reset. If you have an app-connected iO toothbrush, you can also set up a reminder in the Oral-B app. Navigate to the “Devices” section in the app, sync your toothbrush with the app, and follow the prompts to input information about the new brush head. This will ensure you receive another reminder in three months’ time.

The Oral-B iO toothbrush offers various feedback features, including quadrant alerts, a two-minute brushing timer, and a pressure sensor that indicates when you’re brushing too hard. The yellow light on the Mode button serves as a helpful reminder to maintain optimal oral hygiene by regularly replacing your brush head.
