What does the red light on my Oral-B electric toothbrush mean?

A red light on your Oral-B electric toothbrush could be one of three things:

Many of our toothbrushes (PRO 2000 and above) include a visible pressure sensor. If pressing too hard on the teeth, it will light up. We recommend only very lightly pressing the brush to the teeth, and letting the toothbrush itself do the work.

Is the pressure sensor lit up all the time? Sometimes, a bit of toothpaste can get stuck around the metal pin which connects to the brush head, and this can trip the pressure sensor. To fix this, try rinsing the metal pin and handle under warm water for at least ten seconds. To prevent this in future, always make sure after every use to remove the replaceable brush head and rinse both parts separately and thoroughly, before drying both parts and storing them for next use.

If the red light is nearer the bottom of the handle, this could be the low battery indicator (PRO 1000 and above). This lights up when it’s time to charge your toothbrush, as there is only juice left in the battery for 1 or 2 more brushes. Now would be a good time to charge it.

Is the low-battery indicator lit up on a freshly charged toothbrush, or always on? Please have a look at this question, as it sounds like the toothbrush might not be charging correctly.

Lastly, our new Genius toothbrushes include a Customizable Smart Ring, used to track the toothbrush’s position on our Oral-B App. Using the App, you can change the color of this ring, and there are a number of colors to choose from.

If none of this helps, please get in touch. If you can give me a little bit more information about the red light you are seeing on your toothbrush, I may be able to assist further! You can contact our team by emailing us on our website.
