Why is my Oral-B iO Electric Toothbrush making rattling noise?
- RRyan CannonSep 12, 2025
A rattling or loud noise during brushing or when turning on your Oral-B Electric Toothbrush can be due to: 1. The brush head may not be placed correctly onto the brush handle. Check the proper fit of the brush head on the handle, noting that a small gap should remain in between. 2. The brush head may be worn. Replace the brush head.
