We want you to be blown away with the amazing cleaning performance of our iO series 9 brushes, so we're so sorry to hear this wasn't your experience. We want our brushes to last for many years after rigorous quality testing which we stand behind with our Oral-B Money Back Guarantee, so we'd love to learn more. When you have a moment, we hope you'll give us a call at (800) 566-7252.

Maintaining a healthy smile is so important to us, Emmie, so we're very sorry to hear that your brush is no longer spinning. If you have not done so already, please try removing the brush head and rinse the parts under warm running water. There may be hardened toothpaste preventing the brush from moving as expected. We'd love to learn more about this and help you with your iO Series 9. Please call us at (800) 566-7252.

That doesn’t sound like the quality we expect from the Oral-B iO, and we’d like to learn more about what happened so we can help. Please know all of our rechargeable electric toothbrushes come with a two-year warranty, so give us a call at (800) 566-7252 and we’d be happy to assist.
