We’re sorry to hear you’ve noticed a residue building up on your toothbrush. We have many quality checks in place to ensure only the best products reach you. Please know we understand this is unsightly but it is likely a buildup from regular use. Even if rinsed after each use, residual toothpaste can harden over time and form a residue on your toothbrush and the replacement head. This buildup may be colored depending on your toothpaste and water hardness. In either case, this substance is not harmful and can be removed with a thorough cleaning. So that we can help you further, please give us a call at (800) 566-7252.

As you can imagine, this isn't the experience we expect you to have with your brand new Oral-B iO, Pam. This is likely because it got into contact with an ingredient that is corrosive in nature and made the plastic porous. These things are found in things like soaps, cosmetics, and cleaning agents. You can clean the brush after each use and store the brush head and brush handle in a well ventilated and it should prevent this from happening in the future. For further assistance, please contact us by dialing (800) 566-7252.

We’re very sorry to hear this has been your experience with the Oral-B iO Series 9, and we genuinely hope your gums feel better soon. Our products go through extensive safety tests to ensure they are safe to use as directed, and your experience will be shared with our Safety team. If you haven’t already, we encourage you to discontinue use of the product. Please hold onto it for 2 weeks, in the case we may need to retrieve it from you. We'd like to help get you brushing with a new Oral-B toothbrush, so it may be helpful to know that in the first days of using any electric toothbrush, your gums may bleed slightly. In general, bleeding should stop after a few days. Should it persist after 2 weeks, please consult your dentist or dental hygienist. Additionally, gums may bleed if too much pressure is used. We encourage you to try to decrease the pressure and let the toothbrush do the work. If you have sensitive teeth and/or gums, we recommend using the Sensitive cleaning mode paired with our Sensitive brush head. So we can help you further, please call us at 1(800) 566-7252.
