We can certainly understand your disappointment, as we do have many quality checks in place to ensure that you can rely on our toothbrushes. We'd be happy to look into this further and see how we can best assist. When you have a chance, please give us a call at (800) 566-7252.

Melissa, we're so glad you enjoy the clean your iO 7 offers, and are sorry you notice mold on your toothbrush. Please know that there’s nothing in our toothbrush components that would cause mold before use. Mold requires organic material to grow, which isn’t present in our brushes. While it’s rare, mold can develop after use if the brush is stored in a damp area or comes into contact with certain cleaning agents or soaps that can make the plastic porous. So we can offer more help, please call us at (800) 566-7252.
