You can bring your Oral-B electric toothbrush to an approved recycling or disposing location in accordance with local regulations. You can locate your nearest recycling centre through the Recycle More website, which will tell you where your nearest recycling centre is for different items.
More stores are starting to offer recycling options for your used oral-care product packaging so ask or keep an eye out when in-store, for example Boots now have the option to recycle your brush heads and paste tubes in store.
