Preserve consulted closely with dental professionals to create a toothbrush that gets your teeth cleaner but minimizes your impact on the environment. The design includes a curved handle for those hard-to-reach places and a three-level bristle arrangement to massage your gums. And while the bristles are brand new, the handle is made from recycled yogurt cups. The toothbrush is completely recyclable in Preserve mail back system. The lightweight package doubles as a return envelope for recycling the toothbrush.
