EARTH-FRIENDLY and EASY TO HANDLE: Thanks to replacement-head technology and a handle made from repurposed materials, the Source reduces waste by 93%. When you’re done with one of its patented, gum-stimulating heads you simply swap it for another. REPLACEABLE HEADS WITH PREMIUM BRISTLES: The Source cuts back on plastic usage while simultaneously boasting a unique curved bristle-bed, ensuring our sumptuously soft bristles clean and massage the gum rather than aggravating them. LONGER NECK FOR A BETTER REACH: The Source has an unbreakable slim neck that’s longer than your average toothbrush to provide maximum reach in tight spaces. UPCYCLED NATURAL-FEEL HANDLE: The elegant, one-of-a-kind handle is composed of repurposed and recycled materials — like wood, paper and even recycled dollar bills — for a beautiful, natural look and feel. REVERSIBLE HANDLE DESIGN: As user-friendly for lefties as it is for right-handed brushers, the ergonomic design helps reduce pressure on teeth and gums for optimal oral health.
