Look at the seam on the left. That black ring is what builds up where a plastic electric head meets the handle, in the gap you can't reach and never think to clean. The one on the right doesn't have it. Every plastic snap-on head has that joint, and it stays wet. Water and toothpaste work into the seam, sit in the dark, and grow exactly what you're seeing. You rinse the bristles after every brush and never touch the one spot that actually collects the gunk, because you can't get to it. Here's the mechanism: the standard head is molded hollow and clicks onto the handle, leaving a wet cavity and a wet seam that trap moisture in the dark. That's where mold and bacteria build. The PRIMALS bamboo head is built without that hollow moisture cavity, so there's no dark wet pocket for it to collect in, and no nylon shedding plastic into your mouth on top of it. You've probably pulled a head off before and seen something you didn't like in that gap. Most people wipe it and keep going, because the alternative is buying another one just like it. Every replacement had the same seam and did the same thing. This one doesn't. The PRIMALS Electric Toothbrush, the first natural bristle electric toothbrush: ✅ Bamboo head built without the hollow moisture cavity that standard heads trap mold in ✅ Real natural bristles, a keratin fiber with no plastic to shed ✅ Sonic power that removes 10x more plaque than a manual brush (plaque removal compared to manual brushing) ✅ Low-EMF engineered, 5x l
