Leading plastic vs leading castor oil vs PRIMALS

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.

Line up three brushes on a dark sheet and you can see the thing nobody prints on the box. Two of these are plastic. The white one is a standard plastic sonic brush. The green one markets itself as the natural, castor-oil alternative, but castor oil bristles are still plastic. The third is boar, a natural keratin fiber. Look at what surrounds each one. The plastic bristles leave debris. The natural one doesn't have any to leave. Here's the mechanism: a plastic toothbrush is nylon, and nylon is plastic. Published research on plastic toothbrushes puts it around 3,000 microplastic particles shed per use, roughly 2.3 million a year, and a sonic motor moving at 62,000 movements a minute only speeds the friction that breaks them loose. It happens right at the gumline, one of the most absorbent surfaces in your body. The castor-oil versions shed too, because the bristle itself never stopped being plastic. You can't see it in your bathroom because it's small and it goes down the drain. Put it on dark paper and it stops hiding.
