There's no filter on your toothbrush

You've built filters into your life. One on the tap. One on the shower. Labels checked at the shop. Every one of them sits between you and something you'd rather not absorb. There's no filter on your toothbrush, and it's the most direct route in. A plastic toothbrush releases up to 2.3 million microplastic particles a year, roughly 3,192 every single time you brush (ScienceDirect, 2025). Here's the mechanism: no barrier and high permeability. Swallowed plastic passes through a digestive system built to sort what enters. Nylon fragments from a bristle skip all of that. They're pressed directly into gum tissue, which is 10x more permeable than skin, under pressure, twice a day. That's absorption straight into the bloodstream, and 89% of blood samples now test positive for microplastics. Which is why the swaps that look right don't help. The bamboo-handle brush still has nylon glued into a plastic head. The extra soft one is the same petroleum drawn thinner. Replacing it early just restarts fresh nylon at full shedding rate.
