@getprimals: A lot of "natural" wooden toothbrushes aren't quite as natural as the front of the box makes them look. The handle might be bamboo, beechwood, or another wood. The packaging might be compostable. The marketing might lean fully into sustainability and earthy aesthetics. But check the small print on the back, and one detail tends to repeat across almost every brand: nylon bristles. Nylon is a synthetic polymer derived from petroleum. A form of plastic. And the bristles are the part that actually touches your teeth and gums every single time you brush. A study published in Environmental Pollution analyzed toothbrush bristles, including those from eco-marketed brands, and found that they can shed microplastic particles during normal brushing. The gums absorb compounds faster than the digestive tract, which is part of why researchers are paying closer attention to oral care as a daily exposure source. A wooden handle doesn't fully solve the issue when the bristles are still synthetic. The PRIMALS Boar Bristle Toothbrush uses a sustainable bamboo handle paired with 100% real boar bristles. No nylon. No synthetic polymers. No petroleum-based bristles in your mouth. A truly natural brush.
