Plastic toothbrushes shed microplastics into your mouth twice daily. Oral tissue is highly absorptive. While exposure per use is small, the cumulative daily effect over years is significant.

Chemical & Health Analysis
Polypropylene / ABS (toothbrush handles)
Plastic toothbrushes shed microplastics into the mouth during brushing. Oral mucosa is highly absorptive — microplastics and chemical additives can enter the bloodstream directly through oral tissue.
Nylon-6 bristles
Conventional nylon bristles shed nanoparticles with each use. A 2021 study found measurable nylon particles in saliva after brushing with conventional toothbrushes.
