Every Plastic Toothbrush in Your House Sheds Microplastics Into a Mouth You Love
A 2025 study measured nylon bristles shedding 3,000+ particles per use, up to 2.3 million a year per person. Four brushes in one bathroom, four times the number.
- 🔬3,000+ particles per useMeasured on nylon toothbrushes. Twice a day, every day. (Ecotoxicology and Environmental Safety, 2025)
- 🏠Up to 9.2 million a year for a household of four2.3 million per brush, four brushes. That's the family number.
- 🩸Gum tissue absorbs, it doesn't rinseMore permeable than skin, so the particles don't simply wash away.
- ⚡Sonic motors wear nylon fasterTens of thousands of strokes a minute, working on plastic filament.
Every Electric Toothbrush Runs a Motor an Inch From Your Brain. Almost None Publish the Number.
EMF drops off with distance, and a toothbrush gets none. The leading electric toothbrush measured 300 V/m on our meter. PRIMALS measured 10.
- 📏Fields fall with distance, a toothbrush gets zeroYou keep the phone off your body. You can't keep a brush off your jaw.
- 📉30x less electric field, 11x less magnetic fieldSame meter, same mode, same distance, 100+ readings averaged.
- 🦷Fillings, crowns, or implants in the family?Researchers measured small currents induced in dental metal by electric toothbrush magnetic fields. (PubMed 23037851)
- 🤐No leading brand prints a readingBattery life is on the box. The EMF number isn't.
Readings are PRIMALS' own measurements on an ERICKHILL RT-100 meter, motor to motor, averaged across 100+ readings, and vary with meter, distance, mode, and intensity. For reference, the international public-exposure reference level is 100 µT (ICNIRP, a scientific body, not a government limit), and both brushes measured below it. Not a health claim.
Plastic Heads Are Molded Hollow. Water Sits Inside and Mold Grows Where You Can't Clean.
Every click-on plastic head has a cavity between head and shaft. It never fully dries, and the motor drives whatever grew overnight straight back into the mouth.
- 💧A cavity that holds water between brushesMolded hollow to save plastic. You can't rinse it, and you can't see it.
- 🌙Damp, dark, twelve hours at a timeExactly the conditions mold and bacteria need. (J Dent Hyg 88(4):237)
- 🔁The motor sends it backOn the next brush, it's driven into the mouth, including toward the throat.
- 🎋PRIMALS heads are solid bambooHeat-carbonized, no hollow chamber. It dries instead of breeding.
Castor Oil Bristles Are Still Nylon. Just Partly Made From Beans.
If you bought a castor oil brush to go plastic-free, the bristle never actually changed. Castor beans get turned into nylon-11, a synthetic filament in the same family as standard nylon.
- 🫘Castor oil is the feedstock, not the materialPlant-based describes where it came from, not what touches your gums.
- 🔬Still a plastic polymer, still shedsNylon-11 is a plastic filament, and plastic wears and sheds under a sonic motor.
- 💧Same hollow plastic head underneathSwap the bristle and the cavity that traps water is still there.
- 🐗Real boar bristle has no plastic to shedBoar bristle is a natural fiber. Nothing synthetic, nothing to break down.

Bought the four-pack after reading that nylon bristles shed microplastics into your gums. Two months in, everyone in the house is on boar bristle and nobody misses the old brushes. Cleans just as hard, nothing plastic in the mouth.
Tamsin Okonkwo-Reyes ✓ Verified buyerI ran my own EMF meter on our old sonic brush and nearly dropped it. The PRIMALS handle reads a fraction of that on the same setting. Same powered clean, way lower number, and the bamboo head is solid.
Bram Vandersloot ✓ Verified buyerSwitched the whole family to the boar bristle bundle. The firm bristle gets that deep-clean feel my old sonic never did, and it's a relief knowing there's no plastic or glue in it. The free tablets and scraper were a bonus.

Founded in Hawaii by a Woman Who Was Done Reading Labels
Lauryn started PRIMALS because every product she picked up turned out to be plastic, synthetic, or both, and the clean version didn't exist. It began with one boar bristle toothbrush. Now it's more than 20 products, and over a million people. The electric was built to the same standard: remove a toxin, don't add a feature.
