Accelerates The Shedding
They Found Out Their Electric Toothbrush Was Pulsing 2.3 Million Microplastics Into Their Body
Plastic toothbrushes shed 2.3 million microplastic particles a year, about 3,192 every brush. The electric motor grinds the nylon even faster, and your gums soak those particles straight into your bloodstream.

With The PRIMALS Electric Toothbrush
- 🌿Zero Microplastic SheddingReal horse bristles on a bamboo head. No nylon to grind into your gums.
- ⚡All The Power, None Of The PlasticYou keep the 62,000 VPM deep clean, minus the microplastics.
That Changes Nothing
They Found Out The "Castor Oil Alternative" Is Still Nylon (AKA Plastic)
Castor oil bristles are nylon-11. The feedstock started as a plant instead of petroleum, so it is a different grade of nylon, not a different material. It still frays, the motor still pulses EMF beside your brain, and the head is still hollow plastic.
With The PRIMALS Electric Toothbrush
- 🐴A Bristle That Was Never PlasticReal horse bristle is keratin, the same protein as hair. Not nylon-6, not nylon-11, not plastic of any grade.
- 🧠The Motor Was Solved TooLow-EMF engineered, so you are not swapping one exposure for a greener label on the same one.
- 🌱Bamboo Head, Not A Plastic ShellHand-woven into heat-carbonized bamboo, with no hollow cavity sitting wet on your sink.
Backed By Research
The Plastic In Your Mouth Is Ending Up In Your Heart and Brain
Those particles don't leave. They build up in your organs, and have been found in human arteries, brain tissue, and breast milk. A 2024 study linked microplastics in arteries to a 4.5x higher risk of heart attack, stroke, and death.
With The PRIMALS Electric Toothbrush
- 🚫No More MicroplasticsNo plastic bristles, so nothing sheds into your gums when you brush.
- ✅The Easiest Exposure to CutMost microplastic sources are hard to avoid. This one you can remove today.
No One Warned You About
They Discovered Their Electric Toothbrush Emits More EMF Than a Microwave
Electric toothbrush motors emit up to 370 milligauss of magnetic field, more than a microwave up close. That's pulsing right next to your brain twice a day, and it's one of the closest EMF exposures in your whole routine.
We put every brush on the same meter, at the same distance, and filmed it. PRIMALS read roughly 19x less electric field and 5x less magnetic field than the leading sonic brush.
Magnetic field read 88.29 µT against 17.62 µT. Tested on the same ERICKHILL RT-100 meter. Figures are averaged across 100+ readings, all taken at the highest intensity setting, at the same distance and in the same mode. Individual readings may vary with meter, distance, mode, and intensity.
With The PRIMALS Electric Toothbrush
- 📡Low-EMF Engineered MotorBuilt to cut the magnetic field pulsing next to your brain.
- 🧠No Radiation Trade-OffA powerful electric clean without the daily EMF against your head.
Is a Mold Trap
Their Old Brush Head Was Quietly Growing Mold and Bacteria
A plastic head sits wet in your bathroom for weeks, and mold and bacteria breed inside it where you can't see or clean. Then the motor pushes all of that against your gums twice a day, right into your mouth.
With The PRIMALS Electric Toothbrush
- 🔥Heat-Carbonized Bamboo HeadThe bamboo head is heat-carbonized and sterilized, so it doesn't grow mold like plastic.
- 💧Dries Clean, Stays AntimicrobialBamboo sheds moisture and resists the bacteria a wet plastic head traps.
Gentle On Your Gums
Soft On Your Gums, So You Stop Brushing Away Your Gumline
Stiff bristles scrape at a fixed angle and are a leading cause of gum recession and enamel wear, and once your gumline recedes it doesn't grow back. Horse bristle is the softest natural bristle there is, so it flexes and cleans gently along the gumline instead of scraping it raw. A thorough clean that's kind to sensitive gums.
With The PRIMALS Electric Toothbrush
- 🪶Softest Natural BristleThe gentlest option for sensitive gums, receding gumlines, and anyone who brushes too hard.
- 🛡️Protects Your GumlineFlexes instead of scraping, so you clean without wearing your gums and enamel down.
- 🔋365-Day Battery, WaterproofCharge once, brush for a year. IPX7 for the shower.

Why PRIMALS Beats The Plastic Electric
Questions? We Have Answers.
Two things. The nylon heads shed microplastics, and the sonic motor speeds that up. And the motor emits EMF, up to 370 milligauss, right next to your head twice a day. You wanted a better clean, not plastic and radiation.
Not really. Castor oil bristles are nylon-11, a plastic filament made from a plant feedstock instead of petroleum. The source changed, the material didn't. It still frays and sheds into your mouth, and a sonic motor speeds that up the same way. If the goal is no plastic in your mouth, the bristle has to be a natural fiber, not a plant-based plastic.
Yes. Horse bristle is the softest natural bristle available, so it flexes gently along the gumline instead of scraping like stiff nylon. It's ideal for sensitive gums and receding gumlines. Want a firmer scrub? Swap in our boar bristle heads on the same handle.
Yes. Our replacement heads fit all Philips Sonicare click-on handles, including Protective Clean, Expert Clean, Diamond Clean, 9900 Prestige, Healthy White, and Flex Care. If your current head clicks on without twisting, it fits. PRIMALS is not affiliated with or endorsed by Philips. Compatibility is based on handle design only.
Up to 365 days on a single charge, depending on use, with wireless charging on the included dock. The brush is also IPX7 waterproof, so you can use it in the shower and rinse it under running water with no worry.
Every 1 to 3 months, or sooner if the bristles fray. It comes with 2 horse heads to start, and replacements come in 4-packs in horse or boar. Subscribe so you never run out.
Look at the bristles. The vast majority still use nylon. Since the bristle is the only part that contacts your mouth, those heads still shed microplastics. PRIMALS uses a bamboo base plus actual horse bristle, fully natural top to bottom.
Orders ship quickly with tracking, and every unit comes with a 2-year warranty and same-day human email support. If anything is ever off, we make it right.
