6 Reasons Smart People Are Ditching Their Plastic Electric Toothbrushes
The brush you use twice a day is shedding plastic into your bloodstream and pulsing EMF beside your brain. Nobody told you any of this.
See What People Switched To
Are Plastic
Their Brush Was Shedding 2.3 Million Microplastics Into Their Body Every Year
Nylon is plastic. Every plastic electric head is nylon on a plastic core, and a 2025 study found those bristles release 3,000+ microplastic particles per use. That is 2.3 million a year, and the sonic motor only speeds it up. Your gums are one of the most absorbent surfaces in your body, so those particles go straight into your bloodstream twice a day. (PMID:40680448)
What That Actually Means
- 🩸Straight Into Your BloodstreamGum tissue absorbs fast. There is no filter between your mouth and your circulation.
- 📈It Adds Up Every Single DayTwo brushes a day, every day, for years. The exposure never stops and never resets.
That Changes Nothing
The Castor Oil Alternative They Bought Was Still Nylon
This is where most people think they have solved it. 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 under a sonic motor. And the bristle was only ever half of it: the same motor sits beside your jaw, and the head is the same hollow plastic.
What That Actually Means
- 🏷️A Greener Label, The Same MaterialPlant-derived plastic is still plastic. Nylon-11 behaves like nylon-6 in your mouth.
- 🔄Nothing Else Changed EitherSame class of motor, same hollow head, same chemicals in the housing.
Backed By Research
Those Particles Don't Leave. They End Up In Your Heart And Brain
Microplastics do not pass through. They build up. Researchers have now found them in human arteries, brain tissue, and breast milk. A 2024 study linked microplastics in arterial plaque to a 4.5x higher risk of heart attack, stroke, and death, and brain tissue has been found to hold more of them than almost any other organ.
What That Actually Means
- 🫀They Accumulate, They Don't ClearWhat goes in mostly stays in, building up in tissue year after year.
- 💔Linked To Serious OutcomesArterial microplastics are associated with sharply higher cardiovascular risk.
No One Warned You About
The Motor Pulsing Beside Their Skull Runs An EMF Field Twice A Day
Every electric toothbrush runs a motor, and that motor emits an electromagnetic field. You hold it against your jaw for four minutes a day, inches from your brain, every day for years, one of the closest EMF exposures in your whole routine. Nobody publishes what theirs gives off, so we measured ours.
We put every brush on the same meter, at the same distance, and filmed it. PRIMALS read roughly 30x less electric field and 11x less magnetic field than the leading plastic sonic brush.
Both brushes tested on the same ERICKHILL RT-100 meter, averaged across 100+ readings at the highest intensity, same distance and mode. On the magnetic side, the leading plastic brush reads close to the international public-exposure reference level (ICNIRP, 100 µT) while PRIMALS reads a small fraction of it. Individual readings may vary with meter, distance, mode, and intensity.
What That Actually Means
- 🧠Inches From Your BrainContact exposure at the jaw is nothing like standing across the kitchen.
- ⏰Twice A Day, Every DayShort sessions, but relentless repetition over years of use.
Is A Mold Trap
Inside That Hollow Plastic Head, Mold And Bacteria Were Growing
The head you click on is a sealed plastic cavity that sits wet in a humid bathroom for weeks. Mold and bacteria breed inside it where you cannot see or clean, then you press it against your gums twice a day. And the plastic itself is petroleum-derived, so it can carry BPA, phthalates, and PFAS, known endocrine disruptors that leach into your mouth and absorb through your gum tissue.
What That Actually Means
- 🦠You Cannot Clean What You Cannot ReachThe hollow housing traps moisture and grows what it grows.
- 🧬Hormone Disruptors In Your MouthBPA, phthalates, and PFAS are linked to endocrine and gut disruption.
For This Instead
So They Switched To The One Electric Brush Without Any Of It
You do not have to give up the deep sonic clean to get away from the plastic. The PRIMALS Boar Bristle Electric Toothbrush is the first natural bristle electric toothbrush, built to solve every problem above at once. Real boar bristle on a bamboo head, so there is nothing to shed. Low-EMF engineering, so there is far less field beside your brain. Heat-carbonized bamboo, so it dries instead of molding. And 62,000 vibrations per minute, so you keep the clean you actually switched to electric for.
What Changes When You Switch
- 🌿Zero Microplastic SheddingReal boar bristle on bamboo. No nylon means nothing to grind into your gums.
- 🐗Keratin, Not Any Grade Of NylonThe same protein as hair. Not nylon-6, not nylon-11, not plastic of any kind.
- 🧠Low-EMF EngineeredFar less field pulsing next to your brain twice a day.
- 🔥Heat-Carbonized BambooDries between brushes instead of trapping moisture in a hollow plastic shell.
- ⚡62,000 VPM Sonic PowerAll the deep clean you switched to electric for, none of the plastic.
- 🧬No BPA, Phthalates Or PFASNo toxic glue and no forever chemicals leaching into your mouth.
The World's First Natural-Bristle Sonic Toothbrush
Every plastic head means more microplastics in your gums and more EMF by your brain. Keep the power. Drop the plastic.

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 right next to your head twice a day. You wanted a better clean, not plastic and EMF.
Boar bristle is firm, but it isn't harsh like plastic. It's naturally tapered, so it flexes and spreads pressure instead of scraping like stiff nylon. Want softer? Swap in our horse bristle heads, the softest natural bristle for electric.
Yes. Our replacement heads fit most click-on handles. If your current head clicks on without twisting, it fits.
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 boar heads to start, and replacements come in 4-packs in boar or horse. Subscribe so you never run out.
Look at the bristles. The vast majority still use nylon, and the "castor oil" ones are castor oil converted into bio-based nylon, chemically still plastic, so they still shed microplastics under a sonic motor. Since the bristle is the only part that contacts your mouth, a bamboo handle changes nothing. PRIMALS uses a bamboo base plus actual boar bristle, natural keratin from top to bottom, with no plastic to shed.
