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 about 3,000 microplastic particles every single brush. 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 Emits More EMF Than A Microwave
Every electric toothbrush runs a motor, and that motor emits electromagnetic radiation. Measured at the handle, many popular brushes read higher than standing in front of a running microwave. The difference is you do not hold a microwave against your jaw for four minutes a day, inches from your brain, every day for years.
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.

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.
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, 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 horse bristle, natural keratin from top to bottom, with no plastic to shed.
