8 things people love about the PRIMALS Boar Bristle Electric Toothbrush
You bought an electric toothbrush for a deeper clean. Nobody mentioned the head is plastic, and that a sonic motor grinds nylon into your gums twice a day. Here's what switching to real boar bristle actually fixes.
01You stop ingesting 2.3 million microplastics a year
That's what a nylon head sheds into your mouth, around 3,000 particles every use, and a sonic motor grinds them loose even faster.
PRIMALS is real boar bristle woven into bamboo. No nylon anywhere, so there is nothing to shed.
02It isn't castor oil nylon in disguise
The eco alternative is nylon-11. Castor oil instead of petroleum, but still a plastic filament, so it still frays and sheds under a sonic motor.
PRIMALS bristle is keratin, the same protein as hair. Not nylon-6, not nylon-11, not plastic of any grade.
03It closes a gap you can actually control
Microplastics have turned up in human arteries, brain tissue, even breast milk. A 2024 study tied them to a 4.5x higher risk of heart attack and stroke.
Most sources are impossible to avoid. This one takes a single swap, and then it is gone from your routine for good.

04The motor reads 19x lower on the meter
Every electric brush runs a motor inches from your brain. So we put them all on the same meter and measured.
265 V/m for the leading sonic brush. 14 V/m for PRIMALS. Roughly 19x less electric field, 5x less magnetic.
Magnetic field: 88.29 µT vs 17.62 µT. Same ERICKHILL RT-100 meter, 100+ readings averaged at the highest intensity, same distance and mode. Individual readings may vary.
05The head doesn't grow mold on your sink
A plastic head traps moisture and grows mold and bacteria deep inside, exactly where you can't clean, then drives all of it against your gums.
Our bamboo head is heat-carbonized and antimicrobial. It dries out between brushes instead of quietly festering.
06It still hits 62,000 VPM
Going natural isn't a downgrade here. It removes 10x more plaque than manual brushing, with 5 modes, 3 intensities and a smart 2-minute timer.
It's also IPX7 waterproof, and one charge lasts up to 365 days. You plug it in about once a year.
07Boar bristle gives a scrub nylon can't
Boar is keratin, the same protein as hair, and it's the firm, dense bristle. It digs into the gumline and between teeth instead of skating over the surface.
Every bristle also ends in a natural taper. Nylon gets extruded and chopped, so its tip has to be polished round after the fact.
08Every head is hand-woven, never glued
Conventional heads staple nylon tufts into wells of synthetic glue. That glue sits inside the head soaking in water twice a day, right where you can't reach it.
PRIMALS heads are hand-woven into bamboo. Zero glue, zero adhesive, and no BPA, phthalates or PFAS.

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 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.
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.
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 boar heads to start, and replacements come in 4-packs. 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 boar 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.
