Your Sonicare bristle head fires 31,000 strokes a minute. That power drives 2.3 million microplastic particles off the plastic head and into your body every year. See why Sonicare users just swap the head for natural boar bristle.

Your Sonicare handle is the expensive, durable part, and it is fine. The only thing worth changing is the plastic head that clicks onto it. A 2025 study found that plastic bristle heads release over 3,000 microplastic particles into your mouth every single time you brush, and your Sonicare's 31,000 strokes a minute only speed that up. That's 2.3 million plastic fragments a year, absorbing through your gums into your bloodstream twice a day. Smart Sonicare users have caught on. They keep the handle and ditch the plastic head for natural boar bristle that doesn't shed.
With PRIMALS Boar Bristle Replacement Heads:
Zero Microplastics Ingested
Natural boar bristles don't fray or fragment, so no plastic particles enter your bloodstream when you brush.
Ends 2.3 Million Particles Per Year
A 2025 peer-reviewed study proves plastic heads release 3,000+ particles every use. Boar bristle releases zero.
Keeps Your Sonicare Power
You lose the plastic, not the deep sonic clean. Same handle, same power, natural head.
Nylon bristle heads aren't just plastic, they're chemical carriers. Made from crude oil, they can contain BPA, phthalates, and PFAS that leach into your mouth and absorb through your gum tissue into your bloodstream. These are known endocrine disruptors that throw off hormonal balance, damage your gut microbiome, and trigger chronic inflammation. Swapping to a boar bristle head means zero synthetic toxins entering your system every time you brush.
With PRIMALS Boar Bristle Replacement Heads:
Protects Your Hormones
No BPA, phthalates, or PFAS absorbing into your bloodstream twice a day and disrupting your endocrine system.
Supports Gut Health
Stop flooding your system with plastic particles that damage your microbiome and cause bloating and inflammation.
Lowers Your Toxic Load
Every brush with PRIMALS is one less source of crude-oil chemicals your body has to detox.
People are sick of choosing between a clean mouth and not getting poisoned. Soft nylon bristles flex on contact instead of scrubbing, leaving plaque behind while still shedding microplastics into your mouth. PRIMALS boar bristles are firmer and more effective, they dig in and remove buildup, leaving your teeth polished and squeaky clean. Better cleaning power on the Sonicare handle you already own, zero toxic trade-offs.
With PRIMALS Boar Bristle Replacement Heads:
Removes Plaque Effectively
Firm boar bristles scrub away the plaque and stains that soft plastic bristles leave behind.
Polished, Squeaky Clean Feel
No more bendy nylon that flexes on contact. Boar bristles deliver the deep clean your teeth actually need.
Elite Durability
Plastic bristles fray and splay within weeks while shedding even more microplastics. Boar bristles hold their shape far longer.
The plastic head you click on is hollow, and it sits wet in your bathroom for weeks. Mold and bacteria breed inside that housing where you can't see or clean, then you press the head back against your gums twice a day. PRIMALS heads are solid heat-carbonized bamboo that resists mold, and they dry clean between uses.
With PRIMALS Boar Bristle Replacement Heads:
Heat-Carbonized Bamboo Head
The bamboo head is heat-treated, so it resists mold instead of trapping it inside like a hollow plastic head does.
Dries Clean, Stays Antimicrobial
The natural bristle and bamboo head shed moisture and resist bacteria between brushes.
No Hidden Housing To Grow Mold
Unlike a hollow plastic head, there's no sealed cavity for mold and bacteria to breed in.
