PRIMALS Horse Bristle Electric Toothbrush

Mainstream electric toothbrushes use nylon bristle heads made from petroleum-derived plastic. Every time you brush, those nylon bristles shed microplastic particles directly into your mouth. A 2025 PubMed-backed study confirmed that plastic toothbrushes release up to 2.3 million microplastic particles per year. With an electric toothbrush vibrating at 30,000+ strokes per minute, that shedding is accelerated.

On top of that, conventional electric toothbrushes emit EMFs (electromagnetic fields) right next to your brain twice a day. Studies show levels can reach 70 to 90 microtesla near the head, and long-term exposure has been linked to poor sleep, reduced focus, and neurological stress.

The replacement heads are also full of BPA, phthalates, and PFAS that leach into your mouth with every use. And if you have sensitive gums, stiff nylon bristles make it worse. They scrape against your gumline at 30,000+ strokes per minute instead of flexing with it. You wanted a gentler clean, not a daily dose of toxins and irritation.

It's the world's first natural-bristle sonic toothbrush, now with the softest natural bristle available for electric toothbrushes. Instead of plastic nylon heads, we use:

• 100% Pure Horse Bristles on a Bamboo Head
• The Softest, Finest Natural Bristle Available
• Low-EMF Engineered Motor
• Zero Plastic Bristles, Zero Microplastics
• Zero Toxic Glue
• Free from BPA, Phthalates & PFAS
• Korean LG PC Plastic Handle (BPA-free) with Pearl 8-Layer Spray Baking Finish

Horse bristles are finer and more flexible than boar. They flex with your gums instead of scraping against them, so you get 62,000 VPM sonic cleaning power that's as gentle as it is powerful, without any of the toxic exposure that comes with mainstream electric toothbrushes.

Yes. The PRIMALS Electric Toothbrush is designed with interchangeable heads. Horse bristle heads are the softest natural bristle available, perfect for sensitive gums, receding gumlines, and anyone who prefers a gentler brushing experience. Boar bristle heads are firmer and denser for a deep, powerful scrub, ideal if you want maximum plaque removal without sensitive gum concerns. Both are 100% natural, plastic-free bristles, and fit the same handle. Simply swap the head in seconds.

For optimal hygiene and cleaning performance, we recommend replacing your brush head every 1 to 3 months. Because PRIMALS heads are made from 100% natural horse or boar bristles woven into a bamboo base, they wear differently than synthetic nylon, so it helps to watch the bristles themselves rather than just the calendar.

Replace your brush head sooner if you notice any of the following:

• Frayed, bent, or splayed bristles. Once bristles lose their shape, they can't reach between teeth or along the gumline effectively.
• Loss of softness or flex. Horse bristles should stay fine, soft, and flexible. When they start to feel limp, matted, or flattened, cleaning power drops.
• Reduced cleaning effectiveness. If your teeth don't feel as smooth and clean after brushing, the bristles are likely worn down.
• Bristle loss or split bundles. Some minor shedding is normal in the first 1 to 2 weeks as the bamboo adjusts to humidity, but ongoing bristle loss or split bundles mean it's time for a fresh head.
• After illness. Replace your head after a cold, flu, or any infection to avoid reintroducing bacteria into your mouth.

Tip: Stand your brush head upright to air dry between uses and rinse thoroughly after brushing. Proper drying keeps the natural bristles in better condition for longer.

Your toothbrush comes with 2 horse bristle heads to get you started. Replacement heads are available in 4-packs in both horse and boar bristle options.

• In your first few uses, a small number of bristles may naturally shed as the bamboo adjusts to your local humidity. This is completely normal and stops after 1 to 2 weeks.
• Stand the toothbrush upright on the charging dock after each use for optimal drying.
• Rinse the bristles under warm water before use for the smoothest feel.
• Leave a 0.5 to 1mm gap between the brush head and handle for proper vibration transfer.
• Replace your brush head every 1 to 3 months for optimal hygiene.
• If bristles flatten quickly, you may be brushing with too much force. With horse bristles you barely need any pressure at all, let the sonic vibration do the work.
