PRIMALS Boar 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. You wanted a better clean, not a daily dose of toxins.

It's the world's first natural-bristle sonic toothbrush. Instead of plastic nylon heads, we use:

• 100% Pure Boar Bristles on a Bamboo Head

Yes. The PRIMALS Electric Toothbrush is designed with interchangeable heads. Boar bristle heads are firm for a deep, powerful clean. Horse bristle heads are softer and gentler, perfect for sensitive gums, receding gumlines, or anyone who prefers a softer brushing experience. Both are 100% natural, plastic-free, 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 boar or horse 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 firmness or flex. Boar bristles should stay firm and dense for a deep clean. Horse bristles should stay soft and flexible. When either starts to feel limp 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 boar bristle heads to get you started. Replacement heads are available in 4-packs in both boar and horse 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.
• Run the bristles under warm water before use to soften them slightly.
• 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. Use lighter pressure and circular motions.
