Plastic was invented to be cheap and endless. It spread into packaging, into kitchen utensils, and eventually into toothbrush bristles. Nylon became the standard in 1938, and not because it cleaned better. Because it was cheaper to mass-produce. Nothing about the bristle has changed since. Here's the mechanism: nylon is extruded petroleum filament, and friction shears fragments off the tips with every stroke. An estimated 3,192 microplastic particles per use, up to 2.3 million a year (ScienceDirect, 2025). Gum tissue is 10x more permeable than skin, so unlike plastic in food or water, these skip digestion entirely and absorb directly. On an electric it happens faster, because 30,000+ strokes per minute degrades the bristle quicker than a hand could. I couldn't accept that as the only option. So we built the world's first natural-bristle electric toothbrush. Soft horse bristle, chosen because it's the gentlest bristle there is and because a stiff bristle at 30,000 strokes a minute scrapes the gumline instead of flexing with it. Hand-woven into the head, so there's no glue in the part that goes in your mouth. Nothing in it that can shed. And in our own meter testing, roughly 19 times less electric field than the leading sonic brush at matched distance and mode. 5,000+ clinicians across the US share PRIMALS with their patients. ✅ Real horse bristle, the softest natural bristle available for electric brushes ✅ Hand-woven into the head, so there's no glue anywhere in it ✅ Sheds no plastic, because there are no nylon bristles in it ✅ Low-EMF engineered, 19x less electric field than the leading sonic brush in our own meter testing ✅ Made for sensitive gums, receding gumlines, and delicate enamel ✅ 62,000 VPM sonic cleaning, removing 10x more plaque than a manual brush ✅ 365-day battery on one wireless charge, 5 modes, 3 intensity levels, IPX7 waterproof, 2-year warranty 🎁 Every Bundle Includes: 🤝 FREE gifts with every bundle 🤝 2 FREE horse bristle and bamboo heads in the box 🤝 Wireless charging stand and charger included 🤝 FREE next day shipping, shipped from our California warehouse 🤝 Satisfaction guaranteed on every order 100,000+ people have made the switch across the range.

This is shedding into your mouth every night and you'd never notice. The materials in a conventional brush head were chosen because they're cheap to produce. Nylon replaced natural bristle in 1938 for exactly that reason, and nothing has changed since. Here's the mechanism: nylon is extruded petroleum filament, built to hold its shape. At 30,000+ strokes per minute a bristle engineered not to bend doesn't flex at the gum margin, it scrapes. And friction shears fragments off the tips while it does, roughly 3,192 microplastic particles per use, up to 2.3 million a year (ScienceDirect, 2025), into gum tissue 10x more permeable than skin. So I switched. Five modes, three speeds, and a head made of bamboo and real horse bristle, which is the softest natural bristle there is. It bends with your gums instead of scraping, and there's nothing in it to shed. Two replacement heads come in the box, and they click on and off in a second. There's a wireless charging stand, and a charger you'll barely use because the battery runs 365 days on one charge. 5,000+ clinicians across the US share PRIMALS with their patients. ✅ Real horse bristle, the softest natural bristle available for electric brushes ✅ Made for sensitive gums, receding gumlines, and delicate enamel ✅ Sheds no plastic, because there are no nylon bristles in it ✅ 5 modes and 3 intensity levels, adjustable mid-brush ✅ 2 replacement heads in the box, clicking on and off in a second ✅ Wireless charging stand included, 365-day battery on a single charge ✅ 62,000 VPM sonic cleaning, low-EMF engineered, IPX7 waterproof, 2-year warranty 🎁 Every Bundle Includes: 🤝 FREE gifts with every bundle 🤝 2 FREE horse bristle and bamboo heads in the box 🤝 Wireless charging stand and charger included 🤝 FREE next day shipping, shipped from our California warehouse 🤝 Satisfaction guaranteed on every order 100,000+ people have made the switch, including people who assumed every electric was too harsh for them. Cheap to make was never the same as good for your gums. Click "Shop now" and see what's included.

Not one, not two, not three, not four. Five modes in one electric toothbrush. Clean, White, Gum Care, Massage and Tongue, plus three intensity levels. And the heads are bamboo with real horse bristle, so you're not putting plastic in your mouth every night. Here's the mechanism: every conventional head is nylon, and the motor accelerates it. At 30,000+ strokes per minute friction shears fragments off the tips faster than it would by hand, roughly 3,192 microplastic particles per use, up to 2.3 million a year (ScienceDirect, 2025). Gum tissue is 10x more permeable than skin, so unlike plastic in food or water, these skip digestion entirely and absorb straight into the bloodstream. There's no nylon in this one at all. Horse hair is also the softest natural bristle there is, so it bends with your gums rather than scraping at speed. The battery runs 365 days on a single charge, there's a charging station the handle sits straight onto, and two replacement heads come in the box. 5,000+ clinicians across the US share PRIMALS with their patients. ✅ 5 modes and 3 intensity levels, adjustable mid-brush ✅ Real horse bristle, the softest natural bristle available for electric brushes ✅ Sheds no plastic, because there are no nylon bristles in it ✅ Made for sensitive gums, receding gumlines, and delicate enamel ✅ 2 replacement heads in the box, clicking on and off in a second ✅ Charging station included, 365-day battery on a single charge ✅ 62,000 VPM sonic cleaning, low-EMF engineered, IPX7 waterproof, 2-year warranty 🎁 Every Bundle Includes: 🤝 FREE gifts with every bundle 🤝 2 FREE horse bristle and bamboo heads in the box 🤝 Charging station and charger included 🤝 FREE next day shipping, shipped from our California warehouse 🤝 Satisfaction guaranteed on every order 100,000+ people have made the switch, including people who assumed every electric was too harsh for them.
