A sonic toothbrush is usually two synthetic things: a nylon head and a motor running against your jaw. This one is neither. The bristles are real boar hair on a bamboo head. And we put the motor on a meter, at the same distance and mode as the leading sonic brush. Theirs read 265 V/m of electric field. This one read 14. That's 19 times less. Here's the mechanism: distance. Field strength falls off sharply the further you get from the source, which is why a microwave across the kitchen isn't the concern. A toothbrush is the opposite case, sitting against your jaw for two minutes, twice a day, for years. Prolonged exposure has been linked to poor sleep, reduced focus, and neurological stress. The bristle is the other half. Nylon is extruded, so every filament comes out smooth, blunt and identical, and once it's worn it skims over buildup instead of gripping it. At 30,000+ strokes per minute friction shears fragments off those tips, 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 upgrading within the category fixes neither half. A newer handle. The deep clean head, still nylon. Replacing heads early, which restarts fresh plastic at full rate. 5,000+ clinicians across the US share PRIMALS with their patients. ✅ Natural firm boar bristle on a glue-free bamboo head, textured so it grips plaque instead of skimming over it ✅ Low-EMF engineered motor, reading 14 V/m against the leading sonic brush's 265 on the same meter ✅ Sheds no plastic, because there are no nylon bristles in it ✅ Naturally antimicrobial, with none of the stale smell nylon heads develop ✅ 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 🎁 Every Bundle Includes: 🤝 FREE gifts with every bundle 🤝 2 FREE boar bristle and bamboo heads in the box 🤝 FREE next day shipping, shipped from our California warehouse 🤝 Satisfaction guaranteed on every order Demand is running ahead of stock, so check the current ship date at checkout. 100,000+ people have made the switch, including Oral-B and Sonicare owners who compared the clean directly.
