Laifen 6 Pack Adult Replacement Toothbrush Heads Compatible with Wave Electric (Solation, Gum Protection)

【Dynamic Balance & TÜV Certified】Features an integrated metal counterweight that stabilizes oscillation and significantly reduces handle vibration and noise. Crafted from premium, officially tested materials and TÜV-certified to ensure a safe, reliable, and premium brushing experience. 【Universal Compatibility】Specially engineered for the Laifen Wave series. These brush heads are 100% compatible with Wave, Wave Pro, and Wave Special models, perfectly supporting Laifen's innovative dual-action (oscillating and vibrating) brushing technology. 【Gentle Gum Protection & TPU Padding】Designed with a soft, recyclable TPU cushioned back that acts as a shock absorber. It effectively protects your teeth and gums from hard impacts, making high-frequency vibrations feel remarkably smooth and comfortable. 【Hygienic Copper-Free Bristle Anchoring】Utilizes advanced ultrasonic melting technology to secure the bristles without copper plates. This anchor-free design prevents corrosion, inhibits bacterial growth, and ensures a cleaner, safer, and longer-lasting oral hygiene routine. 【Premium Bristles with Fade Indicator】Equipped with high-quality DuPont or PBT bristles that clean deeply and efficiently between teeth. The built-in indicator bristles gradually fade after approximately 90 days, clearly reminding you when it’s time for an optimal replacement.
