Elevate your oral care routine with autobrush®'s Double-sided Nylon Brush Head with GumDefend™ Bristles. Featuring 58,000 ultra-soft, 45° angled bristles, our patented brush heads follow the ADA-approved BASS technique for superior plaque removal—27x more effective than traditional toothbrushes. GumDefend™ Bristles includes a fourth row of silicone bristles that stimulate the gums, increase blood circulation, and promote healthier tissues. Achieve a full-mouth clean in just 30 seconds. The improved brush head also includes blue bristles that fade with use, indicating when it's time to replace for peak performance. Compatible with any autobrush model, we recommend replacing brush heads every 30-60 days to prevent bacteria buildup and bristle wear.
