The "ultra-fine spiral edge bristles," made by twisting hexagonal bristles, trap plaque with their spiral edges. The ultra-fine bristles reach into hard-to-reach periodontal pockets to scrape out plaque, while the flat bristles thoroughly remove plaque from the tooth surface. The slim head reaches deep into the molars. A compact head that allows for thorough cleaning of every corner. ■Bristle hardness: Soft ■Heat resistance: 60℃ *Color cannot be selected.
