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. The compact head allows for thorough cleaning of every corner. ■Bristle hardness: Medium ■Heat resistance: 60℃ *Color cannot be selected.
