Description Product Introduction The "Premium Care Series" with a wide head changes the common perception of toothbrushes. Once you use it, you will understand the exceptional brushing experience. The head is approximately 25% thinner than our conventional products, featuring a slim design that makes it easy to maneuver in the mouth. The densely packed bristles envelop the teeth, allowing the fine tips of the thin head to reach the often-ignored back teeth. The ultra-fine bristles with a diameter of φ0.01 mm penetrate periodontal pockets to remove plaque, while the flat bristles effectively eliminate surface plaque on the teeth. The outer bristles are soft to gently care for the gums, while the inner bristles are hard to thoroughly brush the tooth surfaces and the gum line, utilizing a double bristle design. With a high bristle density, the contact area between the teeth and the brush is wide, allowing for easy and efficient plaque removal during regular brushing. The wide head features many bristle holes, with a total of 48 holes, and a 6-row regular head for efficient brushing. Bristle hardness is medium. Model number: B-196. Information tag number: 62. Bristle material: saturated polyester resin. Main body material: polypropylene; rubber part
