Product Description Introducing the "Premium Care Series" with a wide head that changes the conventional wisdom about toothbrushes. Experience an unparalleled brushing sensation that you'll notice after just one use. 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 your teeth, and the slim head allows the bristle tips to reach the often-missed back teeth. The ultra-fine bristles with a diameter of φ0.01 mm penetrate periodontal pockets to effectively remove plaque, while the flat bristles thoroughly eliminate surface plaque. This toothbrush features a double bristle design: soft bristles on the outside gently care for the gums, while hard bristles on the inside effectively clean the tooth surfaces and the gum line. With a high bristle density and a large contact area between the teeth and the brush, you can easily and efficiently remove plaque with your usual brushing. The wide head has a high number of bristle holes, totaling 48 holes. The regular head covers a large area with 7 rows of bristles. Bristle hardness is medium. Model number: B-8001M. Information tag number: 82. Material of bristles: saturated polyester resin. Main body
