摘要： Disclosed is a toothbrush having soft and hard bristles together. The toothbrush having soft and hard bristles with 6–10 mm in tapered length and 0.01–0.08 mm in diameter of end portions comprises: longer bristles(1) located at both edges; and shorter bristles(2) located at the central portion, wherein the bristles are generally in a semicircular form at their top portions when seen from a side, and a difference in length between the longer bristles(1) and the shorter bristles(2) is about 2–4 mm. The toothbrush can increase brushing efficiency and effectively remove foreign matters between teeth and inside periodontal pockets.
