They even used feathers to pick their teeth after a good meal. Today, nearly everyone brushes their teeth with a toothbrush. The Chinese invented the toothbrush about 600 years ago. They used hairs from the Siberian wild pig to make the brush. Bamboo or bone was used for the handle. European travellers brought toothbrushes back from China. But they did not like the feel of the pig hairs. So they used horse or cow hairs instead. In modern times, most toothbrushes are made of nylon. But the purpose is the same: to keep your teeth clean. That way, you will grow up with strong, healthy teeth.

它们甚至在美餐一顿后用羽毛剔牙。今天，几乎每个人都用牙刷刷牙。 中国人大约在600年前发明了牙刷。他们用西伯利亚野猪的毛来制作刷子。把手是用竹子或骨头做的。 欧洲游客从中国带回了牙刷。但是他们不喜欢猪毛的触感。所以他们用马毛或牛毛代替。 在现代，大多数牙刷是尼龙做的。但目的都是一样的:保持牙齿清洁。这样，你长大后就会有强壮健康的牙齿。
