There are many different ideas about when and where the first toothbrush was invented. Some say it was invented in China around the 11th century. Others say the Romans(罗马人) invented it around the time of Caesar. Nobody knows the exact history of teeth cleaning.
Before the first toothbrushes, sharp(尖的) objects were used to clean teeth.
It’s believed that tribes(部落) in Africa and Australia invented the idea of cleaning their teeth. The modem toothbrush with bristles(毛) was invented in China much later in the 16th or 17th century. Toothbrushes moved to Europe in the mid 1600’s and then became widely used in the area.Animal hair was the first type of bristle to be used.
Today, toothbrushes have nylon(尼龙) bristles and normally have a plastic handle. Animal hair was replaced by nylon in 1938. Electric toothbrushes were invented and marketed in 1880 by “Dr Scott”. The popularity of the electric toothbrush did not take off until after World War Ⅱ. When the cordless(无线的) model was invented in 1960, its popularity increased a lot.
