The first toothbrushes were used where made from small sticks or twigs which where mashed at one end to create a broader cleaning surface. The Chinese lay claim to the first bristle toothbrush. In the 17th century Europe adopted the bristle brush. The first electric toothbrush was marketed in 1880, though the Swiss developed the first effective electric toothbrush just after World War II. It was introduced in the United States around 1960. A year later, the first cordless model was developed and proved to be popular with both consumers and dentists.
