Who invented the first toothbrush?
The Ancient Chinese made toothbrushes with bristle picked from the neck hair of Siberian wild boars. Stick like toothbrushes have also been found in the pyramids of ancient Egypt. French dentist were the first Europeans to promote the use of toothbrushes in 17th century.
William Addis of Clerkenwald, England, created the first mass-produced toothbrush.
The first patent for a toothbrush was granted to H. N. Wadsworth in 1857 in the United States, but mass production in the United States only started in 1885. In the United States, brushing teeth did not become routine until after World War II, when American soldiers had to clean their teeth daily.
During the 1900s, celluloid handles gradually replaced bone handles in toothbrushes. Natural bristles were the only source of bristles until Du Pont invented nylon. Natural animal bristles were replaced by synthetic fibers, usually nylon, by DuPont in 1938. The first nylon bristle toothbrush, made with nylon yarn, went on sale on February 24, 1938. The first electric toothbrush, the Broxodent, was invented in Switzerland in 1954.
