A patent print poster of a Toothbrush invented by F. E. Wolcott. The patent was issued by the United States Patent Office on November 18, 1941. 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 animal bristles were also replaced by synthetic fibers, usually nylon, by DuPont in 1938. The first nylon bristle toothbrush, made with nylon yarn, went on sale in 1938.
