Toothbrush
Natural bristle brushes were invented by the ancient Chinese who made toothbrushes with bristles from the necks of cold climate pigs.
French dentists were the first Europeans to promote the use of
toothbrushes in the seventeenth and early eighteenth centuries. William
Addis of Clerkenwald, England, created the first mass-produced
toothbrush. The first American to patent a toothbrush was H. N.
Wadsworth and many American Companies began to mass-produce toothbrushes
after 1885. The Pro-phy-lac-tic brush made by the Florence
Manufacturing Company of Massachusetts is one example of an early
American made toothbrush. The Florence Manufacturing Company was also
the first to sell toothbrushes packaged in boxes. In 1938, DuPont
manufactured the first nylon bristle toothbrushes.
Hard to believe, but most Americans did not brush their teeth until Army
soldiers brought their enforced habits of tooth brushing back home
after World War II.
The first real electric toothbrush was produced in 1939, and developed
in Switzerland. In 1960, Squibb marketed the first American electrical
toothbrush in the United States called the Broxodent. General Electric
introduced a rechargeable cordless toothbrush in 1961. Introduced in
1987, Interplak was the first rotary action electrical toothbrush for
home use.
