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. Ref: About.com
The average toothbrush can contain 10 million bacteria or more—including E. coli and Staph, according to a study at the University of Manchester in England.
The Preferred Sonic Electric Toothbrush with a UV Sanitizer for the brush heads has a 7-minute timer control that effectively kills 99.9% of bacteria.
As Dr. Scott Frey said, UV sanitizers do work. They will reduce the bacterial count on your toothbrush. UV sterilization will cause mutations in the DNA of the microorganisms living on your toothbrush, and this will prevent them from reproducing, and they consequently die . https://www.quora.com/profile/Scott-Frey
