READ THE PASSAGE
Read about how toothbrushes have changed throughout history.
Toothbrushes Through the Ages
Archaeologists trace the use of tooth-cleaning tools back 5,000 years. In ancient Egypt and, later, 
in Greece, Rome, and the Middle East, people rubbed a frayed stick on their teeth to clean them. The first 
toothbrush was patented in China in 1498, although it may have been used there as early as the Tang 
Dynasty (618–907). They fastened stiff bristles from the back of boars’ necks to a handle made of bone or 
bamboo. One hundred years later, silver-handled toothbrushes found their way into the mouths of 
European nobility.
Still, most ordinary people in the seventeenth and eighteenth centuries cleaned their teeth with a rag, 
sometimes dipped in chalk or salt, sometimes attached to a stick to reach the back teeth. An Englishman 
named William Addis wanted to bring real toothbrushes to ordinary folk. In 1780, he created and marketed 
the first mass-produced toothbrushes, made of boar bristles attached to a bone handle. His business 
made him a wealthy man. In 1857, H. N. Wadsworth became the first American to patent a toothbrush.
Except for the development of plastic handles after World War I, toothbrushes did not change much 
until 1938, out of necessity. World War II disrupted the trade in Chinese boar bristles, and toothbrush 
makers looked for a replacement. The first modern toothbrush with nylon bristles was called Dr. West’s 
Miracle Toothbrush.
To date, there have been thousands of patents for toothbrushes worldwide. Today, brushes with 
angled handles, bristles of different lengths, electronic pulsing, rubber gum massagers, and tongue 
scrapers give people a wide array of options for keeping their pearly whites clean and healthy.
