Pain Management
 |  | | The first toothbrush was invented in China in 1000 A.D. It was an ivory-handled toothbrush with bristles made from a horse's mane. Toothbrushes became popular in the 19th century among the Victorian affluent. Mass marketing and the advent of nylon bristles in the 20th century made toothbrushes inexpensive and available to everyone. |
