Prior to the dental drill, teeth were often extracted using picks and scissors. The first patented foot drill was introduced in 1790 by George Washingtons dentist John Greenwood (1760-1819). Improvements were made throughout the 19th century to increase their speed and accuracy. Significant success came with the creation of the first electric-powered drill in 1875, although they were not widely used until electricity was more readily available in the 1910s.
