Dental instruments are the tools that dental professionals use to provide dental treatment. They include tools to examine, manipulate, restore and remove teeth and surrounding oral structures.
Dental tools have been used since the earliest days of human civilization. As long ago as 7000 BCE in the Indus Valley, which included present-day Pakistan, craftsmen treated tooth-related problems with a bow drill normally used for making fire or woodworking.
