The dental drill has been around since 7,000 BC.. It was the bow drill and while it worked, it did not work quickly. Imagine that dentist having you in a chair and drilling on your tooth, which already hurts, and taking maybe an hour to get to the source of the problem. (Or maybe longer) In 1864 British dentist George Fellows Harrington created “Erado” which was a better drill but still only operated around 15rpm. That may not mean anything to you until you realize that in 1914 that drill went from 15rpm to 3,000 rpm. Just a bit faster. The next step up was to 180,000 rpm and those used today run at some 800,000 rpm.
How to celebrate – Thank your dentist for the faster speeds of drills. Imagine, if you can, having a dentist work on you with a drill that ran 15rpm. Take care of your teeth so you don’t have to visit the dentist’s drill.
