Ivory dentures and dentist's hand drill

This recording was created by attaching a contact microphone to some deaccessioned ivory dentures and then drilling into these, using a 200 year old dentist's hand drill. The drill is surprisingly sharp even after 200 years, and is one of the objects in the collection of the British Dental Association Museum. It is called a Finzi, after the inventor who originally designed it, and you can read about it here: http://www.nature.com/bdj/journal/v205/n6/covers/index.html #dentistry #healthcare #history #sonicwallpaper #teeth
