A lump of beeswax was discovered in a 6,500 year old human jawbone. This may be the earliest evidence of a dental filling. The tooth may have had a crack and the beeswax was inserted to relieve the pain. It is not clear whether the wax was inserted by the person afflicted or by an early dentist. The jawbone was discovered in 1911 inside a rock in a cave in Slovenia. But with new radiocarbon analysis, researchers have recently concluded that the tooth and beeswax are both 6,500 years old. The Neolithic people of the time were sheep breeders who may have used their teeth as “a third hand,” said a researcher. There is other evidence of prehistoric dentistry, such as tooth drilling which occurred in Pakistan over 7,500 years ago.
