Neanderthals had primitive dental care
Grooves have been found on 130,000-year-old Neanderthal teeth that appear to indicate the use of toothpicks, and impacted or rotated teeth got extra attention. Research in the Bulletin of the International Association for Paleodontology by David Frayer and Davorka Radovcic of four Neanderthal teeth showed signs of grooves consistent with the use of toothpicks, along with occlusal wear.
