It seems our ancestors- at least those who trace back to Rome or Briton- had better teeth then us. A recent study found that Romans and Britons around about 200-400 AD had a lot fewer signs of gun diseases and tooth issue then we have today! But don’t worry, it’s not like they were super healthy. The average life expectancy back then was a scant 40 years old. See more details here: Roman-Britons had less gum disease than modern Britons.
