Gums healthier in Roman times

People had far less gum disease in the Roman era than today, and oral health has seriously worsened despite the advent of toothbrushes and dentists, say researchers.

A study of 303 skulls at the UK’s Natural History Museum, dating from the years 200 to 400 AD, has found that only 5% showed signs of periodontitis, compared with around 15 to 30% of modern Western adults.
