According to scientists, as we moved from being hunter- gatherers to farmers, our diets altered and thereby negative or adverse changes were seen in oral bacteria. Further as we, the people again moved to start manufacturing food during the Industrial Revolution.
A Study conducted one the evolution of out teeth over the last 7,500 years prove that today we have less diverse oral bacteria than ancient population, which the scientists believe have contributed to oral chronic diseases in post-industrial lifestyles.
Scientists studied the extracted DNA from tartar (calcified dental plaque) from 34 prehistoric skeletons from northern part of Europe. They analysed the changes in the nature of oral bacteria that used to be present in prehistoric hunter-gatherers, through to the Bronze Age when farming became established, then to Medieval times and finally to the Industrial Revolution and later.
Prof. Dobney from the University of Aberdeen, explained how this study shows the facts on how people lived and died in the past. He also explained that humans suffer from today if we know the genetic history of diseases. "Being able to track them through time has huge implications for understanding the origins and history of human health - making the archaeological record extremely relevant and important to modern-day medics and geneticists," Dobney added.
The authors in an abstract in “Nature Genetics” wrote that "modern oral microbiotic ecosystems are markedly less diverse than historic populations, which might be contributing to chronic oral (and other) disease in postindustrial lifestyles."
Control of background levels of bacterial contamination became possible when ACAD’s super clean labs and stringent decontamination and authentications protocols were made available.
Evidences have been seen which show that beeswax was used 6,500 years ago in dentistry.

Study leader Professor Alan Cooper, ACAD Director, said, "This is the first record of how our evolution over the last 7500 years has impacted the bacteria we carry with us, and the important health consequences."
