Diet and dental disease

Molars in the jaw of an older middle-aged individual from the Neolithic site of Çatalhöyük showing large dental caries lesions

Using tooth wear and decay patterns in the investigation of dietary change

Tooth decay is directly related to carbohydrate consumption and the two largest changes in dental health worldwide have been the adoption of agriculture and the rise of sugar consumption in the greatly expanding cities of the 19th century. This is strongly reflected in human remains from archaeological sites.

Lower dentition of middle-aged Chiribaya man from the Osmore Valley in southern Peru (AD 1000-1400) showing large lesions of dental caries

Up until the rise of cultivated, starch-rich crops, dental caries (decay) was extremely rare. Amongst early agriculturalists, it was more frequent but was in particular a disease of the very worn teeth of older people. In cities after the industrial revolution a softer diet mean much less wear and the rise of sugar caused caries rates to soar. Many more children and younger adults started to show the condition which took on a character much more like that of the 20th century.

These changes can be found in many parts of the world and make the rate and pattern of dental caries, together with tooth wear, a very useful tool for investigating dietary change. This project involves collaborations in Peru, Turkey and Portugal.
