Irish Famine victims were heavy smokers, which caused badly rotten teeth, according to researchers at the University of Otago and Queen’s University Belfast. The study examined the teeth of 363 adult victims of the Great Irish Famine who died in the Kilkenny Union Workhouse between 1847 and 1851. Their remains were discovered in an unmarked mass burial ground by archaeologists in 2005. 

The findings show poor oral health among most of the famine victims, with 80% of the adult remains showing evidence of tooth decay and more than half missing teeth. There also were revealing signs of pipe smoking marks on their teeth. According to the researchers, this is the first study to explore the relationship between smoking and oral health in an archaeological sample of a historical population.

Professor Eileen Murphy of the School of Natural and Built Environment at Queen’s University Belfast said that this research is important as the current clinical understanding of how smoking affects oral health is not fully understood, and this study adds to that discourse.

“As well as this, the study also gives us a unique insight into the living conditions of the working classes in Victorian Irish society at the time of the Great Famine,” said Murphy.

“Smoking was evidently an important part of life for these people, a habit that they could enjoy amongst deprived social conditions and a very harsh and difficult life, but it may have contributed to their ill health,” Murphy said. “Despite a vast amount of historical records surviving from the nineteenth century, very little is known about the experienced living conditions of the poor and laboring classes.”

“We believe the bad condition of the teeth studied was because of widespread pipe smoking in both men and women, rather than their diet of potatoes and milk, as a comparative study of the twentieth century population on the same diet didn’t have the same evidence of poor oral health,” said Jonny Geber, PhD, of the Department of Anatomy at the University of Otago. 

“Our study shows that it is not only diet that affects your oral health, but many other factors, and we believe that smoking was a major contributing factor in the Kilkenny population sample,” Geber said. “The current study adds to the growing body of evidence that demonstrates that smoking is not only bad for your health, it is also bad for your teeth.”

The study, “Dental Markers of Poverty: Biocultural Deliberations on Oral Health of the Poor in Mid-Nineteenth-Century Ireland,” was published by the American Journal of Physical Anthropology.
