Contrary to long-held stereotypes and cultural jokes, a comprehensive study has debunked the myth of superior American dental health compared to the English. The study, published in the BMJ, presents a detailed comparative analysis of oral health between the United States and England, revealing that Americans have a higher mean number of missing teeth and wider socioeconomic disparities in dental well-being.
The research was conducted by a team based in the UK and the US, utilizing data from two nationally representative surveys: the English Adult Dental Health Survey (ADHS) and the US National Health and Nutrition Examination Survey (NHANES). The study’s findings are particularly significant given the ingrained belief, perpetuated through American media from “The Simpsons” to “Austin Powers,” that the British have notoriously poor dental health—a belief that has persisted for over a century.
Analyses were conducted on adults aged 25 years and older, with samples consisting of 8,719 individuals from England and 9,786 from the US for educational assessments, and 7,184 from England and 9,094 from the US for income analyses. Key outcomes measured included the number of missing teeth, self-rated oral health, and the impacts of oral health on daily life.
Findings from the study showed a mean number of missing teeth of 7.31 in the US, marginally higher than England’s 6.97, counter to common assumptions. England, however, reported more frequent oral impacts on daily life. A salient discovery from the research is the evidence of marked social gradients in oral health, with the US exhibiting wider educational and income inequalities compared to England across all oral health measures.
The study suggests that greater social inequalities in the US, differential access to treatment services in the health systems, and the influence of risk factors such as sugar consumption and smoking may contribute to these disparities. Furthermore, the role of welfare policies, with England’s more comprehensive “safety net” measures, may be a factor in mitigating oral health inequalities.
