Relationship Between Tooth Loss and Memory Loss? (European Journal of Oral Sciences)


A recent critical appraisal from NHS Choices “Behind the Headlines” evaluates claims of a possible causal relationship between tooth loss and memory loss in healthy older people. A small study of older people has found that the loss of natural teeth is significantly associated with poorer performance on cognitive tests. More research would help investigate the reasons for this association, but this critical appraisal reminds readers that it would be unwise to confuse a statistical correlation with causation.

“Overall, this was a small but well-conducted study. While it suggests that there may be a link between tooth and memory loss, any association is likely to be small, of unclear clinical significance, and needs to be confirmed in larger prospective trials”.
