Association between the number of missing/replaced teeth and Chronic Kidney Disease (CKD): cross-sectional analysis of NHANES data

Paper C Peer reviewed Observational

Key takeaways

Using data from over 10,000 U.S. adults, this study found that people with fewer natural teeth or more missing/replaced teeth were more likely to have chronic kidney disease. Because it is a snapshot in time, it shows a link but cannot prove that poor dental health causes kidney disease.
