Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
The case definition is "lost all teeth due to caries or periodontal diseases"; however, because cause of tooth loss is not feasible to identify, the absence of 32 natural teeth (including third molars) is used as a proxy. This indicator is tracked using the Oral Health Examination component of the Continuous National Health and Nutrition Examination Survey, collected since 1999. The measurement protocol has been described.
