Interviewer instructions

The question serves to identify people who are suffering from edentulism (who are missing all of their teeth), a particularly debilitating oral disease. If left untreated, edentulism can lead to the shrinking and loss of jawbone. Record a response of “yes” only if the respondent has lost all of their natural teeth, and not just some or most of them.
