The nation's teeth are soon to be examined in a new survey.
The New Zealand Oral Health Survey will question 2000 adults and 1000 children about the oral health services they use.
The survey will be conducted from March to November and will involve face-to-face interviews and dental examinations.
The results will be used to recommend oral health programmes and services, Ministry of Health chief dental officer Robin Whyman said.
Similar surveys were conducted in 1976 and 1988.
