Oral Health Surveillance Report, 2019 :This surveillance report provides national estimates for selected measures for oral health status during 2011–2016

Dental Caries in Primary Teeth

Children Aged 2–5 Years - Overall, the prevalence of dental caries in the primary teeth of children aged 2–5 years was 23%, reflecting a decrease of 5 percentage points since 1999–2004.

Children Aged 6–8 Years - Although no change was detected in the prevalence of caries in primary teeth (52% during 2011–2016), untreated decay prevalence declined overall (28% vs. 16%)

Dental Caries in Permanent Teeth of Children and Adolescents

Children Aged 6–11 Years - Overall, both prevalence of caries (21% vs. 17%) and untreated decay (8% vs. 5%) decreased

Adolescents Aged 12–19 Years - Overall, untreated tooth decay prevalence decreased (20% vs. 17%), whereas dental caries prevalence had no detectable decrease (59% vs. 57%).


Dental Caries Among Adults and Older Adults

Adults Aged 20–64 Years - Between the two survey periods, the overall prevalence of caries decreased slightly, but no difference was detected in untreated decay, with 9 in 10 adults affected by caries and 1 in 4 affected by untreated tooth decay.

Older Adults Aged 65 Years or Older - Among older adults, a small increase was found in the prevalence of caries, but no change was detected in the prevalence of untreated decay. More than 9 in 10 adults had experienced dental caries, and 1 in 6 had untreated tooth decay.


Edentulism and Tooth Retention

Adults Aged 20–64 Years - The percentage of adults who have lost all of their teeth decreased from 4% during 1999–2004 to 2% during 2011–2016. Among younger adults aged 20–34 years, too few people were edentate to generate stable estimates, suggesting that edentulism is rare among this group.

Older Adults Aged 65 Years or Older - Overall, about 1 in 6 (17%) older adults had lost all of their teeth during 2011–2016, a decrease of more than 30% compared to 1999–2004 (27%).
