Overall, the prevalence of both partial and total tooth loss in adults has decreased from the early 1970s until the latest (1999-2004) National Health and Nutrition Examination Survey. In spite of this improvement, significant disparities remain in some population groups.
Tables 1 and 2 present information about tooth loss for adults age 20 to 64 years and for selected population groups.
Number of Teeth Remaining (Table 1)
- Adults age 20 to 64 have an average of 24.92 remaining teeth.
- Older adults, Black adults, current smokers, and those with lower incomes and less education have fewer remaining teeth.
Number of Adults with Total Tooth Loss (Table 2)
- 3.75% of adults 20 to 64 have no remaining teeth
- Older adults, Black and Hispanic adults, current smokers, and those with lower incomes and less education are more likely to have no remaining teeth.
