It's not possible to state exactly how many 70-year-olds have all their teeth, but we can infer some information from the provided reference about tooth loss. The reference focuses on the average number of teeth remaining and the percentage of people with no teeth at various ages, rather than on those who have all of their teeth.
Here's a breakdown of what the reference tells us:
Tooth Retention Statistics
| Age Group | Average Teeth Remaining | Percentage with No Teeth |
|---|---|---|
| Around 64 | Approximately 22 | N/A |
| 50 to 64 | N/A | 10% |
| 74 | N/A | 13% |
| Over 74 | N/A | 26% |
Inferences and Analysis
- The data does not specify the number of people with all their teeth.
- The reference indicates that by 64, the average person has around 22 teeth. Since a full set of adult teeth consists of 32 (or 28 if wisdom teeth are removed), many people have already lost some teeth by this age.
- The percentage of people with no teeth increases with age. By age 74, 13% of people have no teeth, and this percentage increases dramatically after 74.
- There is a significant difference in the statistics given between 64 and 74. While we cannot use these to calculate the numbers of 70 year olds with all their teeth, we can estimate that the numbers will be between these two brackets.
Therefore, while the reference offers insights into tooth loss, it does not provide a specific number or percentage of 70-year-olds who retain all their teeth. Based on the trend of increasing tooth loss with age, we can infer that a small minority of 70-year-olds will likely have all their teeth.
