If you get richer your teeth could get worse (if you eat more sugar foods) or better (because of better health assistance or, even, more education and health-conciousness). These variables can be analysed with these data, downloaded from Gapminder Data:
- Bad teeth per child (12 yr, WHO)
- GDP/capita (US$, inflation-adjusted, World Bank)
- Government health spending per person (US$, WHO)
- Sugar comsumption per person (g per day, FAO)
- Literacy rate, adult total (% of people ages 15 and above, UNESCO)
