Finer Pearly Whites!

Yes, even dental health has improved markedly in recent decades. Check out this chart from WHO:

Cavity Data

 

Note that none of the developed countries on the chart averaged fewer than two “Decayed, Missing or Filled Teeth” (DMFT) for twelve year olds in 1980. It’s amazing that kids in Japan, New Zealand, Italy and Iceland averaged five or more DMFTs 30 years ago! Also note the amazing convergence of all these countries between one and two DMFTs in the 2000s.

What’s true for teeth is true for most other things: bad stuff is in major decline!
