10. France
DMFT Score: 1.2
The number 10 spot is awarded to France because of a pretty good DMFT score of 1.2., meaning that out of all the children put through the DMFT survey, they had about 1.2 defective teeth on average. This is definitely a remarkable number, but France merely is number 10 on our list and things will only get better from here on. The closer the score is to zero, the better.
