5. Sweden
DMFT Score: 0.8
We are half way through our list of top 10 countries with the best and straightest teeth and oral health in the world, and at number 5, we have Sweden with a DMFT score of 0.8, which is, as you can see 0.1 less than our previous entry Switzerland. To have a DMFT rating below one is rather ideal, and to push it even further takes a lot of dedication and self-restraint. Sweden seem to be doing it the right way.
