4. Gabon
DMFT score: 4.9
Gabon is a Central African country and is the only African country to make the list today. The thing is, sugar has been found to be the primary reason behind tooth decay and other problems, and in African countries, candies and sweets are not a priority for children. This is why most African countries have relatively low DMFT scores. Of course, these scores are nowhere near optimal, but in comparison things are good. Except for Gabon of course, as you can see that Gabon has a DMFT score of 4.9.
