It’s been said that math is the universal language. But math can never communicate as much as a smile does — and a smile means the same thing in every nation. Unfortunately, however, the smiles in some countries aren’t as healthy as those in others. The most acceptable measure of a large population’s oral health is the DMFT index. DMFT stands for decayed, missing, filled teeth. The DMFT index is widely used when assigning a numerical value to a population’s oral health and hygiene condition, and is determined by dentists examining a sample group from the population. Here is a list of countries that have fared very well on DMFT index and are rated the best in the world for oral health.
