What fraction of people have untreated tooth decay?

Explanation:
Understanding how common untreated tooth decay is helps gauge access to care and how well preventive efforts are working. About one in five people have untreated tooth decay, which means roughly 20% of the population is living with decay that hasn’t been treated with fillings or other services. This figure reflects barriers to care, affordability, and timely dental treatment as much as it does the presence of decay itself. If the rate were one in ten, the burden would be smaller; one in three or half would indicate a much greater, more widespread problem. So, the best interpretation is that about 20% of people have untreated tooth decay.
