Children from low-income households are three times more likely to have untreated cavities in their primary teeth than children from higher-income households. About one in four children living in poverty have untreated cavities.

About one in three preschoolers living in poverty have some form of early childhood caries.

Low-income children are less likely to receive regular dental care, and cavities are more likely to go unfilled. This can lead to more severe forms of the disease.
