Which of the following barriers can hinder children's access to dental care?

Lack of insurance and transportation are significant barriers that can hinder children's access to dental care. Without insurance, families may struggle to afford necessary dental services or preventive care, leading to untreated dental issues that can progress over time. Transportation is also a critical factor; if families lack reliable transportation, they may find it difficult to attend dental appointments, especially if the dental clinic is not within walking distance. This combination can severely limit the ability of children to receive timely and necessary dental care.

In contrast, high education levels of parents typically correlate with better health outcomes and may increase the likelihood of prioritizing dental care for their children. The availability of multiple pediatric dentists generally enhances access to care by providing families with more options. Lastly, affordable dental products in stores can encourage preventive oral health practices at home, but do not address the need for professional dental services that children might require.
