Prevalence of and factors associated with unmet dental need among the US adult population in 2016.

Future policies should continue to address cost and coverage barriers to adult dental care, as these remain significant barriers to access, particularly for low-income adults. Future research should evaluate the reasons adults report unmet dental need and explore how adults' judgment of dental need compares to providers' clinical judgment. Additionally, research that explores how race and ethnicity affect perceptions of unmet dental need is warranted.
