Oral health disparities can partly be attributed to differences in socioeconomic status. Over a three year study researchers were given surveys about their access to healthcare, nutrition, and laboratory tests. This research stated that patients with low income had the highest prevalence of not having a dentist and wealthier patients had a much higher prevalence (Kailembo et al., 2018). These results were especially true of adult males, current smokers, as well as Hispanics, and people with a low educational level. These groups tend to have less disposable income so they are not readily going to the dentist frequently.
