Which statement best describes the relationship between dental caries and socioeconomic status?

• A. Dental caries is strongly related to low socioeconomic status
• B. Dental caries is unrelated to socioeconomic status
• C. Dental caries is higher in high socioeconomic groups
• D. Dental caries is determined solely by genetics

Answer: (A)

Understanding how dental caries relates to socioeconomic status starts with recognizing caries as a multifactorial disease shaped by both biology and environment. Socioeconomic status influences key factors that drive caries risk: access to preventive dental care, availability of fluoride (through water fluoridation or products), health education, and dietary patterns. People in lower socioeconomic groups often face barriers to regular checkups, fewer opportunities for preventive services like sealants or varnishes, and greater exposure to cariogenic foods due to cost and availability. These conditions increase the likelihood of developing caries and experiencing untreated decay compared with higher socioeconomic groups that typically have better access to care and prevention. Genetics do play a role in susceptibility, but caries is not dictated by genes alone; the environmental and behavioral context is a major driver. Thus, dental caries is strongly related to low socioeconomic status.
