Is dental caries inherited?

• A. Yes
• B. Only when maternal factors present
• C. Depends on fluoride exposure
• D. No

Answer: (D)

Dental caries risk is not inherited in a simple genetic sense; it’s a multifactorial condition driven by the interaction of biology, environment, and behavior. While genetic factors can influence aspects like enamel quality, salivary flow, and immune response, the development of cavities depends mainly on factors you can modify—how often you eat fermentable sugars, how well you remove plaque, the quality of saliva, tooth surface, and fluoride exposure. Early bacterial exposure from caregivers can affect which microbes colonize the mouth, but this is about microbial transmission rather than inheritance of the disease. Fluoride use and good oral hygiene significantly alter risk, underscoring the environmental nature of caries. So, while genetic predisposition may play a role, dental caries itself is not inherited as a straightforward trait.
