True or false: Oral health care systems which emphasize prevention will yield populations with good oral health; those that do not, will not.

• A. True
• B. False
• C. Not enough information
• D. Partially true

Answer: (A)

Prevention has a powerful impact on how a population fares in oral health. When care systems prioritize prevention, they implement measures like fluoride programs, dental sealants for children, education on brushing and flossing, and routine early screening. These steps reduce the number of new caries lesions and help catch problems before they become serious, which lowers overall disease burden, improves quality of life, and often reduces costs since treating disease after it develops is more resource-intensive than preventing it. Conversely, systems that focus mainly on treating problems once they occur tend to see higher disease prevalence and greater unmet needs, because incidence remains higher and access or adherence to care can be inconsistent. While real-world factors matter, the general expectation is that prevention-centered systems yield better oral health for populations.
