Which of the following is a preventive service provided by the oral health program?

The choice of oral hygiene as a preventive service highlights its essential role in maintaining oral health and preventing dental diseases. Preventive services in oral health focus on avoiding the onset of dental issues before they become more serious and require more invasive treatments.

Oral hygiene education and practices, such as proper brushing and flossing techniques, are foundational elements that help individuals manage their own dental health. By promoting good oral hygiene, the program aims to reduce the likelihood of cavities, periodontal disease, and other oral health issues that can arise from poor dental care.

In contrast, temporary and permanent fillings, extraction of teeth, and restorative treatments are all reactive measures taken after dental problems have already developed. These interventions address issues rather than prevent them, making oral hygiene education a pivotal preventive service within the oral health program.
