Which of these is typically considered a preventive dental service?

• A. Fluoride treatment
• B. X-rays
• C. Restorative fillings
• D. Dentures

Answer: (A)

Preventive care aims to stop decay and protect teeth before problems arise. Fluoride treatment fits this goal because fluoride strengthens enamel, promotes remineralization, and makes teeth more resistant to acid attacks, reducing the risk of cavities. It’s commonly applied in the office as a varnish, gel, or foam and is a standard preventive step in routine dental visits. In contrast, X-rays are diagnostic tools used to detect issues that may already be developing, while restorative fillings repair decay that has occurred and dentures replace missing teeth.
