Which of these is typically regarded as a major treatment in an individual dental plan?

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

Answer: (D)

In a dental plan, treatments are categorized by how invasive and costly they are, typically as preventive, basic, or major. Major treatments are those that replace missing teeth or require substantial procedures, multiple visits, and lab work. Dentures fit this, because they replace an entire arch of missing teeth and involve impressions, lab fabrication, fittings, and ongoing adjustments, along with a higher cost and longer treatment timeline. They address functional needs like chewing and speaking, as well as aesthetics, making them a classic example of a major service.

Fluoride treatment is preventive, helping prevent decay. X-rays are diagnostic imaging used to detect problems. Restorative fillings repair decay in a tooth and are generally considered basic or minor restorative work, not as extensive as dentures.
