Which of the following dental procedures is commonly excluded from coverage under a dental policy?

The correct answer is endodontics, which commonly includes procedures such as root canals. While many dental insurance policies provide coverage for basic procedures such as tooth extractions, fluoride treatments, and X-rays, endodontic treatments can often be excluded due to their complexity and cost. Insurance providers may classify these procedures under a higher tier of dental care that is not covered or may impose stricter conditions or higher deductibles for such treatments.

In contrast, tooth extractions are generally considered a standard procedure and are usually covered by most dental insurance plans. Fluoride treatments are often covered as preventive care, particularly for children, and X-rays are essential diagnostics that most plans include under preventive services. Thus, endodontics stands out as a procedure that insurance providers frequently do not cover.
