1. Routine cleanings and exams in a dental plan fall under which category of treatment?

Preventive and diagnostic care

Preventive and diagnostic services (cleanings, exams, x-rays) are usually covered at the highest level.

2. A dental plan that pays a set amount per procedure regardless of the actual charge is a:

Scheduled (indemnity) plan

A scheduled plan lists a fixed benefit per procedure; the insured pays any difference from the dentist's charge.

3. A comprehensive (nonscheduled) dental plan:

pays a percentage of the usual, customary, and reasonable charge for each procedure

A comprehensive plan reimburses a percentage of UCR charges rather than a fixed schedule of amounts.

4. Orthodontic coverage in a dental plan:

covers correcting misaligned teeth, commonly subject to a separate lifetime maximum and often limited to dependent children

Orthodontia is a distinct category that corrects misaligned teeth, usually with its own lifetime maximum.
