Explanation

Dental plans typically classify services as preventive (cleanings and exams, often covered at or near 100 percent), basic (fillings and simple extractions), and major (crowns, bridges, and dentures), frequently applying deductibles and an annual dollar maximum. Inpatient and outpatient, accident and sickness, and skilled and custodial are classifications used in other kinds of coverage, not dental. Knowing the preventive-basic-major structure helps explain why dental plans emphasize low-cost preventive care.
