How dental coverage is structured
Published May 30, 2026
Dental insurance is structured differently from medical insurance, usually around routine cleanings and a tiered split for other care. Understanding the common 100-80-50 structure and the annual maximum helps you know what to expect at the dentist.
The 100-80-50 structure
Many dental plans pay 100% for preventive care like cleanings and exams, around 80% for basic care like fillings, and about 50% for major work like crowns. Your share rises as procedures get more complex.
Annual maximums and waiting periods
Dental plans often cap what they pay per year with an annual maximum, after which you pay the rest. Some plans add waiting periods before major work is covered.
Networks
Like medical plans, dental plans usually cost less in network. Confirm your dentist participates before assuming the higher coverage levels apply.
