Dental insurance is designed to share the cost of preventive and necessary oral care, but it’s structured differently from medical insurance. Most plans use a 100-80-50 model: preventive care (cleanings, exams, X-rays) is typically covered at 100%, basic procedures (fillings, simple extractions) around 70–80%, and major work (crowns, bridges) about 50%.
Patients usually pay a monthly premium, plus a deductible before coverage begins for non-preventive services. Plans also have an annual maximum (often $1,000–$2,000), which is the most the insurer will pay each year—after that, you pay out of pocket.
Many plans use a network of dentists who agree to set fees. Staying in-network lowers costs, but some plans allow you to go out-of-network with partial reimbursement.
There may also be waiting periods for major procedures and limitations on frequency (e.g., two cleanings per year). Overall, dental insurance helps with routine care but offers limited protection for high-cost treatments.
